Abstract

PROBLEM TO BE SOLVED: To provide a recording apparatus which realizes extended control for satisfying user's peculiar tastes and convenience while reducing a maker's burden. SOLUTION: When an extended attribute section is to be specified in batch mode for a reproduction path set for a TS-VOB (transport stream video object), a section marker is generated in the VOB information to specify the position of the extended attribute section for the TS-VOB. When a section to be subjected to extended control is to be specified individually for one reproduction path, a section marker specifying the position of the extended attribute section is generated in the PGC information for the reproduction path. The VOB information and the PGC information generated are written onto a DVD.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a recording device, a reproducing device and a recording medium for recording a digital stream on a recording medium such as a DVD, a CD, a HD and a semiconductor memory card.

[0002]

2. Description of the Related Art In commercializing the above-mentioned recording apparatus,
Maintaining compatibility of digital streams recorded on a recording medium can be said to be a serious responsibility for manufacturers of recording devices. In order to ensure this compatibility, manufacturers have been actively engaged in activities related to standardization and standardization of recording formats for recording media.
Various uniform standards have been established, such as the DEO RECORDING standard.

While keeping pace with the establishment of a unified standard, each manufacturer tends to commercialize a recording device with "extended control" as a selling point in order to differentiate it from other companies' products. The "extended control" is a reproduction control in which the manufacturer of the recording apparatus can determine the content by its own judgment. Since the format standardized by the DVD-VIDEO RECORDING standard has universal value, it is not allowed for any manufacturer to perform playback control contrary to this content. On the other hand, since extended control does not necessarily require universal value, contents with a strong color of product strategy and contents with a strong trend can be defined as control contents for one manufacturer.

[0004]

However, when multi-user type optical discs have become widespread, even if the above-mentioned extended control can be differentiated from the products of other companies, the user's satisfaction in the true sense can be achieved. You may not be able to get it. The multi-user type optical disc is an optical disc used in a form shared by a plurality of users, and it is expected that this form will be adopted in an optical disc having a large capacity of 40 Gbytes or more. In the reproduction control of the multi-user compatible optical disc, it is not necessary to perform uniform reproduction control for all users. In today's "era of individuality", the attention and convenience of each user should be respected, and even when playing multi-user compatible optical discs, extended control that responds to each user is required. To be On the other hand, for each of a plurality of users who share one recording medium, performing individual extended control for each user means that the data format of the recording medium and the processing on the device side increase as the number of users increases. It has to be complicated and causes a burden on the manufacturer.

An object of the present invention is to provide a recording apparatus that realizes extended control that can satisfy the user's attention and convenience while reducing the burden on the manufacturer.

[0006]

Now, how to achieve the above-mentioned object will be described. In multi-user correspondence, a typical extended control that should be performed individually for each user is to find the unviewed portion. This is because the unviewed portion is different for each user, and it is meaningful to reproduce from a different position for each user. A typical extended control that should be performed uniformly for multiple users is playback skip for CM sections. This is because, in many cases, all users who share the recording medium desire to skip the CM section uniformly. Whether it is performed for a plurality of users all at once or individually for each user varies depending on the contents of the extended control. The starting point and ending point of the extended control during reproduction of the digital stream also depend on the contents of the extended control.

In the conventional extended control, a portion where the extended control is to be executed is described by "position", that is, "point" on the digital stream by using information called entry point information. However, in the conventional notation with "dots",
There is a limit to the details of extended control. Even if the section for which extended control is to be performed can be specified by combining location information, it is shown until it is specified whether this should be performed uniformly among multiple users or individually by each user. However, there is a possibility that it will not be possible to follow the diversification of extended control that accompanies multi-user support.

In order to cope with the diversification of the extended control accompanying the multi-user correspondence and to achieve the above-mentioned object, the recording apparatus according to the present invention indicates the content of the extended control performed at the time of reproduction by one reproduction path information. If it is valid only within the playback path that is specified, the section for which extended control is to be performed is individually specified for that playback path (1), and if it is valid in multiple playback paths, it is indicated by multiple playback path information. Specify the sections for which extended control should be performed collectively for multiple playback paths
(2) Designating means, marker information of the first type indicating where the section individually designated by the designating means exists in the reproduction path, and where the section collectively designated in the digital stream exists And a writing unit that writes at least one of the second-type marker information indicating whether or not to write in the recording medium.

[0009]

BEST MODE FOR CARRYING OUT THE INVENTION (First Embodiment) An embodiment of a recording medium according to the present invention will be described below. The recording medium according to the present embodiment is a rewritable DVD (hereinafter abbreviated as “DVD”) capable of recording moving image data according to the DVD-VIDEO RECORDING standard. FIG. 1 is a diagram showing a DVD 1 and a recording device 100 according to the present embodiment. The recording device 100 encodes the broadcast content of the broadcast signal received via the terrestrial antenna 101 and the parabona antenna 102, and writes it on the DVD 1. This DVD 1
Is a multi-user compatible DVD shared by two users (user A and user B) in the figure.

The DVD 1 has a physical layer, a file system layer,
The recording device 10 has a layer hierarchy such as an application layer.
Data of digital stream format is recorded by 0. FIG. 2 is a diagram showing the structure (file structure) of the DVD 1 on the file system layer by drawing it out with a dashed arrow. In the file structure shown in FIG. 2, a DVD_RTAV (RealTime Recording Audio Video) directory is arranged directly under the ROOT directory, and under that, several TS-VOBs are recorded as AV files and various management information is recorded. Files and are placed. TS (Transport Stream) -TS-VOB
(Video Object) is stream format data recorded in the transport stream format, and is distinguished from the program stream format VOB. "Claims" and "Claims" of the application

[0011]

[Means for Solving the Problem] The digital stream referred to in "" is this TS-VOB. FIG. In this figure, the AV file shown in Fig. 2 is shown in the lowermost seventh row.The sixth row in Fig. 3 shows the TS-VOB recorded in the AV file. As shown in TS-VOB
Is obtained by multiplexing the video stream and audio stream shown in the first row. The video stream located in the first row consists of multiple picture data.
It is an array of pi1,2,3 .... All of these picture data are displayed during one display period (also called a video frame) of the display. In the NTSC system display, the video frame is about 33msec (1/2 to be exact)
The video frame is 40 msec in the PAL system display. These picture data have been compression-coded based on the correlation between the frames. Therefore, the picture data forming the video stream is compressed using the correlation with the images to be reproduced in the past direction and the future direction.
y Predictive (B) picture, Predictive (P) compressed using the correlation with the image to be played in the past direction
There are types such as pictures and Intra (I) pictures that are compressed using the spatial frequency characteristic in the image for one frame without using the correlation.

The minimum unit that can be decoded in a video stream is called GOP (Group Of Picture). GOP is at least
A set of picture data including one I picture and having a reproduction time of about 1.0 second. The video stream shown in the first row in FIG. 3 is divided into a plurality of GOPs in the second row. Since the compression coding method for picture data is a variable code length method, GOP data lengths are different from each other. When recording on a DVD, the GOP sequence is divided into a plurality regardless of the size of each GOP. The divided part obtained by the division is the PE shown in the third row.
It is stored in the S packet sequence. On the other hand, the audio stream located on the right side of the first row is also divided into a plurality of pieces, and the divided portions obtained by the division are stored in the PES packet sequence shown in the third row. A PES packet is a packet that stores a divided portion of a video stream and an audio stream, as shown in the third row of FIG. , "PTS" indicating when to display the decoding result of this part is added to the header.

The PES packet sequence storing the GOP sequence is multiplexed with the PES packet sequence storing the audio stream (tj1 in the figure) to form the TS packet sequence shown in the fourth row. One or more GOPs and audio data multiplexed with this picture data form a VOBU (Video Object Unit) as shown in the fifth row. VOBU
Is the minimum access unit of TS-VOB, and is configured by arranging video packs-audio packs in the MPEG standard. The TS-VOB shown in the sixth row has a configuration in which multiple VOBUs are arranged in time series. The above is the internal structure of TS-VOB.

The division and multiplexing shown in the third to fifth stages are unique to TS-VOB, which is different from the conventional DVDs. The VOB recorded on the conventional DVD, that is, the VOB in the program stream format, is composed of a plurality of packs, and one PES packet is stored in each pack as it is. On the other hand, in the transport stream format TS-VOB, a PES packet is divided into a plurality of pieces and then stored in each TS packet. FIG. 4 is a diagram showing how PES packets are stored in TS packets.

The structure of the TS packet is as shown in the third row of FIG. 4, and is composed of a "TS packet header", an "applied field", and a "payload section". 188Byt
have a size of e. This data size of 188 bytes is the same size as the ATM packet transmitted on the ATM transmission line, and care is taken so that it can be recorded as it is with the packet transmitted on this transmission line.

The "payload" stores a divided portion obtained by dividing the PES packet into a plurality of pieces.
If the PES packet is part of the video stream, this payload corresponds to the video layer. First in FIG.
The PES packet shown in the second row is divided into a plurality of pieces as shown in the second row, and each divided portion is stored in the payload of the TS packet in the third row as indicated by arrows ct1, 2, and 3. It

The structure of the "TS packet header" is shown by a broken line arrow hg1. As shown by arrow hg1, “TS
"Packet header" is a "PID (Packet Identifier)" that identifies which video stream or audio stream a TS packet belongs to.
And a "unit start indicator" that indicates where the PES packet in the payload is from, followed by
“Applied field control information” indicating whether or not the applicable field is continuously present in the TS packet is stored.

The "applicable field" describes information about the system layer of the video stream when the divided portion of the video stream is stored in the payload. Information on such system layers is indicated by the dashed arrow hg2.
"PCR (Program Clock Referenc
e) ”and“ Random access display flag ”. PCR is the reference clock (STC (sy
stem time clock)) reference value. The reference value for what kind of processing is the reference when performing the processing of demultiplexing the transport stream (1) and the processing of reconstructing the transport stream into various PES streams such as video streams (2). It is a value. The "random access display flag" indicates whether or not the first frame of the access point of the video stream is stored in the PES packet of the corresponding payload part. The access point is a unit that can be independently decoded inside the stream, and the random access display flag indicates whether or not the head frame (I picture) of the GOP exists.

The above is the difference between the TS-VOB and the program stream format VOB. Next, how the TS-VOB is recorded on the DVD will be described. The DVD has a plurality of ECC blocks that are error-correctable recording areas. A plurality of TS packets forming the transport stream are converted into a unit called a capsule and recorded in an ECC block. The capsule is formed by arranging a plurality of TS packets with ATS added. ATS (Arr
(ival Time Stamp Information) is information indicating the timing when the TS packet reaches the inside of the device.

Next, the internal structure of the management file will be described. FIG. 5 is a diagram showing the internal structure of the management file. As indicated by the dashed arrow fs0 in this figure, the management file contains multiple VOB information (VOB # 1 information, VOB # 3 information,
B # 3 information ...) and multiple PGC information (PGC information # 1, # 2, # 3 ...
・) And and. “VOB information # 1, # 2, # 3 ...” is information indicating details of each TS-VOB in the DVD. The broken line hs1 in the figure shows the details of the VOB # 1 information corresponding to VOB # 1 among these VOB information.

As indicated by the lead line hs1, the VOB # 1 information is "TS-VOB identifier" that uniquely identifies the corresponding TS-VOB, and "TS-VOB recording date and time" that indicates when the TS-VOB was recorded. ], "Video coding mode" indicating how the video stream multiplexed in TS-VOB is compressed and encoded, "Video coding mode" in which the audio stream multiplexed in TS-VOB is compressed and encoded "Audio coding mode" that indicates whether or not it is compatible, corresponding TS-V
It has "access map" and "section marker" for OB.

The "access map" is a reference table for indirectly referring to the addresses of a plurality of cue positions in the TS-VOB using time information. Leader line hs2,
By tracing hs3, the access map will be refined in order. The access map consists of entry information corresponding to each VOBU as shown by the leader line hs2,
Each entry information is, as indicated by the leader line hs3, "VOBU playback time" indicating the length of time required for playback of that VOBU.
And “VOBU size” indicating the data size of the VOBU itself are associated with each other. Since the variable-length code compression method is adopted, even if the size of each VOBU including GOP and the playback time vary, it is possible to respond to the playback time from any playback time by referring to this "entry information". VOBU
It is possible to find the beginning of the picture data inside.

