Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a karaoke apparatus, and more particularly to a background video system in a karaoke apparatus.
[0002]
[Prior art]
In a karaoke apparatus, a video for a long time is generally stored in a video database in order to display as a mood video when playing accompaniment music of karaoke music. The video for a long period of time stored in this video database is selected and reproduced as an appropriate segment according to the performance music as a background video.
[0003]
As a selective playback method, a video segment identifier is assigned to each video segment for a long time and managed, and a segment video to be played back for each music is described by a permutation of the video segment identifier. A method using script data has been proposed. In this case, the karaoke device that refers to the script data of the performance music recognizes the video segment identifier according to the script from the corresponding disc medium, and connects and reproduces the corresponding segment video.
[0004]
[Problems to be solved by the invention]
However, if a background image is to be reproduced for a new song or the like for which the above script data is not set, it has been difficult to process this quickly and smoothly. In this case, for example, an emergency video for each music genre is prepared in advance, and an emergency video of the same genre as a new song scheduled to be played is selected and played as a background video. However, when this technique is executed, for example, the genre such as “Rock” or “Enka” is the same, but the emergency video originally created mainly considering universality that is easy to match across songs and the new songs The gap with a brand new image is apt to grow. If a karaoke user has a new song that has been challenged, he / she feels that the background image has a sense of incompatibility with the song, or that he / she has seen it several times when playing other songs. This is one of the karaoke interests.
[0005]
On the other hand, in order to fully support new songs that are released one after another, it is costly to create excellent background video that conforms to the image of the song and story development without time lag and to compose the script data describing the permutations and combinations. It can be said that it is very difficult. In other words, immediately after the release of a new song, there was a situation where it was absolutely necessary to rely on the emergency video.
[0006]
Therefore, the present invention provides a background video system that can easily and quickly select script data that matches a song to be played karaoke and reproduce an appropriate background video when original script data is not set for the song to be played karaoke. The purpose is to provide.
[0007]
[Means for Solving the Problems]
The present invention is a background video system in a karaoke apparatus for achieving the above object, wherein the first invention reproduces a segmented video specified by a video segment identifier from videos stored in a video database. Then, in the karaoke device that outputs the background video of the lyrics subtitles at the time of karaoke performance, a plurality of segmented videos that are produced for each song according to the taste of each song and that should be played during the karaoke performance period for one song are sequentially Means for managing a script database in which script data consisting of a permutation of video segment identifiers for designation is associated with each song; and when performing a karaoke performance of a song, the script data for that song is registered in the database If there is script data registered, there is original script search means for using it for background video playback processing. When script data for a song is not registered in the database when performing a karaoke performance, the script data associated with another song having a predetermined classification attribute in common with the song is retrieved from the database. And an alternative script selection means for selecting one and using it for background video reproduction processing.
[0008]
According to a second aspect of the present invention, in the first aspect, in the case where a moving image is reproduced while a large number of media are selectively set at a reproduction position and is output as a background image of lyrics subtitles during karaoke performance, the alternative script selecting means , For the set of songs of other artists who share the same artist attributes as the original song artist of the song to be played karaoke, the first video segment identifier in the script data associated with these other songs is checked and played back It is characterized in that script data corresponding to the media set at the position is selected.
[0009]
According to a third aspect of the present invention, in the second aspect, in the case where a moving image is reproduced while a large number of media are selectively set at a reproduction position and is output as a background image of lyrics subtitles during karaoke performance, the alternative script selecting means , A set of other songs that share the same music genre with a song that plays karaoke among the set of songs of other artists who share the same artist attributes as the original song artist of the song that plays karaoke. The head video segment identifier in the script data that has been recorded is checked, and the script data corresponding to the media that is currently set at the playback position is selected.
[0010]
In a fourth aspect of the present invention, in the second or third aspect, in the case where a moving image is reproduced while a large number of media are selectively set at a reproduction position and is output as a background image of lyrics subtitles during karaoke performance, the alternative In the script selection means, the script data of the first video segment identifier in the script data associated with the other music piece that corresponds to the media that is currently set at the playback position is updated. One is selected according to the high order.
[0011]
In a fifth aspect of the present invention, in any one of the second to fourth aspects of the present invention, when a moving image is reproduced while a large number of media are selectively set at a reproduction position and is output as a background image of lyrics subtitles during karaoke performance In the alternative script selection means, the script data of the first video segment identifier in the script data associated with the other music, which corresponds to the media currently set at the playback position, is The process of selecting one according to the most recent order is repeated until a video segment identifier corresponding to the media currently set at the playback position is selected.