Next, the internal structure of PGC information will be described. As indicated by the lead line hs4, the PGC information is composed of "reproduction path information" indicating the reproduction path of the TS-VOB to be reproduced through the access map and "section marker". Become. The characteristic of the reproduction path information is the notation. That is, since the access map exists in the management information, the reproduction path information is described in an indirect reference format using this as a reference table. TS-V describes the playback path information in the indirect reference format.
This is to eliminate the load of updating the reproduction path information when the OB is edited. Details of the reproduction path information will be described. As indicated by the leader line hs5, an array of cell information (cell information # 1, # 2, #
3 ...). Cell information, as indicated by the lead line hs6, "TS-VOB identifier" indicating the TS-VOB corresponding to the cell information, "start point information" which is time information indicating the reproduction start position in the TS-VOB, It is composed of "end point information" which is time information indicating the reproduction end position in the TS-VOB. A section in which the start point and the end point are specified by these time information is called a "cell", and the array of cell information in the reproduction path information indicates in what sequence these cells are reproduced. The playback path specified by such notation is TS-V
There are two types, one that is automatically generated at the time of recording by the recording device 100 that records the OB (1) and one that is recorded according to the user's editing operation (2). TS-VOB is played back on various routes. I'm keeping in mind.

FIG. 6 is a diagram schematically showing indirect reference by reproduction path information. In this figure, each of TS-VOB # 1 and TS-VOB # 2 is composed of multiple VOBUs.
Includes GOP. The access map in the VOB information specifies sector addresses of these multiple GOPs as shown by arrows ay1,2,3,4, and these sector addresses are indirectly referenced by way of the access map. . Arrows jy1,2,3,4 in the figure schematically indicate designation of GOP by time information. In other words, GOP designation by time information (arrow
jy1,2,3,4), TS via the access map
-An address of one of multiple GOPs included in VOB is specified. The playback path information in the figure is represented by these arrows jy1,2,3,
The playback path is represented by a set of time information according to 4.

Next, a description will be given of an application example in which the various types of information configured as described above are applied to a multi-user compatible DVD. FIG. 7 realizes multi-user support.
It is a figure which shows the data structure on DVD. In Figure 7, TS-VOB #
Two TS-VOBs such as 1 and TS-VOB # 2 are recorded on the DVD, and VOB information # 1 and # 2 are assigned to each of these TS-VOBs. Playback path information recorded with these
# 1 and # 2 are the two users (user A, user A) shown in FIG.
The playback path assigned to each of B) is specified. The playback path desired by user A is to play a part of TS-VOB # 1, a part of TS-VOB # 2, and a part of TS-VOB # 2 in that order, and the playback path desired by user B is TS-VOB # 1.
Part of VOB # 1 and part of TS-VOB # 2 are played in the order of. P assigned to user A
The GC information # 1 includes cell information # 1, # 2, # 3, and the PGC information # 2 assigned to the user B includes cell information # 4, # 5. In the cell information # 1 to # 5, the start point and the end point of a part to a part are designated by indirect reference. Since it is specified by the cell information, a part of ~ will be treated as a cell.

Arrows rf1 and rf2 in the figure symbolically indicate this indirect reference. As can be understood from these arrows rf1 and rf2, the start points of TS-VOB # 1 and TS-VOB # 2
st1, st2, st3, end points ed1, ed2, ed3 are TS-VOB # 1, TS-VOB #
It is specified by indirect reference via the access map corresponding to each of the two. The above is VOB information, PGC
Information. A feature of this embodiment is that in such a hierarchical structure, section markers are provided inside the VOB information and inside the PGC information. FIG. 8 is a diagram showing section markers provided inside the VOB information and inside the PGC information.

These section markers are a part of the reproduction path indicated by the reproduction path information, and are included in the recording device 1.
This is information for marking a section recognized as having an extended attribute by 00. "Extended attribute" is an attribute for which extended control is enabled, and when playing through the playback path, extended control is performed according to this extended attribute in the section specified by this section marker in the playback path. I'll do it.
The internal structure of the section marker included in the VOB information is as shown by the dashed arrow hs7 in FIG. 8, and the "attribute type" indicates what type of extended attribute the extended attribute section whose location is shown by itself has. , "Start point information" that is time information indicating where the start point of the extended attribute section is in the multiple playback paths referring to TS-VOB, TS
-“End point information”, which is time information indicating where the end point of the extended attribute section is in the multiple playback paths that refer to VOB, and what kind of extended control should be performed in this extended attribute section In other words, the “detailed information” indicates what can be the reference of the extended attribute section.

The section marker included in the PGC information is shown by being drawn out by a broken line hs8. The section marker is the "attribute type" indicating what type of extended attribute the section marker whose location is indicated has, and the start point of the extended attribute section among the multiple cells in the playback route corresponding to the playback route information. "Start cell ID" indicating which is included, "start point information" which is time information indicating the start point of the extended attribute section in the cell, and a plurality of pieces in the reproduction path corresponding to the reproduction path information "End cell ID" that indicates which of the cells includes the end point of the extended attribute section, "End point information" that is time information indicating the end point of the extended attribute section in that cell, It consists of "detailed information" indicating what kind of extension control should be performed in the extended attribute section, what can be the reference of the extended attribute section, and the like.

This section marker is used for VOB information and PGC.
The fact that there is information has the following significance. When the TS-VOB corresponding to the VOB information is referenced by a plurality of reproduction paths, the section marker in the VOB information is used to collectively specify the extended attribute section on the plurality of reproduction paths. On the other hand, the section marker in the PGC information is used when the TS-VOB corresponding to the VOB information is referenced by multiple playback paths, and when an extended attribute section is specified individually for a particular playback path. Used.

When there is an extended attribute section having an unviewed attribute in the reproduction paths for two users shown in FIG. 7, how to specify the extended attribute section will be described. FIG. 9 is a diagram showing an extended attribute section provided on the reproduction path for the user A. Intermediate position ty1 in part of the figure, end position yn1 in part
Is the start point-end point of the unviewed section that the user A has not yet viewed. The section marker existing in the PGC information # 1 is an indirect reference through the access map corresponding to each of the TS-VOB # 1 and TS-VOB # 2 and the cell information. Specify the end position yn1 of. As mentioned above, since the cell information itself indirectly refers to the position on the TS-VOB via the access map, the section marker is, so to speak, an extended attribute with an unviewed attribute due to "indirect reference to indirect reference". The start point and end point of the section are specified. The "start cell ID" and "end cell ID" of the section marker in FIG. 9 specify cell information # 1 and cell information # 3 as indicated by arrows sr1 and sr2. From the cell information designated by the start cell ID and the end cell ID and "indirect reference to indirect reference" via the access map, it can be seen that the start point and end point of the extended attribute section are designated. Arrows rr1, rr in the figure
2 symbolizes this "indirect reference to indirect reference". The start point ty1 and end point yn1 of the extended attribute section having the unviewed attribute due to this "indirect reference to indirect reference"
It can be seen that is specified by the section marker.

FIG. 10 is a diagram showing a section marker for designating an extended attribute section having an unviewed attribute with respect to the reproduction path of the user B. It is assumed that the middle position ty2 of a part and the end position yn2 of a part in the figure are the start point-end point of the extended attribute section having the unviewed attribute. The section marker in the PGC information # 2 specifies the start point and end point of the extended attribute section that the user B has not yet viewed by "indirect reference to indirect reference". According to the section marker in the figure, the "start cell ID" and "end cell ID" of the section marker are the cell information # in the PGC information.
4, cell information # 5 is designated as indicated by arrows sr3,4.
The start point-end point of the extended attribute section is designated by "indirect reference to indirect reference" via the cell information # 4 and cell information # 5 in the PGC information and the access map in the VOB information. Arrows rr3 and rr4 in the figure symbolically indicate this "indirect reference to indirect reference".

By providing a section marker in the PGC information, it is possible to set an extended attribute section according to the individuality, commitment and convenience of each user for the playback path for each user. The above is the application by providing the section marker in the PGC information. In the section marker in the PGC information, end point information indicating the end point,
It is not essential to use the end cell ID that indicates the cell where the end point is located. You can omit this or use another parameter (VOB
The end point of the extended attribute section may be represented by using an equivalent number such as the number of Us or the number of picture data. It is desirable to strictly specify the start point of the unreproduced section where the user stopped viewing when the section that the user has not yet viewed is specified as the extended attribute section, but the end of the extended attribute section. Because the point coincides with the end point of the playback path defined by the user, it is often implicitly set.

Next, an application in the case of providing a section marker in VOB information will be described. FIG. 11 is a diagram showing VOB information in which a section marker is incorporated. Hatched parts ht1, ht2 in this figure
Has a CM attribute and is recognized as an extended attribute section
It is a part of TS-VOB. The reason for recognizing the CM attribute may be a voice attribute or designation by the user, but it does not matter here. When users A and B uniformly want to skip the recognized extended attribute section, this CM is applied to the playback paths of users A and B.
There is a desire to specify extended attribute sections that have attributes. Where in the reproduction path for the user A and the user B the CM section exists is as shown by the arrows in the figure. Position yf1 to position yf2, position yf3 to position yf4 in the reproduction path for user A, and position yf5 to position yf6, position yf7 in the reproduction path for user B.
There is a CM section from to position yf8. The section marker in the VOB information realizes the collective designation of the extended attribute section for all users who refer to TS-VOB # 1. In this figure, TS
-Directly written arrows toward VOB, dr1 and dr2 are V
It symbolically represents batch designation by section markers in OB information. In other words, the direct arrows dr1 and dr2 have the combined meaning of specifying the extended attribute section for the reproduction path of the user A and specifying the extended attribute section for the reproduction path of the user B. Arrows yf1, yf2, yf3, yf4 indicate designation of extended attribute sections for the reproduction route of user A, and arrows yf5, yf6, yf7, yf8 indicate designation of extended attribute sections for the reproduction route of user B. The collective designation symbolized by the arrows dr1 and dr2 has the same meaning as a bundle of designations of extended attribute sections for a plurality of reproduction paths. By realizing the simultaneous designation of the reproduction paths of each user, the notation of the section marker can be made simple and easy to understand.

What about a portion which is specified as an extended attribute section by the section marker in the VOB information but is not defined as a reproduction path by the reproduction path information? In the example of FIG. 11, the portions indicated by the broken lines hh1 and hh2 are specified as extended attribute sections by the section markers in VOB information # 1 and # 2, but the playback path defined in VOB information # 2. Is a part that does not belong to. VOB information # 1, # 2
The section designation by the section marker does not extend to the portions indicated by the broken lines hh1 and hh2. This means that with respect to the superiority or inferiority of the section marker in the VOB information and the reproduction path defined by the reproduction path information, the reproduction path defined by the reproduction path information has priority. That is, even if the section marker in the VOB information specifies the extended attribute section, if it is not defined as the reproduction path by the reproduction path information, the reproduction control or the expansion control is not performed at this location.

A description will be given of what kind of reproduction control is performed on the two reproduction paths to which the extended attribute section is designated all at once. FIG. 12 shows a reproduction path for user A,
FIG. 6 is a diagram showing what kind of extended control is performed with a reproduction path for user B. The horizontal arrows yc1,2,3 in the figure are
A symbolic representation of the raw processing along the playback path
cv1, 2, and 3 symbolically indicate skip processing at the time of reproduction by user A and user B. Since skip processing is performed in the CM section during playback by user A and user B, skipping in the CM section is uniformly performed by specifying the extended attribute section having the CM attribute with the section marker. You can see that It is the same as the PGC information in that it is not essential to use the end point information indicating the end point in the section marker in the VOB information. This may be omitted, or another parameter (equivalent one such as the number of VOBUs or the number of picture data) may be used to represent the end point of the extended attribute section.

Next, how the section start point is represented by the section marker start point information will be described. The start point information in the section marker in the VOB information indicates the location of the start point of the extended attribute section with a time accuracy equal to or lower than the video frame of the picture data in TS-VOB corresponding to the section marker. As a result, the location where extended control is desired to be performed is represented in detail by the section marker in the VOB information.

On the other hand, the start point information in the section marker in the PGC information also indicates the location of the start point of the extended attribute section with a time accuracy equal to or lower than the video frame of the picture data in TS-VOB. This TS-VOB is a TS-VOB corresponding to the cell designated by the start cell ID of the section marker. As a result, the location where the extended control is desired to be performed is represented in detail by the section marker in the PGC information.

The time accuracy below this video frame is 1 /
Time accuracy of 27,000,000 seconds and 1 / 90,000 (= 300 / 27,000,00
It is desirable to express it in combination with the time accuracy of 0) seconds. 1 / 90,000 second time accuracy is NTSC signal, PAL signal, Dol
ByAC-3, taking into account the common multiple of the frame frequency of MPEG audio, the time accuracy of 1 / 27,000,000 seconds is specified in consideration of 27 MHz which is the clock frequency on the playback device side.

The extended attribute section designated by the section marker in the VOB information is a CM section where it is desired to uniformly perform the extended control of "skip" to each user. A certain section may be designated as an extended attribute section having extended control of "skipping". For example, when playing TS-VOB, parents discover sexual scenes and violence scenes. If you decide you don't want to show these to others in your family, VO
A section marker is provided in the B information and these scenes are designated as the extended attribute section. By doing so, these scenes can be skipped during reproduction by all users. Further, the extended control to be performed in the CM section is the extended control called "skip", but, for example, the URL of the sponsor company related to the CM section is displayed overlappingly on the CM section, or the sponsor company is displayed. There is one that displays a logo mark related to thumbnails.

Further, the extended attribute section designated by the section marker in the PGC information is an unviewed section to which the extended control of "cue" is to be performed.
The section to which the fast forward / rewind is performed in the past by the user B may be designated as the extended attribute section. Thereby, it is possible to easily realize the extended control of repeating the same processing in these extended attribute sections.

Although one section marker is provided in one PGC information in this embodiment, a plurality of section markers may be provided. The extended attribute sections designated by the plurality of section markers may overlap each other.
Similarly, the number of section markers provided in one VOB information is one, but this may be plural. The extended attribute sections designated by the plurality of section markers may overlap each other.

(Second Embodiment) This embodiment is an embodiment relating to the recording apparatus 100 for the TS-VOB according to the first embodiment. The recording apparatus 100 mainly executes the recording process for the TS-VOB, but can perform the reproducing process for the TS-VOB. In other words, it is a hybrid type recording device 100 having both the functions of the recording device 100 and the reproducing device. FIG. 13 is a diagram showing the internal configuration of the recording apparatus 100. The components shown in this figure are:
(i) those used for both recording and playback, (ii)
It is classified as either one used only for recording processing or (iii) only used for reproduction processing.

First, the components used in both the recording process and the reproducing process will be described. Such components include the user interface unit 2, the drive device 3, the resident memory 4, and the track buffer 5. The user interface unit 2 receives an operation for instructing special reproduction such as recording of a broadcast program, selection of reproduction path information recorded on a DVD, reproduction, fast forward, and rewind from the user via a remote controller or a panel button.

The drive device 3 is provided with a base for setting a DVD, a spindle motor for clamping and driving the set DVD to rotate, an optical pickup for reading a signal recorded on the DVD, and an actuator for the optical pickup. Access to. The access to the DVD includes writing the VOBU at the time of recording the program and reading the VOBU at the time of the reproduction.

The resident memory 4 is a memory for resident VOB information and PGC information. The VOB information and the PGC information are made to reside in this memory in order to avoid a conflict between the disk access (a) for recording the VOBU and the disk access (b) for updating the management file. VOB
The V stored in the resident memory 4 when the recording of U was completed
The OB information and PGC information are written back to the DVD.

The track buffer 5 is a buffer for temporarily storing VOBUs to be written on the DVD and VOBUs read from the DVD. V to burn on DVD
The VOBU read from the OBU or DVD is stored in the track buffer 5 in order to absorb the speed difference between the decoding speed of the decoder 16 and the reading speed of the DVD from the drive device 3, and the encoder 7 The purpose is to absorb the speed difference between the encoding speed due to and the writing speed to the DVD by the drive device 3.

The components described above are commonly used for the recording process and the reproducing process. Next, the components used in the recording process will be described. This component includes an analog tuner 6, an encoder 7, a digital tuner 8, an extraction unit 9, an analysis unit 10, a map creation unit 11, an extended attribute section detection unit 12, a CM section detection unit 13, and a reproduction path information creation unit 1.
4. There is a recording controller 15.

The analog tuner 6 obtains an analog broadcast signal corresponding to a single program by modulating the broadcast wave transmitted from the broadcast station and selecting the channel. The encoder 7
VOBU is obtained by encoding the signal section of the analog broadcast signal corresponding to a single program output from the analog tuner. The encoder 7 includes a video encoder (1) that obtains a GOP by encoding a video signal in an analog broadcast signal, an audio encoder (2) that obtains an audio data string by encoding an audio signal in the analog broadcast signal, And a multiplexing unit (3) for multiplexing GOP and audio data to obtain VOBU. Each time a GOP is generated, the encoder 7 outputs the reproduction time of the VOBU and the data length of this VOBU to the map creation unit 11.

The digital tuner 8 obtains a digital broadcast signal corresponding to a single program by modulating and selecting a broadcast wave broadcast from a broadcast station. In the present embodiment, the recording device 100 obtains the digital broadcast signal by incorporating the digital tuner 8 therein, but the digital broadcast signal may be obtained from the digital tuner 8 incorporated in a separate device such as STB (SetTopBox). .. In this case, the recording device 100 must be provided with a digital interface for receiving the input of the digital broadcast signal from the STB.

The extraction unit 9 extracts a TS packet sequence from the signal section of the digital broadcast signal and adds ATS to each TS packet to obtain VOBU. The analysis unit 10 includes the extraction unit 9
It is a component implemented within the device and determines which TS packet includes the head of the access point by referring to the random access indication flag in the applicable field of the TS packet. Furthermore, by referring to the unit start indicator of the TS packet, the TS
Detects detection of access points in packets.
The determination process and the detection process are repeated for a plurality of TS packets, and then the VOBU size and the VOBU playback time are calculated. The size of the VOBU is obtained by calculating the difference from the start position of the access point to the start position of the subsequent access point. The VOBU playback time is obtained by calculating the difference from the PTS at the start position of the access point to the PTS at the start position of the subsequent access point. The VOBU size and the reproduction time thus obtained are output to the map creation unit 11.

The map generator 11 calculates the VOBU size and playback time output from the encoder 7 and the analyzer 10.
Entry information about the VOBU is obtained in association with the VOBU identifier, and written in the resident memory 4. An access map can be obtained by repeating the entry information generation process for each VOBU included in the TS-VOB.

When the content of the extension control performed at the time of reproduction is CM skip and it is uniformly valid in a plurality of reproduction paths, the extension attribute section detection unit 12 determines the section in which the extension control is to be performed by the plurality of reproduction path information. The multiple reproduction paths shown are collectively designated as shown in FIG. In order to realize such collective designation, the extended attribute section detection unit 12 creates a section marker indicating where the collectively designated extended attribute section exists in the TS-VOB,
Included in VOB information. Creation of the section marker here is performed by the following processing. The extended attribute section detection unit 12 monitors what kind of attributes the signal sections forming the digital broadcast signal and the analog broadcast signal have. If there is a change in attributes, respond to that change point
Detect the position on TS-VOB. Such a change point is considered to be the position where the extended control should be started, that is, the start point of the extended attribute section. Therefore, create a section marker that specifies the extended attribute section with this change point as the start point, and add the VOB information. Built in. When creating the section marker, the extended attribute section detection unit 12 uses the encoder 7 at the time of detection.
And P of the PES packet input to the extraction unit 10 or PES packet output from the encoder 7 and the extraction unit 10.
The change points are expressed using TS.

The CM section detection unit 13 is a component mounted in the extended attribute section detection unit 12, and a signal section having a stereo voice attribute is inserted in the middle of a broadcast signal having a monaural voice attribute. If so, the position on the digital stream corresponding to the change point from analog audio to stereo audio is detected. Such a change point is considered to be the position where the extended control called "CM skip" should be started, that is, the start point of the extended attribute section having the CM attribute. Therefore, specify the extended attribute section with this change point as the start point. Create a section marker to be included and incorporate it in the VOB information.

The reproduction path information creating unit 14 is a TS-VO for DVD.
When the writing of B is completed, any of the T-VOB constituent T
Select the S packet as the start point of the cell, select another TS packet that composes the TS-VOB as the end point of the cell, and create the cell information with the PTS attached to these as the start point information and the end point information. . Reproduction of cell information is repeated, and the generated cell information is arranged in the memory to obtain reproduction path information, and PGC information including the reproduction path information is generated. If the reproduction path is defined by the user, the work of selecting the start point and the end point of the cell is performed according to the user operation accepted by the user interface unit 2.

The recording control section 15 realizes writing control on the premise of buffering by the track buffer 5. This writing control is performed by the encoder 7 or the extraction unit 9
With the TS packet output from, the track buffer 5
Is waited for, and if so, the multiple TS packets in the track buffer 5 are written to the ECC block of the DVD. If the user performs a recording end operation, it has been accumulated in the track buffer 5 by then.
The TS packet is written in the ECC block of the DVD, the VOB information and PGC information stored in the resident memory 4 are written in the DVD, and the recording process ends.

The above are the components that realize the recording process in the recording apparatus 100. Next, components of the recording device 100 that implement the reproduction process will be described.
Such components include the decoder 16 and the reproduction controller 1.
7, an extended attribute section setting unit 18, and an unviewed section detection unit 19. The decoder 16 is a demultiplexing unit (1) that separates the VOBU read from the DVD by the drive device 3 into a video data string and an audio data string, a video decoder (2) that decodes the video data, and an audio decoder that decodes the audio data. It is equipped with (3), and outputs an AV signal, which is a video-audio multiplexed signal, to the television.

The reproduction control unit 17 obtains the address on the DVD of the TS packet which is the starting point of the cell by indirect reference using the access map as the reference table.
The same indirect reference is performed for the TS packet that is the end point of the cell, and the address of the TS packet that is the end point of the cell on the DVD is obtained. If the addresses on the DVD of the TS packets corresponding to the start point and the end point are calculated, the drive device 3 is instructed to read between the addresses and the decoder 16 is instructed to decode the read TS packets. .
If such reproduction control is performed for a plurality of pieces of cell information forming the reproduction path information, reproduction control according to the reproduction path information is realized. The above playback control is basic, and by performing irregular VOBU reading,
The recording device 100 realizes special reproduction. For example all TS
Fast-forwarding can be realized by reading out multiple VOBUs in sequence instead of reproducing packets. Further, rewinding can be realized by reading out a plurality of VOBUs in the reverse order of the arrangement of TS packets in TS-VOB.

The extended attribute section setting unit 18 indicates that the content of the extended control performed during reproduction is reproduction of an unviewed section, etc.
When it is effective only within the reproduction path indicated by one reproduction path information, the section for which the extended control is to be performed is individually specified for the reproduction path. In the individual designation, a section marker indicating where the designated section exists is created and incorporated into the PGC information. The section marker is created as follows. The extended attribute section setting unit 18 monitors what operation is performed by the user during playback control based on the playback path. When an operation is detected, the detected position on the digital stream is detected as the position to start the extended control, and the section marker that specifies the extended attribute section starting from the start position is added to the PGC information. Create in. When creating a section marker, the extended attribute section setting unit 18
Expresses the detection point using the PTS of the PES packet input to the decoder 16 when the operation is detected.

The unviewed section detecting unit 19 is a component mounted in the extended attribute section setting unit 18, and monitors what operation is performed by the user during reproduction control based on the reproduction path. When a stop operation is detected, the position on the detected digital stream is detected as the position to start the expansion control, and the start position is set as the start point, and the end of the reproduction path is set as the end point. Create a section marker that specifies the attribute section in the PGC information, and
Included in GC information. Since the unviewed section detection unit 19 detects the unviewed section, the unviewed section detection unit 19 detects the extended attribute section each time the user plays the playback path and stops playing the playback path. The detection and the creation of the section marker are repeated. The reason why the extended attribute section detected by the unviewed section detection unit 19 is set as the "unviewed" section instead of the "unplayed" section is that the section other than the section played by the user is also included. When the user is recording while watching a broadcast program and quits watching during the recording, the portion from the position where the watching is stopped to the end of the reproduction path is detected as an unviewed section. For example, when the user is recording while watching a broadcast program and quits watching during the recording, the unviewed section detection unit 19 detects an operation indicating that the viewing is to be stopped, such as power-off of the TV, and the like. It suffices to detect from the time when the operation is detected to the end of TS-VOB as an unviewed section.

The above are the components of the recording apparatus 100.
These components are realized by a program and a computer that decodes and executes the program. Figure 1
4 and 15 are flow charts showing the procedure of this program, and while referring to this flow chart,
The process performed by the recording device 100 will be described in more detail. still,
For the sake of simplification of the following description, the extended attribute sections to be detected / set are limited to two sections, the CM section and the unviewed section.