[0012]
DETAILED DESCRIPTION OF THE INVENTION
=== Basic configuration of karaoke equipment ===
FIG. 1 shows a configuration of a karaoke apparatus 1 according to the embodiment. The central control unit 11 is a microcomputer including a CPU, a RAM, and a ROM inside, and performs data communication with peripheral components via the data bus 100 and the control bus 110 to control / supervise the karaoke apparatus 1. . In addition to the karaoke data for a large number of songs, the hard disk device 12 also stores various data that are associated with each other so as to be searchable by the ID (music number) of the karaoke music. Karaoke data is accompaniment music generation data described in MIDI format, and lyrics that describe the lyrics characters to be drawn in synchronization with the performance of the accompaniment music and the attributes of the characters (display position, display color, display / erase timing) This is a set of rendering data.
[0013]
When the central control unit 11 receives the ID input of the requested music from the remote control transmitter 17 or the operation panel 18 via the operation control unit 19, the central control unit 11 stores the input order and the ID in association with each other in the RAM, and reserves the performance of the music. Register. Then, the karaoke data of the corresponding music is extracted according to the reservation order. Then, the MIDI data is transferred to the synthesizer 13. The synthesizer 13 controls the internal sound source according to the MIDI data, and generates karaoke accompaniment music. Karaoke accompaniment music is mixed with the singing voice signal from the microphone 15 by the mixing amplifier 14 and output to the speaker 16 as voice. On the other hand, a bitmap image corresponding to the lyric image is developed in the video RAM 20 based on the lyric rendering data. Further, the video database unit 30 is controlled to output an appropriate background video signal. The video control unit 21 superimposes the background video as the background of the lyrics image and outputs the video to the display 22.
[0014]
=== Configuration of Video Database ===
FIG. 2 shows a configuration diagram of the video database unit 30. The video database control unit 31 performs data communication with the central control unit 11 of the karaoke apparatus body 1 via the buses (100, 110), and controls each component of the video database unit 30. The disk storage unit 32 is loaded / accommodated with a large number (for example, 100 in this embodiment) of DVDs (hereinafter, disks) (Di: i is a number from 1 to 100). On each disc Di, a video for a long time (eg, 133 minutes as the playback time) prepared for display on the display as a background video during the performance of karaoke accompaniment music is encoded and compressed according to the MPEG2 standard. A video segment identifier is recorded as a segmented video segmented in a short time. The two disc drives 33 and 34 drive the disc Di supplied from the disc storage unit 32 by the disc loading mechanism 35, and read out the segmented video recorded on the disc Di using the video segment identifier as a key. The input switching unit 36 performs input switching of the segmented video output from the disk drives 33 and 34 and outputs the segmented video from the disc drive (33, 34) of an appropriate system to the MPEG2 decoding unit 37. The MPEG2 decoding unit 37 decompresses and decodes the input segmented video in real time to reproduce the video signal.
[0015]
Each of the multiple disks Di is assigned a disk number i (i is an integer of 1 to 100), and is loaded in a predetermined position of the disk storage unit 32 according to the number. Of course, identification data of its own number is also recorded on each disk Di. Further, the divided video at a desired data recording position on one disk Di can be accessed by the sector address assigned to each data sector. A desired sector address can be accessed in units of time of 1 second or less by specifying a time code (minute / second / frame) corresponding to the elapsed time when the video recorded on the disk Di is reproduced from the beginning. .
[0016]
Further, each disk Di has a VTS corresponding to “track number search” in a CD, and a specific sector address can be accessed by designating a predetermined VTS number. When the video database control unit 31 receives the disk number i and the sector address or VTS number from the central control unit 11, the video database control unit 31 controls the disk loading mechanism 35 and corresponds to the disk drive (33, 34) of an appropriate system. The disc Di is set, and the disc Di is driven to read out and join the desired segmented video to reproduce the background video. The set information of the disk number i and the sector address or VTS number described above is a “video segment identifier” that is information for identifying the segment video.
[0017]
=== Script Data and Video Database Operation ===
The background image displayed when a certain karaoke piece is played is obtained by connecting and editing short-time image materials (divided images) distributed and recorded on a large number of discs Di. In the video database unit 30, the two systems of disk drives 33 and 34 alternately take charge of playback processing and playback preparation, so that the divided videos are smoothly connected. Script data is the basis for connecting and editing short segmented videos in this way.