The loop process consisting of steps S1 to S3 in the flowchart of FIG. 14 is located in the highest layer of the process, and realizes the distribution to various processes according to the operation performed by the user. When a recording operation is performed, this operation is detected by the user interface unit 2 and the process proceeds from step S3 to step S4. In step S4, the recording controller 15
Detects and stores the audio attribute of the signal section of the analog broadcast signal as a default audio attribute, and resets Flag described later to 0. Then, in step S5, the recording control unit 15 instructs the encoder 7 to encode the sequentially input signal sections, and then in step S6.
Then, the process proceeds to the loop process including step S7. This loop processing causes the CM section detection unit 13 to continuously detect a change in the audio attribute of the signal section while the analog broadcast signal is continuously input. The requirement for ending this loop processing is that step S7 is determined to be Yes. Further, every time a change in the voice attribute of the signal section is detected, the processing of steps S6 to S7 via the processing of steps S8 to S14 is repeated.
In steps S8 to S14 passed here, the CM section detection unit 13 sets the change point as a start point or an end point of the extended attribute section, and steps S8 to S14.
After setting the start point or end point in step S14, the process returns to the loop process of steps S6 to S7.
That is, while the analog broadcast signal is continuously input and the recording process is continued, each time the voice attribute change point is detected, the CM section detection unit 13 starts the extended attribute section,
The end point is set. In steps S9 and S12, the CM section detection unit 13 detects the PTS of the TS packet input to the encoder 7 when the audio attribute of the analog broadcast signal changes. The change point of the voice attribute is represented by this PTS. Switching between the change point as the start point and the end point is performed by the value of Flag. If Flag is 0, the CM section detection unit 13 sets the detected PTS as the start point of the extended attribute section having the CM attribute in step S10, and then in step S10.
In 11, the Flag is set to "1". If Flag is 1,
In step S13, the CM section detection unit 13 determines the PTS to be the CM
The flag is reset to "0" at step S14 after the start point of the extended attribute section having the attribute.

If the user performs an operation for instructing to stop the recording process, the process proceeds from step S7 to step S16. In step S16, the recording controller 15
The VOB information including the section marker indicating the location of the extended attribute section having the CM attribute and the PGC information including the reproduction route information indicating the default reproduction route in the TS-VOB are generated in the resident memory 4, and the step is generated. VOB in S17
Write information and PGC information to DVD.

The above is the processing at the time of recording. As a result, the TS-VOB, VOB information, and PGC information are recorded on the DVD. When an operation for instructing execution of reproduction is performed, the loop processing including steps S1 to S3 is changed to steps S18 to S22 shown in FIG. The loop process including steps S18 to S22 receives various operations from the user for defining the reproduction path information by the user. If a reproduction operation is ordered (Yes in step S18), the reproduction controller 17 orders the drive device 3 to execute a disk access for normal reproduction in step S18. As a result, the reproduced video of TS-VOB will be displayed on the TV. When an operation for performing fast forward / rewind is performed (Yes in step S19), the recording control unit 1 is operated in step S24.
Reference numeral 5 causes the drive device 3 to execute disk access for realizing fast forward / rewind. By the above operation, the cueing to the place to be set as the cell is realized at high speed.
When the operation of specifying the start point is performed (step S
(Yes in 20), and in step S25, the reproduction path information creation unit 14 detects the PTS of the TS packet output from the decoder 16 and sets this as the start point of the cell information.
On the other hand, when the operation of designating the end point is performed (Yes in step S21), the reproduction path information creation unit 14 outputs the TS output from the decoder 16 in step S26.
The PTS of the packet is detected and this is used as the end point of the cell information. By repeating the above process, a plurality of pieces of cell information, which are constituent elements of the reproduction path information, can be obtained in the resident memory 4. If the stop operation is performed, step S22
If Yes, the PGC information including the reproduction path information formed by arranging the cell information created in step S15 is written on the DVD.

TS via user defined playback path information
-VOB reproduction processing will be described. Since this reproduction path information is composed of a plurality of cell information, the cell information targeted in steps S27 to S33 is set to the variable j.
Instruct. Steps S27 to S30 constitute a loop process using this variable j as a control variable. The reproduction control unit 17 determines that j
The second cell information is taken out (step S28), and the drive device 3 is instructed to read the VOBU from the start point to the end point of the cell information j (step S2).
9), the VOBU thus read is decoded by the decoder 16
Is decoded to output video. This increment of the control variable is performed in step S31. Also, the termination requirement for this loop processing is step S
In 30, it is determined that the control variable reaches the total number of cells, or it is determined that the reproduction end operation is performed by the user.

When the stop operation is performed, the process proceeds from step S30 to step S32, and the unviewed section detecting unit 19 moves to the end of the reproduction path information from the next TS packet input to the decoder in the cell j. The section marker that specifies up to the end point of the cell information as an extended attribute section having an unviewed attribute is created, and the section marker created in step S33 is used as a user-defined PG.
Include in C information. Through the above processing, the extended attribute section having the unviewed attribute is set to the user-defined reproduction path.

As described above, according to the present embodiment, the recording apparatus 100 having the configuration shown in the present embodiment causes the DVD shown in the first embodiment to be generated. It can promote the spread. (Third Embodiment) In the third embodiment, if the section marker in the PGC information defines an extended attribute section having an unviewed attribute, how to specify the location of the extended attribute section on the DVD. I will explain. In the access map in the VOB information, the playback time for each VOBU and the size are described in association with each other, so if the addresses and playback times described here are integrated, the start point of the extended attribute section, The VOBU including the end point can be specified. When the start point and the end point of the extended attribute section exist in the same cell, it is sufficient to read from the VOBU including the start point thus specified to the VOBU including the end point. The problem here is that the start point and the end point are in different cells. FIG. 16A shows two consecutive cells (cell # 1,
An example in which the start point and the end point of the extended attribute section exist in cell # 2) is shown. In this case, for the preceding cell # 1, it is necessary to read from the start point rp1 of the extended attribute section to the end point rp2 of the cell # 1. For the subsequent cell # 2, it is necessary to read the VOBU from the beginning rp3 of cell # 2 to the end point rp4 of the extended attribute section. That is, if the extended attribute section includes a boundary between cells (end point-start point pair), VOBU from the start point of the extended attribute section to the end point of the cell, the start point of the subsequent cell to the extended attribute section VO to end point
Like BU, VOBU is read twice.
FIG. 16B shows an example in which the start point and the end point of the extended attribute section are present in the end cells (cell # 1 and cell # 5) in three or more consecutive cells. In this case, for cell # 1, from the start point rp5 of the extended attribute section to the end point r of cell # 1
VOBUs up to p6 must be read. For cell # 5, the VOBU from the start point rp7 of cell # 5 to the end point rp8 of the extended attribute section must be read. For the cells # 2 to # 4 which are interposed between the cell # 1 and the cell # 5, all VOBUs located from the start point to the end point are read. If the above-mentioned reading is performed on the cells # 1 to # 5, the VOBU including the extended attribute section is read.

As described above, according to the present embodiment, even if the location of the extended attribute section is indicated in "indirect reference to indirect reference", it is necessary to reproduce from where to where in the TS-VOB. It is possible to easily specify the starting point of Kika. (Fourth Embodiment) The present embodiment discloses a process in the case where the extended control based on the section marker set in the PGC information and the extended control based on the section marker set in the VOB information are both executed. FIG. 17 is a diagram showing an internal configuration of the reproduction control unit 17 according to this embodiment. The reproduction control unit 17 in this embodiment includes an extended control execution unit 20 and an extended control arbitration unit 21.

The extended control execution unit 20 performs extended control unique to the extended attribute section specified by the section marker in the VOB information and PGC information. The extended control arbitration unit 21 performs an arbitration process so as to avoid the competition between the extended controls that may occur in the overlapping portion between the extended attribute sections. The arbitration by the extended control arbitration unit 21 is
Based on the extended attribute for the extended attribute section, priority is set for the extended control for each extended attribute section, and the extended control with lower priority is not executed. Instead, extended control with higher priority is exception. It is to be carried out in a targeted manner.

FIG. 18 shows an example in which an unviewed section has an overlapping portion with an extended attribute section (CM section) having a CM attribute. In this case, the extended control arbitration unit 2
If 1 performs arbitration between the extended controls, it becomes as follows. When the extended attribute section that is an unviewed section and the extended attribute section that is a CM section overlap, a priority order is set for the extended control. If the priority of the extended control of "skip CM segment" is higher than that of the extended control of "reproduce unviewed segment", replace the extended control of "reproduce unviewed segment" for this overlapping part. Then, the extended control of "skipping the CM section" is executed as shown by arrow cy1. On the other hand, of the unviewed section, the non-overlapping part with the CM section is expanded control unique to the unviewed section, that is, the arrow.
As shown in cy2 and cy3, extended control is performed to reproduce the unviewed section as it is. How to set the priority for each extended attribute section will be described. In the present embodiment, the priority order of the extended attribute section specified by the section marker in the VOB information is
Set higher than the priority of the extended attribute section specified by the section marker in the PGC information. The reason is as follows. The extended attribute section specified by the section marker in the PGC information is determined based on the user's operation, and is often the content of the user only. On the other hand, the extended attribute section specified by the section marker in the VOB information often has universal value for all users. In this way, the extension control, which has universal value, is prioritized over the extension control for the user, and the extension control is integrated.

In the overlapping portion, the arbitration by the extended control arbitration unit 21 is necessary when the extended control peculiar to the extended attribute section has an exclusive relationship with each other, and if the extended control peculiar to the extended attribute section can coexist. The arbitration by the extended control arbitration unit 21 is unnecessary. For example, if the extended control for the extended attribute section having the CM attribute is non-exclusive such as overlapping display of URL and thumbnail display of logo mark, it may be performed in parallel with other extended control. The extended control arbitration unit 21 also refers to the section information of the section marker to determine whether extended control can coexist and whether arbitration should be performed.

The extended control arbitration unit 21 is composed of a program that realizes the flowcharts of FIGS. 19 and 20, and a processor that decodes and executes the program. 19,
FIG. 20 is a flowchart showing a processing procedure of the extended control arbitration unit 21 according to this embodiment. Although this flowchart basically performs the extended attribute section that plays back the unviewed section, if the unviewed section overlaps with the CM section, the process of skipping this CM section is an exception. This is what you do. In order to simplify the following description,
The extended attribute sections that should be detected and set are limited to the CM section and the unviewed section.

After the cell i including the start point and the cell j including the end point of the extended attribute section having the unviewed attribute are specified in step S40, step S41 is executed. Step S41 is a step of determining whether or not cell i matches cell j. The fact that cell i matches cell j means that the unviewed section is included in one cell.

If the cell i and the cell j match, in step S43, from the start point of the extended attribute section having the unviewed attribute in the cell i to the end point of the extended attribute section having the unviewed attribute. You can play. However, we must not forget that this unviewed section may overlap with the CM section. Step S42 is a determination step of determining the presence or absence of this duplication, and if the start point of the CM section exists,
Exceptionally, the playback of the unviewed section is stopped before and after this. That is, in step S44, the reproduction is started from immediately after the start point of the extended attribute section having the unviewed attribute to immediately before the extended attribute section having the CM attribute, and then in step S45, the CM is reproduced.
Immediately after the extended attribute section having the attribute, to the end point of the extended attribute section having the unviewed attribute is reproduced. After the above reproduction control is completed, the processing of this flow chart is completed.

On the other hand, if cell i does not match cell j, in step S47, reproduction is performed from the start point of the extended attribute section having the unviewed attribute in cell i to the end point of cell i, and step S48. In the following, the cell next to cell i is designated as cell i. These steps S47 and S48
There is also exception processing when the unviewed section overlaps the CM section. Step S46 is a step of determining whether or not this exceptional processing is necessary, and it is determined whether or not the start point of the extended attribute section having the CM attribute is included inside the cell i. If the start point of the CM section exists in cell i, this exception processing is executed. The exception process when step S46 determines that there is duplication is the main part of the process of reproducing before and after the CM section, but in addition to this, there is also the process of skipping the part corresponding to the CM section.

That is, in step S49, after the reproduction from the start point of the extended attribute section having the unviewed attribute to immediately before the CM attribute section is reproduced, in the next step S50, the extended attribute section having the CM attribute ends. Identify which cell the point is inside. The cell including the end point of the CM section is specified in this way because the cell including such end point does not always match the cell i. If the cell including the end point of the extended attribute section having the CM attribute is the cell k, the cell k is reset to the cell i in step S51. By such reconfiguration, cells from cell i to cell k are skipped. Finally step S
At 52, reproduction is performed from immediately after the extended attribute section having the CM attribute to the end point of the extended attribute section having the unviewed attribute, and the exception processing is ended.

When the processes of steps S48 and S52 are completed, steps S53 to S56 of FIG.
To the loop processing consisting of. "I" of the cell i plays a role of the control variable in this loop processing, and the reproduction of the cell i specified by this i is performed in step S55. It is step S53 that defines the termination requirement for this loop processing. This step S53 is for cell i
It is determined whether or not there is an end point of the extended attribute section having the CM attribute, and if there is, the loop processing is exited and the process proceeds to step S57.

Step S54 is a switching step for executing exceptional processing when the start point of the CM section exists in cell i. During execution of this exception handling, the variable i
Does not increment by one, but skips to the cell where the end point of the CM section exists. That is, in step S61, playback is performed from the start point of cell i to immediately before the extended attribute section having the CM attribute, and then in step S61.
At 62, the cell k including the end point of the extended attribute section having the CM attribute is specified. In step S63, cell k is updated to cell i. If many cells are skipped, cell i may reach the end point of the unviewed section. In step S64, it is determined whether the end point of the unviewed section is reached, and specifically, it is determined whether or not the cell i includes the end point of the extended attribute section having the unviewed attribute. The inclusion of this means that the requirement for ending the loop processing described above is satisfied, and thus step S53
Without waiting for the requirement in step S66 to be satisfied
At, the process is finished after reproducing from immediately after the extended attribute section having the CM attribute to the end point of the extended attribute section having the unviewed attribute.

If it is not included, the reproduction is performed from immediately after the extended attribute section having the CM attribute to the end point of the cell i in step S65, and then steps S53 to S56.
Return to the loop processing consisting of. By repeatedly executing this loop process, cells that do not include the end point are sequentially reproduced in the unviewed section. After ending the loop process including steps S53 to S56, the process proceeds to step S57. In step S57, it is determined whether or not the start point of the extended attribute section having the CM attribute exists in the cell including the end point of the unviewed section. If the start point is not included, reproduction is performed from the start point of the cell i to the end point of the extended attribute section having the unviewed attribute in step S58.

If the start point is included, step S59
From the start point of cell i to immediately after the extended attribute section having the CM attribute, in step S60, from immediately after the extended attribute section having the CM attribute to the extended attribute section having the unviewed attribute. Play to the end point. As described above, according to the present embodiment, it is possible to suitably realize the combination of the extended control that respects the viewing preference of each user and the extended control that is universally necessary for a plurality of users. You can increase.

(Fifth Embodiment) This embodiment relates to an improvement for dealing with subdivision and detailing of section markers. It is hard to say that the standard of the extended attribute, which is the extended attribute in the reproduction path, is greatly influenced by the intention of the manufacturer who manufactures the recording device 100 and the product strategy, and is not standardized. It is considered that the segmentation and detailing will continue in the future. The present embodiment discloses a DVD capable of suitably managing the section markers thus subdivided and detailed.

FIG. 21 shows PGC information and V according to the present embodiment.
It is a figure which shows the internal structure of OB information. The section marker in this figure is different from the section marker shown in the first embodiment in that "section information" is newly provided. The section information in the present embodiment indicates whether the section marker belongs to a section that is valid among a plurality of manufacturers or belongs to a section that is valid only by a single manufacturer. FIG. 22
FIG. 6 is a diagram showing setting contents of classification information. When the section marker belongs to the former category, "maker common code" is set in the category information. When the section marker belongs to the latter category, the category information is set with the "maker-specific code" and the "maker ID" for the manufacturer.

The case where the section marker is valid among a plurality of manufacturers means that there is agreement of a plurality of manufacturers participating in the disk standard in the agreement of the standard of the extended attribute section corresponding to the section marker. The recording device 100 manufactured by a manufacturer participating in the disc standard promises to perform common extended control for the extended attribute section indicated by the section marker.

When it is effective between independent manufacturers, the standard arrangement of the extended attribute section corresponding to the section marker is based on the sole discretion of one manufacturer and participates in the disk standard. This means that the recording apparatus 100 manufactured by another manufacturer does not need to perform extended control for the extended attribute section indicated by the section marker. In this case, since it is necessary to indicate which manufacturer of the recording apparatus 100 the section marker is effective in, the above-mentioned manufacturer ID is used together.

At the time of reproduction, the recording apparatus 100 refers to the manufacturer ID in the section marker included in the VOB information and PGC information, and is a section marker that is effective in a single manufacturer, and this manufacturer ID is its own manufacturer ID.
Extended control based on this section marker is performed only for the section marker that matches with. For a section marker that is effective in a single maker and has a built-in maker ID different from that of the recording device 100, extended control based on the section marker is not performed.

Subsequently, the recording apparatus 100 according to the present embodiment.
The internal configuration of will be described. FIG. 23 is a diagram showing an internal configuration of the recording device 100 according to the present embodiment. The recording apparatus 100 according to the present embodiment is the same as the conventional recording apparatus 1
The difference from 00 is that a maker ID holding unit 23 is newly added, and the recording control unit 15 and the reproduction control unit 17 perform the processing unique to this embodiment.

The maker ID holding unit 23 holds an identifier unique to the maker who manufactured the maker ID. Recording controller 15
Is, when creating a section marker, determines what type of extended attribute section the extended attribute section specified by the section marker has, and
Obtaining classification information indicating the determination result. It is determined whether the type of the extended attribute section is valid among multiple makers or is valid with a single maker, and if the type is valid with a single maker, the manufacturer held by the recording control unit 15
Include the ID in the classification information.

When executing the extension control, the reproduction control section 17 refers to the section marker designating the location peculiar to the extension attribute section. If the section marker division information indicates "valid between multiple makers", extended control unique to the extended attribute section designated by the section marker is executed. If the section information of the section marker indicates “valid for a single maker”, the maker ID included in the section marker is taken out and compared with the maker ID held by the maker ID holding unit 23. If both maker IDs match, extended control is executed for the extended attribute section specified by the section marker, and if they do not match, it is not executed.

As described above, according to the present embodiment, the section marker effective in a single maker is:
The manufacturer ID for the manufacturer is embedded inside the section marker. By referring to this, it is possible to perform a process of ignoring a section marker which is set by another company independently during reproduction. As a result, it is possible to avoid a malfunction caused by an attempt to perform processing according to a standard independently set by another company.

(Sixth Embodiment) The present invention relates to an improvement in the case of performing long-time recording on a DVD having a maximum recording capacity of 27 GB or more on one side. Such a large-capacity DVD is 1 for NTSC broadcasting.
It is possible to record broadcast contents for more than 3 hours. Take D
With the advent of VD, half-day and one-day programs broadcast on a certain channel can be recorded as one TS-VOB on one DVD and shared by many users such as family members and multiple friends. It is expected that a multi-user usage method of viewing and listening will be established in the future. But in this case, half a day,
Among TS-VOBs corresponding to one-day broadcast contents, each user needs to find out where the program he / she wants to watch exists by making full use of special playback such as fast-forward. Salmon roe
Even though the fast-forward process on DVD is performed at high speed, such a searching operation is quite troublesome.

Therefore, the extended attribute section detection unit 12 according to the present embodiment detects a portion of TS-VOB corresponding to one program as an extended attribute section, and creates a section marker designating this in the VOB information. . FIG. 24 is a diagram showing an internal configuration of the extended attribute section detection unit 12 according to the sixth embodiment. As shown in the figure, the extended attribute section detection unit 12 has a program sequence change section in addition to the CM section detection unit 13. The detector 24 and the carousel section detector 25 are provided.

The program arrangement change section detecting unit 24 detects, as an extended attribute section, a section of the digital broadcast signal in which the program arrangement information has changed to a specific one (referred to as a section in which the program arrangement information has changed). The PSI (Program Spesfic Informat) is used to detect the extended attribute section by the program arrangement change section detection unit 24.
in: Program arrangement information in the MPEG2 standard), SI (Service Info
rmation: ARIB-STD B-10). PSI is information that defines the arrangement of programs, such as PAT and PMT. PMT is information that defines the stream structure of a broadcast program. That is, the PMT indicates which of the video stream and the audio stream that make up each broadcast program among the multiple streams that are multiplexed into the multi-program type transport stream. FIG. 25A is a diagram showing an example of PMT, and the broadcast program corresponding to PMT # 1 in this figure is a PID.
It can be seen that it is composed of a video stream having = 001 and an audio stream having PID = 002. PAT
Indicates which PMT should be referred to to acquire each broadcast program transferred by the multi-program type transport stream. FIG. 25B is a diagram showing an example of PAT. In this figure, it can be seen that the stream structure of the broadcast program # 1 is shown in PMT # 1 and the stream structure of the broadcast program # 2 is shown in PMT # 2. These PMTs on the broadcast channel being received by the tuner,
By referring to the PAT IDs, it is monitored where these IDs have reached predetermined values and where they have changed from the previous ones. As a result, 1 in TS-VOB
A section corresponding to one broadcast program is recognized as an extended attribute section, a section marker for identifying this extended attribute section is created, and incorporated into PGC information. By specifying a section corresponding to one broadcast program in the TS-VOB as an extended attribute section, it is possible to suitably perform extended control such as cueing for this broadcast program or skipping this broadcast program.

The carousel section detection unit 25 detects, as an extended attribute section, a section in the digital broadcast signal in which an interactive broadcast program is transmitted. The detection of the extended attribute section by the carousel section detection unit 25 is realized by detecting the section transmitted by the data carousel method. The data carousel is a broadcasting system in which the same contents are repeated to realize interactive broadcasting. The same content that is repeatedly broadcast includes a BML document described in BML (Broadcast Markup Languege) and monomedia data referred to by this BML document. The data that is repeatedly transmitted by the data carousel is divided into multiple pieces, and the DDB (Dawnlo
It is stored in a block called ad Datablock), and DII (Downl
It is transmitted with unique control information called oadinfoIndicatin). This DII is transmitted prior to the DBB, and the data length of the DBB is described in this DII. A section is specified, a section marker that specifies this extended attribute section is created, and embedded in the PGC information. Data carousel method By designating a data block to be transmitted as an extended attribute section, it is possible to suitably perform extended control such as cueing for this data block or skipping this data block.

As described above, according to the present embodiment, the program arrangement change section detection unit 24 monitors whether there is a change in the program arrangement information, and a signal section having a specific program arrangement attribute is included in the digital broadcast signal. If present, the TS-VOB generates a section marker that specifies an extended attribute section corresponding to this signal section. As a result, the location of the program can be displayed in TS-VOB, which has a length of time such as half a day or a day. Therefore, the locations of the programs included in the AV file can be narrowed down. If the location of the program is clarified in this manner, the playback path including the section can be generated, so that the cue from the next time can be suitably performed.
Since it takes time to find the content for the user's own viewing, each user does not feel frustrated even when a plurality of users desire to view the recorded content recorded on the DVD.

The program arrangement change section detection unit 24 uses the PSI / SI
Although the location of the program was detected by monitoring the change in, the section where the playback-prohibited signal attribute is set because it is a pay broadcast and the recording restriction (only one
A section in which the signal attribute of (copy) is set may be detected as an extended attribute section and a section marker indicating this extended attribute section may be created.

In the digital broadcast signal and the analog broadcast signal, a signal section including an EPG indicating a specific genre, cast, and title is detected as an extended attribute section, and a section marker designating this is generated in the VOB information. You may. Then, during playback, extended control of displaying these genres, casts, and titles may be executed.

(Seventh Embodiment) In the present embodiment, when a section in which program arrangement information is changed or a section transmitted by the data carousel method is detected as an extended attribute section, how is it in these extended attribute sections? Whether to perform advanced extension control is disclosed. The improvements in this embodiment are made to the extended control execution unit 20 and the extended control arbitration unit 21. The extended control execution unit 20 and the extended control arbitration unit 21 will be described.

If the extended attribute section designated by the section marker is a section in which the program arrangement information has changed, the extension control execution unit 20 skips the reproduction point to the beginning of the section in which the program arrangement information has changed. The extended control is performed. Some of the program sequence information must be read by the playback device side in advance, and in order to ensure that the playback device side can read the program sequence information in the section where the program sequence information is changing, Extended control is performed to skip the playback point to the beginning of the section where the information has changed. If the extended attribute section designated by the section marker is data that is repeatedly transmitted by the data carousel method, the extended control execution unit 20 says that only one of a plurality of data transmitted by the data carousel method is reproduced. Achieve extended control. The above is the extended control performed by the extended control execution unit 20. Next, the extended control arbitration unit 21 will be described.

When the extended attribute section having the program arrangement information or the attribute of the data carousel method and the extended attribute section having the attribute of the unviewed attribute overlap, the extended control arbitration unit 21 overlaps them. Arbitration of the competition between the extended controls that may occur in. Hereinafter, how the extension control is performed by the arbitration by the extension control arbitration unit 21 will be described.

In FIG. 26A, since the section in which the program arrangement information has changed and the unviewed section overlap, the extension control unique to the unviewed section and the extension control unique to the section in which the program arrangement information has changed. The following shows an example in which there is a conflict. In this case, the start point my1 of the unviewed section exists inside the section where the program arrangement information has changed. Since the extended control unique to the unviewed section is to start the reproduction from the beginning of the unviewed section, the reproduction should originally be started from the beginning of the unviewed section. However, since the start point my1 of the unviewed section is inside the section where the program arrangement information has changed and overlaps with the section where the program arrangement information has changed, there is competition with "extended control unique to the section where the program arrangement information has changed". Occurs. If the priority of the "extended control peculiar to the section in which the program arrangement information has changed" is set higher than the priority of the "extended control peculiar to the unviewed section", the "extended control peculiar to the unviewed section" is set. Instead, the "extended control peculiar to the section where the program arrangement information has changed" is exceptionally executed. That is, FIG. 26 (a)
As indicated by the arrow ty1, the playback point is moved back to the beginning of the section where the program arrangement information has changed, and reproduction is performed from the beginning hc1 of the "section where the program arrangement information has changed".

In FIG. 26B, since the section in which the data is transmitted by the carousel method (the carousel section) and the unviewed section overlap, the expansion control unique to the unviewed section and the expansion unique to the carousel section. The following shows an example of conflict with control. The extended control unique to the unviewed section is to reproduce the entire unviewed section as it is, and in this state, all carousel sections included in the unviewed section are reproduced. On the other hand, the extended control peculiar to the carousel section is to "reproduce one of a plurality of data blocks", so that competition between the two occurs. If the priority of "extended control specific to carousel section" is higher than that of "extended control specific to unviewed section", in the overlapping part of the carousel section, instead of "extended control specific to unviewed section", an exception "Extensive control peculiar to carousel section" is executed. In other words, instead of playing the entire unviewed section,
One of the plurality of data blocks is reproduced as shown by arrow sr1 and the rest is skipped as shown by arrow sr2.

As described above, according to the present embodiment, when the unviewed section set in the reproduction route for each user overlaps with the carousel section and the section in which the program sequence information changes, the carousel section, the program Since the extended control based on the changing section of the array information is exceptionally performed, the processing based on the control information transmitted by digital broadcasting can be faithfully executed.

(Eighth Embodiment) In the second embodiment, a digital broadcast signal selected by demodulating a broadcast wave and selecting a channel, that is, a digital broadcast signal corresponding to a single program,
Converted to TS-VOB. In the present embodiment, a digital broadcast signal obtained by demodulating a broadcast wave that has not been selected, that is, a digital broadcast signal corresponding to a plurality of programs is
Regarding the improvement when converting to TS-VOB. This TS-VOB is called a multi-program TS-VOB, and the recording apparatus 100 according to this embodiment is configured to realize recording / reproduction of this multi-program TS-VOB. FIG. 27 is a diagram showing the internal configuration of the recording apparatus 100 according to this embodiment. In the figure, some of the components of the recording apparatus 100 are omitted, and instead, the paths of the multi-program TS-VOB are represented by dashed arrows zs1 and zs2. The multi-program TS-VOB read from the DVD 1 to the track buffer 5 as shown by the arrow zs1 is output to the digital tuner 8,
The signal is output from the digital tuner 8 to the recording controller 15 as indicated by an arrow zs2. In order to transfer the multi-program TS-VOB through such a route, the map creation unit 11, the reproduction control unit 17, and the extended attribute section detection unit 12 according to this embodiment.
Has been given a unique improvement.

The map creating section 11 creates an access map without analyzing the TS header and applicable fields of the TS packet. Specifically, at predetermined time intervals,
TS output from the digital tuner 8 to the extraction unit 9
The ATS of the packet is read, and entry information that associates the ATS with the time interval is created. An access map is formed by repeatedly creating this entry information.

The reproduction controller 17 reads out the multi-program TS-VOB recorded on the DVD and outputs it to the digital tuner 8 as indicated by the broken arrow zs1. When the digital tuner 8 tunes in and the digital broadcast signal corresponding to one program is output from the digital tuner 8, the digital broadcast signal corresponding to this single program is decoded by the decoder 16 as indicated by the dashed arrow zs2. Output to. By outputting the single program to the decoder 16, the broadcast program selected by the digital tuner 8 is displayed and output.

When the user performs a tuning operation on the digital tuner 8, the extended attribute section detection unit 12 outputs information indicating the channel selected by the user to the digital tuner 8.
To get from. When the display output of the multi-program TS-VOB is performed by the television and the user thereafter performs a reproduction stop operation, a section marker indicating the location of the extended attribute section, which is an unviewed section, is created as in the second embodiment. The channel number acquired from the user interface unit 2 is incorporated in the section marker. As described above, when writing / reading the multi-program TS-VOB, the TS header of the TS packet and the applicable field are not analyzed, so the start and end points of the extended attribute section
It cannot be expressed using PTS. Therefore, the extended attribute section detection unit 12 uses ATS instead of PTS to represent the start point and the end point of the extended attribute section. In this case, multiple TSs
Of the ATSs added to the packet, it is desirable to express the start and end points of the extended attribute section by using the one closest to the PTS. As such an ATS, there is an ATS added to a TS packet output to the decoder 16 when a reproduction operation is performed by the user. FIG. 28 shows
FIG. 7 is a diagram showing a section marker in which a channel number is incorporated by an extended attribute section detection unit 12.

By the above processing, the section marker including the channel number is created. If the process of outputting the channel number included in this section marker to the digital tuner 8 at the time of the next reproduction is performed, the user does not need to perform a tuning operation on the digital tuner 8 at the time of the next reproduction. (Ninth Embodiment) The present invention relates to deletion editing for an extended attribute section designated by a section marker in PGC information. Figure 2
9 is a diagram showing an internal configuration of the recording apparatus according to the present embodiment. As shown in FIG. 9, the recording apparatus according to the present embodiment is
Note that the deletion editing unit 26 is provided. The deletion editing unit 26 performs a process of deleting a part of the extended attribute section, cell, or VOB. The deletion by the deletion editing unit 26 is performed by a process of updating the section marker, cell information, and VOB information. In addition, the deletion editor
With this deletion processing, cell information, section markers, and
The process of updating VOB information is performed. As described in the first embodiment, the extended attribute section designated by the section marker in the PGC information is represented by “indirect reference to indirect reference”. Not only when the cell or TS-VOB referenced by the extended attribute section is edited, but the cell or TS-VOB remains in its original state and only part or all of the extended attribute section is edited. May be deleted. Further, since the extended attribute section expresses the range in which the extended control is effective, not as a “point” but as a “section” having a temporal width, the deletion attribute of the extended attribute section by the deletion editing unit 26 The following modes are shown in case 1 to case 10.

<Case1> In case1, an extended attribute section is included in one cell, and the end of this extended attribute section is deleted. In this case 1, the start point information and end point information of the section marker are updated so that the start point and end point of the extended attribute section are immediately before and after the end that is the deleted portion. FIGS. 30 (a) and 30 (b) are diagrams showing how the TS-VOB-cell-extended attribute section transits before and after partial deletion in case 1, for comparison. In this figure, “(a)” indicates before deletion, and “(b)” indicates after deletion. Further, in the figure, the symbol "<" symbolically indicates the start point of the extended attribute section, and the symbol ">" symbolically indicates the end point of the extended attribute section. When the end cy11 of the extended attribute section is to be deleted in FIG. 30 (a), the start point of the extended attribute section is deleted so as to be immediately after this deleted portion as shown by the arrow cy12 in FIG. 30 (b). Updated by the editing unit 26.

<Case2> In case2, the extended attribute section is included in one cell, and the middle part of this extended attribute section is deleted. In this case, the extended attribute section is divided. This division consists of the following two processes by the deletion editing unit 26. The first process is a process of shrinking the former extended attribute section to a part preceding the middle part. For this reason, the end point information in the section marker is updated by the deletion editing unit 26 so that the end point of the extended attribute section is immediately before the middle part. The second process is a process of newly creating a section marker so that the part subsequent to this middle part becomes one extended attribute section. The start point information of the newly generated section marker specifies the point immediately after the middle part as the start point, and the end point information of the newly generated section marker specifies the former end point.

FIGS. 30 (c) and 30 (d) are diagrams showing how the TS-VOB-cell-extended attribute section transits before and after partial deletion in case 2 for comparison. Figure 30
When the middle part of the extended attribute section # 1 is to be deleted in (c), the extended attribute section # 1 of FIG.
As shown in (d), extended attribute section # 1 and extended attribute section # 2
The deletion editing unit 26 divides the two extended attribute sections. The deletion editing unit 26 updates the end point of the preceding extended attribute section # 1 to be yz1 immediately before this deleted portion and the start point of the following extended attribute section # 2 to be yz2 immediately after this deleted portion. To be done.

<Case3> In case3, the extended attribute section exists so as to cross the boundary of two or more cells, and the end portion thereof is deleted. This case3 is basically the same as case1. However, in case 3, the start point / end point of the extended attribute section after partial deletion may belong to a cell different from the start point / end point of the extended attribute section. Since the start point and the end point may belong to different cells, in this case 3, the deletion editing unit 26 changes “cell having extended attribute section start point” and “cell having extended attribute section end point”. As described above, the deletion editing unit 26 updates the start cell ID and end cell ID of the section marker.

FIGS. 31 (a) and 31 (b) are diagrams showing how the TS-VOB-cell-extended attribute section transits before and after partial deletion in case 3 for comparison. In this figure, “(a)” indicates before deletion, and “(b)” indicates after deletion. When the end ty31 of the extended attribute section is to be deleted in FIG. 31 (a), the start point of the extended attribute section should be ty32 immediately after this end, as shown in FIG. 31 (b).
It is updated by the deletion editing unit 26.

<Case4> In case4, the extended attribute section exists so as to extend over two or more cells, and the middle part of this extended attribute section is deleted. The processing of case4 is basically the same as that of case2. However, in this case 4, the end point of the extended attribute section after partial deletion and the start point of the extended attribute section newly obtained by partial deletion may belong to different cells. That is, with respect to the section marker of the former extended attribute section, the deletion editing unit 26 changes the end cell ID so as to change the "cell having the extended attribute section end point" to the cell located immediately before the middle part.

Regarding the newly obtained section marker of the extended attribute section, the "cell in which the extended attribute section start point exists" is changed to a cell located immediately after the middle part.
Set the starting cell ID. Then, the deletion editing unit 26 sets the end cell ID for the newly obtained section marker so that the "cell in which the extended attribute section end point exists" is changed to the cell in which the extended attribute section end point is located. . 32A and 32B are diagrams showing how the TS-VOB-cell-extended attribute section transits before and after partial deletion in case 4, for comparison. In the case of deleting the middle part of the extended attribute section in FIG. 32 (a),

Of these, when a cell is to be deleted, the extended attribute section included in this cell is also deleted by the deletion editing unit 26 as shown in FIG.

On the contrary, when the extended attribute section includes the cell to be deleted (case 5-2), it is considered that the cell to be deleted is the middle part to be deleted, and the deletion editing unit 2
6 performs the processing of case 4. The former extended attribute section is shortened to a portion preceding the deleted cell, and the portion following the deleted cell is set as a new extended attribute section. At this time, there is no more than one cell in the middle, so the deletion editing unit 26 updates the end cell ID of the section marker so as to advance the "cell in which the extended attribute section end point exists". FIG. 34 (a),
(B) shows TS- before and after partial deletion in case 5-2.
It is a figure which compares and shows how VOB-cell-extended attribute area changes. In this figure, "(a)" is before deletion, "
34B shows each after deletion. When cell # 2 of cells # 1 to # 5 is to be deleted in FIG. 34A, the middle part of the extended attribute section corresponding to this cell is deleted. The extended attribute section # 1 in FIG.
It is divided into two extended attribute sections # 1 and # 2 in FIG. The end point of the preceding extended attribute section # 1 is immediately before this middle part indicated by the arrow ty51, and the following extended attribute section
The starting point of # 2 is updated by the deletion editing unit 26 so as to be immediately after this intermediate portion indicated by the arrow ty52.

When the start point and end point of the extended attribute section are included in the deleted cell (case 5-3), "cell where extended attribute section start point exists""cell where extended attribute section end point exists" The deletion editing unit 26 updates the start cell ID and the end cell ID of the section marker so that is immediately before or after the deleted cell. Then, the deletion editing unit 26 updates the end point information of the section marker so that the picture data located immediately before the deleted cell is designated as the end point of the extended attribute section, and the picture data located immediately after the deleted cell is updated with the extended attribute. Update the start point information of the section marker so that it is specified as the start point of the section. FIGS. 35 (a) and 35 (b) are diagrams showing how the TS-VOB-cell-extended attribute section transits before and after partial deletion in case 5-3 for comparison. In this figure, “(a)” indicates before deletion, and “(b)” indicates after deletion. Cell # 1 of cells # 1 to # 5 in FIG.
To delete the end of the extended attribute section that overlaps with this.
It is equivalent to deleting sn1. As shown in FIG. 35 (b), the start point of the extended attribute section is immediately after this end portion sn1, so that the start point of the preceding extended attribute section is immediately after this deleted portion as indicated by arrow sn2. Is updated by the deletion editing unit 26.

<Case6> Case6 is the case where the end of any cell forming the reproduction path is partially deleted. In this case, the deletion editing unit 26 updates the start point information and the end point information of the cell information so as to indicate immediately before and after the end. If the end to be deleted contains the extended attribute section (6-1),
All the extended attribute sections are deleted by the deletion editing unit 26. FIGS. 36 (a) and 36 (b) are diagrams showing how TS-VOB-cell-extended attribute sections transit before and after partial deletion in case 6-1 for comparison. In this figure, "(a)"
Indicates before deletion, and “(b)” indicates after deletion. Fig. 36
In (a), the tip portion sm1 of cell # 2 among cells # 1 to # 5
36B, the extended attribute section # 1 included in the tip portion is also deleted by the deletion editing unit 26 as shown in FIG.

On the contrary, when the extended attribute section includes the end portion (6-2), the deletion editing unit 26 performs the same update as the case 5 (5-2), and the portion preceding the end portion, The part following the end is set as a separate extended attribute section. FIG. 37
(A), (b) is a figure which compares and shows how a TS-VOB-cell-extended attribute section transits before and after partial deletion in case 6-2. In this figure, “(a)” indicates before deletion, and “(b)” indicates after deletion. Figure 37 (a)
When trying to delete the tip part of the cell # 2 of the cells # 1 to # 4, the middle part of the extended attribute section corresponding to this cell is deleted. The extended attribute section # 1 is shown in FIG.
It is divided into two extended attribute sections # 1 and # 2 in (b).
The end point of the preceding extended attribute section # 1 is immediately before this middle part as shown by arrow ty61, and the following extended attribute section
The starting point of # 2 is updated by the deletion editing unit 26 so as to be immediately after this intermediate portion as indicated by the arrow ty62.

It is a figure which shows how a TS-VOB-cell-extended attribute section changes before and after partial deletion in 6-3 for comparison. In this figure, “(a)” indicates before deletion, and “(b)” indicates after deletion. In FIG. 38A, deleting the tip of cell # 2 among cells # 1 to # 5 is equivalent to deleting the tip of the extended attribute section # 1 that overlaps with this. Since the start point of the extended attribute section # 1 in FIG. 38B is immediately after this end, the deletion editing unit 26 updates the start point of the preceding extended attribute section immediately after this deleted portion. To be done.

<Case7> Case7 is a case where the middle part of any cell constituting the reproduction path is deleted. In this case, the deleting / editing unit 26 updates the end point information of the cell information so that the cell occupies just before the middle part.
Immediately after this cell information, new cell information is added. The start point information of the newly added cell information specifies the start point of the new cell immediately after the deleted portion, and the end point information sets the end point of the old cell to the end point of the new cell. Is specified. FIGS. 39 (a) and 39 (b) are diagrams showing how they change before and after the deletion of the middle part of the cell. In this figure, "(a)" is before deletion, "(b)"
Indicates after deletion. Cell # 1 in FIG. 39 (a)
~ It is assumed that the middle part of cell # 2 of # 5 will be deleted. As shown in FIG. 39B, after the deletion of the middle part of the cell # 2, the cell # 2 is shortened to the length immediately before the middle part. It can be seen that a new cell # 2 'is obtained immediately after the deleted portion.

When the middle part to be deleted contains the extended attribute section (case 7-1), all the extended attribute section are deleted. FIGS. 40 (a) and 40 (b) are diagrams showing how the TS-VOB-cell-extended attribute section transits before and after partial deletion in case 7-1, for comparison.

After the deletion of the middle part of the cell # 2, the extended attribute section included in the middle part of the cell # 2 is deleted by the deletion editing unit 26 as shown in FIG.

On the contrary, when the extended attribute section includes the middle part to be deleted (case 7-2), the deletion editing unit 26 sets cas
e5-2 The same update is performed, and the part preceding the end and the part following the end are set as separate extended attribute sections.
41A and 41B are diagrams showing how the TS-VOB-cell-extended attribute section transits before and after partial deletion in case 7-2, for comparison. In this figure
"(A)" indicates before deletion and "(b)" indicates after deletion. The middle part is also deleted by the deletion editing unit 26. FIG.
The extended attribute section # 1 in (a) is divided into two extended attribute sections # 1 and # 2 as shown in FIG. 41 (b). The end point of the preceding extended attribute section is immediately before this middle part,
The start point of the subsequent extended attribute section is updated by the deletion editing unit 26 so as to be immediately after this intermediate part.

When the start point and end point of the extended attribute section are included in the middle part to be deleted (case 7-3), case
After performing the processing of 5-3, the deletion editing unit 26 sets the section "cell having the start point of the extended attribute section" and "cell having the end point of the extended attribute section" to be the newly obtained cell. The start and end cell IDs of the marker are updated, and the deletion editing unit 26 sets the section marker so that the start and end points of the section marker are the first picture data and the last picture data in the newly obtained cell. Starting point information
Update end point information.

FIGS. 42 (a) and 42 (b) are diagrams showing how the TS-VOB-cell-extended attribute section transits before and after partial deletion in case 7-3 for comparison. In this figure, “(a)” indicates before deletion, and “(b)” indicates after deletion. As shown in FIG. 42 (a), cells among cells # 1 to # 5
When attempting to delete the middle part of # 2, the end part of the extended attribute section # 1 included in this part will be deleted by the deletion editing part 26. The start point of the extended attribute section is shown in FIG.
As shown in (b), since it is immediately after this end, the start point of extended attribute section # 1 should be immediately after this deleted portion.
It is updated by the deletion editing unit 26.

<Case8> Case8 is a case of completely deleting any TS-VOB recorded in the AV file. The cell that constitutes the playback path is included in any TS-VOB. In other words, there can never be a cell that crosses the TS-VOB boundary. This makes a distinction that the extended attribute section can cross the boundary of a plurality of cells. Because the starting point and the ending point of the cell are defined by indirect reference via the access map, if the starting point and the ending point of the cell cross the boundary of TS-VOB, multiple access maps are required. This is because the processing load increases. Therefore, the case where all the TS-VOBs are deleted can be equated with the case where all the cells included in the TS-VOBs are deleted. When any TS-VOB is completely deleted, all cells included in this TS-VOB are all deleted by the deletion editing unit 26. Therefore, the processing of case5 should be performed. 43 (a) and 43 (b) are diagrams showing the transition of the TS-VOB-cell-extended attribute section before and after the case 8 is deleted. In this figure, “(a)” indicates before deletion, and “(b)” indicates after deletion. As shown in FIG. 43 (a), VOB # 1 to VOB
When VOB # 1 of # 4 is deleted, it can be seen that the cells and extended attribute sections included in VOB # 1 are all deleted as shown in FIG. 43 (b).

<Case9> In case9, the end of any TS-VOB recorded in the AV file is partially deleted. When deleting a part of an end, it is necessary to delete the entry information corresponding to this end in the access map. With respect to the extended attribute section and the reproduction path, the processing changes depending on whether or not the cell is included in the deleted portion. If the deleted part contains the cell
(9-1), it may be considered in the same manner as the case of deleting all cells, and the process of case 5 may be performed. FIGS. 44 (a) and 44 (b) are diagrams showing how the TS-VOB-cell-extended attribute section transits before and after partial deletion in case 9-1 for comparison. In this figure, “(a)” indicates before deletion, and “(b)” indicates after deletion. Of VOB # 1 to VOB # 3, deleting the end of VOB # 1 as shown in FIG. 44 (a) means that the cell # 1 included in this end and a part or all of this cell are included. It is equivalent to deleting the included extended attribute section # 1. In FIG. 44 (b), the cell # 1 included in the tip portion of the TS-VOB and the extended attribute section # 1 in which the cell includes the tip portion are deleted.
It can be seen that it is deleted by 6. When the end to be deleted is the end of the cell (case 9-2), it can be considered in the same way as case 6. FIGS. 45 (a) and 45 (b) are diagrams showing how TS-VOB-cell-extended attribute sections transit before and after partial deletion in case 9-2, for comparison. In this figure, “(a)” indicates before deletion, and “(b)” indicates after deletion. Deleting the end portion of VOB # 1 in FIG. 45 (a) is equivalent to deleting the leading end portion of cell # 1 included in this end portion and the extended attribute section partially included in this cell. become. In FIG. 45 (b), the cell # 1 including the tip portion at the end of the TS-VOB and the extended attribute section # 1 including the tip portion in this cell are deleted by the deletion editing unit 26. Recognize.

<Case10> Case10 is a case where the middle part of the TS-VOB recorded in the AV file is deleted. In this case, TS-VOB is divided. The division here means
It consists of two processes. The first process is to shrink the former TS-VOB to the preceding part that precedes the middle part, and the second process is the part that follows this middle part.
It is to add to the AV file as a new TS-VOB.
VOB information is divided according to the division of TS-VOB. In this division, the access map is divided along with the division of TS-VOB. 2 with two access maps obtained by division
It generates one VOB information and associates it with each of the two TS-VOBs.

If the middle part of the TS-VOB is deleted, the TS-VOB is divided by this deletion. At this time, VOB
Information must also be divided. This division of VOB information is described in detail in US Pat. No. 6,148,140, so refer to this publication. This document describes how to seamlessly reproduce two TS-VOBs obtained by division. VO in this embodiment
It can be considered that the division of B is based on the technique described in this publication.

Furthermore, when deleting the leading end portion or the middle portion of the TS-VOB, it is necessary to update the access map accordingly. The details of this update of the access map are described in International Publication WO99 / 14754.
See this publication. In this publication, the access map is expressed as a "time map", but it is substantially synonymous with the access map.

FIGS. 46 (a) and 46 (b) are diagrams showing the transition of the TS-VOB-cell when the middle part of the TS-VOB is deleted. In this figure, “(a)” indicates before deletion, and “(b)” indicates after deletion. After the deletion of the middle part shown in FIG. 46 (a), the former VOB # 1 is shortened by the deletion editing unit 26 to the length immediately before the middle part together with the cell. Immediately after the deleted portion, it can be seen that a new TS-VOB # 1 'is obtained as shown in FIG. 46 (b).

If the middle part to be deleted contains a cell (case 10-1), the process of case 5 may be performed.
47 (a) and 47 (b) are diagrams showing how the TS-VOB-cell-extended attribute section transits before and after partial deletion in case 10-1 for comparison. In this figure
(A) "Before deletion, and" (b) "is after deletion. Deleting the middle part of VOB # 1 in Fig. 47 (a) means that cell # 1 included in this middle part and this This is equivalent to deleting the end of the extended attribute section in which a part or all of the cell is included.In Fig. 47 (b), cell # 2 included in the middle part of VOB # 1 and this cell # 2 are included. The extended editing section 26 including the leading end portion is deleted by the deletion editing unit 26.

When the middle part includes the end of the cell
(case10-2), case6 should be processed. FIG. 48 (a),
(B) shows TS before and after partial deletion in case 10-2.
It is a figure which contrasts and shows how VOB-cell-extended attribute section changes. In this figure, "(a)" is before deletion, "
(B) "indicates after deletion. Deleting the middle part of TS-VOB in Fig. 48 (a) means that the tip part of cell # 1 included in this end part or part of this cell This is equivalent to deleting the end of the extended attribute section that includes all of the cells in Fig. 48 (b), in which cell # 1 includes the tip part at the end of TS-VOB and this cell includes the tip part. It can be seen that the extended attribute section # 1 to be deleted is deleted by the deletion editing unit 26. When the middle part to be deleted contains the middle part of the cell (case 10-3), if the process of case 7 is performed, 49 (a) and 49 (b) are diagrams showing how the TS-VOB-cell-extended attribute section transits before and after partial deletion in case 10-3, in comparison with each other. "(A)" shows before deletion and "(b)" shows after deletion.The middle part of VOB # 1 is deleted in Fig. 49 (a). This is equivalent to deleting the middle part of the cell # 1 and the extended attribute section # 1 part or all of which is included in the middle part of the cell # 1. The cell # 1 including the middle part and the extended attribute section # 1 including the middle part are deleted and converted into two cells # 1 and # 1 ', and two extended attribute sections # 1 and # 2 respectively. You can see that it is done.

As described above, according to the present embodiment, not only the middle part or the end part of the extended attribute section is partially deleted, but also the extended attribute section is partially deleted due to the total deletion or partial deletion of the cell or TS-VOB. Can be deleted. Therefore, it is possible to freely change the form of the extended attribute section according to various edits that may be made in the hierarchical structure of TS-VOB-access map-playback route shown in the first embodiment.

In this embodiment, only the section marker in the PGC information has been described, but it goes without saying that the section marker in the VOB information is also deleted in the same manner. In other words, it is possible to partially delete the extended attribute section along with all or partial deletion of TS-VOB. (Tenth Embodiment) This embodiment is an improvement in the case where the recording device 100 performs moving edit of moving a cell constituting a reproduction path, and editing the extended attribute section in accordance with the moving edit. Regarding It should be noted that FIG. 50 is a diagram showing the internal configuration of the recording apparatus according to the present embodiment, and as shown in the figure, the recording apparatus according to the present embodiment includes a moving / editing unit 27. The moving / editing unit 27 performs a process of moving a cell forming a reproduction path. The movement by the movement editing unit 27 is performed by a process of updating the section marker and cell information.

FIGS. 51 (a) and 51 (b) schematically show a moving edit in which the cell # 1 of the four cells # 1 to # 4 constituting the reproduction path is moved immediately after the cell # 3. FIG.
As shown in FIG. 51 (a), the playback paths are cell # 1 and cell # 1.
2, cell # 3, cell # 4 was the order, but by moving cell # 1 as shown by arrow mv0, the order of this playback path is cell # 2, cell # 3, cell # 1, It becomes cell # 4. The reproduction path is an array of a plurality of cells, and the location of the extended attribute section is designated by indirect reference via any of the plurality of cells.
Since the indirect reference by the section marker has a format that depends on the cell array, it seems that the extended attribute section also changes if the cell array that is indirectly referenced changes. However, the section marker specifies only the start and end points of the extended attribute section. Therefore, even if the cell array forming the reproduction path changes, it is often necessary to change the cell information array.

That is, for any cell, the starting point,
Since it is defined in the format of specifying the end point, even if any cell that contains the extended attribute section moves outside the extended attribute section, cells outside the extended attribute section move into the extended attribute section. Even if a cell in the extended attribute section moves to somewhere in the same extended attribute section, there is no effect. However, be careful when moving a cell that includes the end point and the start point. That is the case where the end point comes before the start point. If the order of the end point and the start point is reversed, the validity of the extended attribute section fails. So when moving cells,
It is determined whether or not the order of the start point and the end point is interchanged by the movement, and if they are interchanged, the movement editing unit 27 updates the section marker to prevent the above-mentioned failure of the correctness.

The section marker updating process for preventing the validity failure of the extended attribute section will be described. When moving and editing a cell is about to be performed, it is determined whether the cell to be moved is a cell including a start point or a cell including an end point. If the cell to be moved is a cell including the start point, it is determined whether or not the cell including the start point comes after the cell including the end point. If it is later, the move editing unit 27 updates the start cell ID and the start point information in the section marker so that the start point of the extended attribute section is immediately after the cell to be moved. By doing this, although the leading end of the extended attribute section is shortened, it is possible to avoid the failure of the correctness of the extended attribute section due to the start point coming before the end point.

FIGS. 51 (c) and 51 (d) are diagrams showing a moving process of moving a cell including the extended attribute section start point. Of cells # 1 to # 4 in the figure, cell # 1 has a start point of the extended attribute section and cell # 3 has an end point of the extended attribute section. Cell # 1 where this starting point exists
Is to be moved between cell # 2 and cell # 3 as indicated by arrow my1. In this case, since cell # 1 is located before cell # 3 where the end point of the extended attribute section exists, the moving editing unit 27 does not update the section marker.

FIGS. 52 (a) and 52 (b) are diagrams showing how to update the section marker when moving the cell including the extended attribute section start point. Cell # 1 where this starting point exists is changed to cell # 3 as indicated by arrow my2.
-Assume a case where an attempt is made to move between cells # 4. In this case, cell # 1 is the cell where the end point of the extended attribute section exists.
Since it is located after # 3, the legitimacy of the extended attribute section will be broken if it is left as it is. Therefore, the movement editing unit 27 updates the section marker so that the start point of the extended attribute section is the head of cell # 2, which is immediately after cell # 1.

If the cell to be moved is a cell including the end point, it is determined whether or not the cell including the end point comes before the cell including the start point. If it is before, the move editing unit 27 updates the entry information and the end cell ID so that the end point of the extended attribute section is immediately before the cell to be moved. By doing so, although the entry information of the extended attribute section is shortened, it is possible to prevent the validity failure of the extended attribute section due to the end point coming before the start point.

FIGS. 53 (a) and 53 (b) are diagrams showing a moving process of moving a cell including the extended attribute section end point. Of cells # 1 to # 4 in FIG. 53A, cell # 1 has a start point of the extended attribute section and cell # 3 has an end point of the extended attribute section. The cell # 3 in which this end point exists is the cell # 3 as shown by the arrow my5 in FIG.
Assume a case in which an attempt is made to move between 1-cell # 2.
In this case, the cell # 3 is located after the cell # 1 in which the start point of the extended attribute section exists, and therefore the movement editing unit 27 does not update the section marker.

The cell # 3 in which this end point exists is moved to the arrow my5.
Suppose that the user wants to move the cell before cell # 1 as shown in. FIGS. 54 (a) and 54 (b) are diagrams showing a section marker updating process when a cell including the extended attribute section end point is moved. In this case, as shown in FIG. 54 (a), the cell # 3 is positioned before the cell # 1 where the end point of the extended attribute section exists, so that the validity of the extended attribute section fails as it is. I will end up. Therefore, FIG.
As shown in (b), the movement editing unit 27 updates the section marker so that the end point of the extended attribute section is at the end of cell # 3, which is immediately after cell # 1.

As described above, according to the present embodiment, even when the cell is freely moved by the user, it is possible to prevent the legitimate failure of the extended attribute section due to the cell movement. still,
In the present embodiment, only the section marker in the PGC information has been described, but it goes without saying that the same processing is performed for the section marker in the VOB information.

Although the cell movement has been described in the present embodiment, it goes without saying that the extended attribute section itself may be moved without moving the cell. (Eleventh Embodiment) This embodiment is an embodiment in which individual designation of extended attribute sections for one playback path and collective designation of extended attribute sections for a plurality of playback paths are realized through user operations. Since the individual designation and the collective designation are realized through the user operation, the user interface unit 2 in the recording apparatus in this embodiment performs the following processing. First, the user interface unit 2 receives from the user whether to individually specify the extended attribute section or to collectively specify the extended attribute section. When the individual designation is accepted, the login operation is performed for the user who intends to designate the extended attribute section, and the user who intends to perform the manipulation is specified. When the user identification is completed, the reproduction route for the user is displayed, and the process proceeds to the individual designation process of the extended attribute section for this reproduction route. In this case,
Alternatively, as shown in FIG. 10, a screen in which the reproduction path for each user is schematically displayed is displayed. For the playback path on this screen, the user accepts the setting operation of where to set the start point of the extended attribute section on the playback path and where to set the end point of the extended attribute section to the playback path. It At this time, the user interface unit 2 displays a cursor on the reproduction path, and moves the cursor left and right according to the user's operation on the remote controller. Here, it is desirable to display what kind of picture data exists at the cursor position by a thumbnail or the like. This is because the setting of the extended attribute section becomes more accurate. Then, when the user performs an operation of fixing the position of the cursor, the position is set as the start point or the end point. Once the start and end points are set,
A section marker having time information indicating the start point and the end point is incorporated in the PGC information in the resident memory 4.

When performing batch designation processing of extended attribute sections,
As shown in FIG. 11, a screen in which the playback paths for a plurality of users are schematically displayed is displayed. For the multiple playback paths on this screen, the user can set the start point of the extended attribute section on the playback path and the end point of the extended attribute section on the playback path. Attach. At this time, the user interface unit 2 displays a cursor on the reproduction path and moves the cursor left and right on the plurality of reproduction paths according to the user's operation on the remote controller. Then, when the user performs an operation of fixing the position of the cursor, the position is set as the start point or the end point. When the start point and the end point are set, the section marker having the time information indicating the start point and the end point is set in the resident memory 4
Embedded in the VOB information in.

By the user interface unit 2 performing the above-described processing, the user can freely set the extended attribute section. In the case of performing the editing as described in the ninth and tenth embodiments, the user interface unit 2 may receive the designation of the portion to be deleted. In this case, as shown in FIGS. 30 to 49, screens in which the extended attribute sections, cells, and VOBs are schematically displayed are displayed, and the extended attribute sections, cells, and VOBs on these screens are deleted based on user operations. It specifies a part of the extended attribute section, a part of the cell, and a part of the VOB.

Although the description has been given based on the above embodiment,
It is only presented as an example of a system that can be expected to have the best effect under the current circumstances. The present invention can be modified and implemented without departing from the gist thereof. The following (A), (B), (C), ... (A) Recording device 1 described in the first to eighth embodiments
Many of the features of 00 are shown in FIGS. 14, 15, 19, and 20.
As shown in the flowchart of FIG. Therefore, this characteristic program may be implemented independently of these devices. If the program is recorded on a computer-readable recording medium, transfer this recording medium,
You may implement only a program in the mode of lending. Further, when the program is distributed on the network, the program may be implemented in a form of transmitting the program on the network. In addition, even if there is a characteristic part other than these, as for the characteristic that is essentially implemented as an improvement of the program, the program as the characteristic part may be recorded in a recording medium or may be transmitted to a network. Good.

(B) In the first to tenth embodiments, the DVD-RA
Although the description has proceeded using a DVD that can record moving image data as an example of a recording medium that conforms to the DVD-VIDEO RECORDING standard, such as M, the physical structure of a recording medium that can record moving image data is Any recording medium may be used. For example,
It may be a phase change type optical disc such as a DVD-RW, a PD, a DVD + RW, a CD-RW other than the DVD-RAM. Also, write-once type optical disks (i) such as CD-R, DVD-R, MO (Magneto-optical disk), MD
-Optical magnetic storage type optical disk (ii) such as DAT (Mini disc-Data), iD format, removable hard disk drive (i.e., ORB, Jaz, SparQ, SyJet, EZFley, Microdrive)
ii), flexible disks, magnetic recording disks such as SuperDisk, Zip, Clik! (iv), SD memory cards, CompactFlash (registered trademark) cards, smart media, memory sticks, multimedia cards, flashes such as PCM-CIA cards It may be a memory card (v).

(C) The recording device 100 may be implemented as a home-use stationary DVD recorder such as Panasonic's DMR-E30, or may be implemented as a camcorder. In addition, the recording device 100 is "MotionDV STUDIO", "DVD MovieAl
It may be a personal computer in which a digital video editing program such as "bum" is installed and is connected to the drive device 3 via an interface conforming to SCSI, IDE or IEEE1394.

(D) In this embodiment, the video stream and the audio stream are multiplexed in the TS-VOB, but the sub-picture stream in which the subtitle characters are run-length compressed and other control information are multiplexed. Good. (E) In this embodiment, the display period of the picture data is described by the video frame, but like the film material,
When using 3: 2 pulldown, which is used when compressing 24 frames / second video, 1 frame = 1 picture, not
The relationship of 1.5 frames = 1 picture may be used.

(F) In all of the embodiments, the optical disc is used to record moving image data in a format conforming to the DVD-VIDEO RECORDING standard, but it may be recorded in conformity with other standards.

[0152]

As described above, in the recording apparatus according to the present invention, when the contents of the extended control performed during reproduction are effective only within the reproduction path indicated by one reproduction path information, the reproduction is performed. If a section for which extended control is to be performed is individually specified for a route (1) and it is effective in multiple playback paths, the sections for which extended control is to be performed are collectively set for multiple playback paths indicated by the multiple playback path information. (2) Designating means for designating, marker information of the first type indicating where the section individually designated by the designating means exists in the reproduction path, and where the section designated collectively in the digital stream is Since at least one of the marker information of the second type indicating whether the reproduction information exists in the recording medium is included in the recording medium, one reproduction path information is assigned to a specific user. Lever, the individual specification for one reproduction path, it is possible to specify a section to be subjected to extended control for each user. Thereby, the unviewed section can be set for each user. In addition, by specifying individual sections for such a reproduction path, it is possible to execute extended control that respects the attention and convenience of each user.

By specifying sections for multiple playback paths at once, skipping adult scenes and violent scenes, commercials
Extended control such as skipping a section can be uniformly performed during reproduction by a plurality of users. As a result, the recording apparatus is released from the obligation to store the section in which the extended control should be performed for each user, and the processing can be simplified. Extended control that should be performed individually for each user,
By selectively using the extended control that should be uniformly performed for a plurality of users, the manufacturer of the recording apparatus can manufacture the recording apparatus with higher user needs and put it on the market.

Here, the reading means for reading out the first type marker information and the second type marker information from the recording medium from the recording medium, and the reproducing path indicated by the reproducing path information, by the first type marker information. In the designated section, extended control peculiar to the playback path is performed, and in the section that overlaps the section designated by the second type marker information, the extended control is performed. Instead of or in addition to the extended control,
A playback device may be configured to include control means for performing extended control specific to the digital stream. It is assumed that there are n types of digital streams and there are m playback paths for each user. In this case, if the control means performs stream-specific extension control for each of the n types of streams and performs playback-path-specific extension control for each of the m pieces of playback path information, the number of variations of the extension control by the playback device is reduced. , N × m ways. In other words, "n + m"
By performing the extended control of, it is possible to realize n × m variations.