[0018]
This script data designates segmented video to be used during the performance of one piece of music by using a permutation of video segment identifiers. For example, the script data is described by a video segment identifier in which a disc number and a time code are set as described above. ing. The script data is associated with each karaoke song by its song number, and is stored in the hard disk device 12 with a script attribute representing its contents. In the script attribute, in addition to the corresponding music number, for example, a music genre such as “matches enka” or “matches female rock singer” or an artist-specific suitability, or more specifically “winter It can also be assumed that it matches the enka that sings the love of life by the image of the Sea of Japan. Of course, when the script data is not associated with a specific music piece, the music numbers are not linked. In other words, the music number of the music for which no script data has been produced is not associated with any script data.
[0019]
Note that each segmented video in the present embodiment is recorded with at least one of the meanings of starting and falling for each video. For example, for a song about the theme of “love”, a group of material images 1 that envisioned “starting” that makes you feel the beginning of a love story, such as a scene where men and women meet, depicting how love develops. Multiple material video group 2 that assumes “acceptance” such as a scene, one turn, multiple material video group 3 that assumes “turn” such as a scene in which love enters the transition period, and follows various trajectories In addition, a plurality of material video groups 4 that are supposed to be “concluded” such as a scene that finally has a happy ending are collected in a video database using a CD-ROM or the like as a recording medium.
[0020]
Of course, the above-mentioned “love” may be defined as an easy-to-fit video genre in accordance with the meaning of the settlement. Specific examples of this video genre include, for example, Japanese emotional images, city night view images, sad snowy ocean images, intense wave ocean images, Japanese mountain landscapes, Japanese urban night views. It is possible to express a scene such as a foreign city, a foreign mountain, a south island, or a story development such as a happy ending for men and women, a happy ending for families, a tragedy for men and women. If such a specific video genre is set, the selection of segmented video that matches the attributes of the music becomes more reliable, leading to the production and selection of excellent script data.
[0021]
The material video groups 1 and 4 are produced in a fixed length (eg 60 seconds), and the material video groups 2 and 3 are produced in about 90 seconds. Regarding the latter half of the material video groups 2 and 3, there is no sense of incongruity even if the material video group 3 or 4 is switched to the next material video group during playback. In order to cope with the performance, it is produced with a video content with a light storyline that portrays landscapes and scenes so that there is no sense of incongruity even during repeat playback.
[0022]
In addition, in the script data of each song, the first 60 seconds of the music performance is the playback section of the segmented video (referred to as the first video) corresponding to “start”, and the last 60 seconds is the segmented video (the fourth video and the fourth video). On the other hand, the music performance time of the intermediate part excluding the head part and the tail part is appropriately divided and divided videos corresponding to “approval” and “turn” (second video and third video) The playback section is assigned. By taking such a common structure for the script data across songs, even if the script data edited for other songs is borrowed, the difference in music performance time can be absorbed and smooth background video can be reproduced. It becomes.
[0023]
In this embodiment, three script data from Candidate 1 to Candidate 3 are produced for each piece of music and are associated with each piece of music. In the singer-specific music video index file 300 in FIG. 3B, the script data 301 of the candidates 1 to 3 set for each song is added to the singer incident numbers “01” to “05” corresponding to the artist number “5627”. It is a compilation of each song. As can be seen from the structure of the index file 300, each piece of music has three candidate script data 301, and each script data 301 is composed of a video segment identifier 302 that identifies the first to fourth videos corresponding to "starting and rolling". It is done. The video segment identifier 302 in the figure is only a simple number such as “104” or “103”. For example, a correspondence table (not shown) of these numbers and disk numbers and sector addresses or VTS numbers. Assume that selective playback of segmented video is executed using.
[0024]
When starting the performance process of a certain karaoke piece, the central control unit 11 takes out the corresponding script data together with the karaoke data from the hard disk device 12 and transfers it to the video database control unit 31. First, the video database control unit 31 controls the disc loading mechanism 35, for example, a disc Dj (j is 1 to 100) in which the disc drive 33 contains a segment video to be used as the beginning of the music, that is, the first video. Number). In addition, the disk Dk (k is a number from 1 to 100 other than j) corresponding to the middle part of the music, that is, the second video is supplied to the disk drive 34.
[0025]
When the disk Dj is supplied to the disk drive 33 and it is recognized that it is ready to read the segmented video from a predetermined sector address, the central control unit 11 is notified accordingly. In response to this notification, the central control unit 11 starts music performance processing and causes the video database control unit 31 to start playback control of segmented video. The video database control unit 31 controls to switch the divided video input system of the input switching unit 36 to the disk drive 33 side. The MPEG2 decoding unit 37 decompresses / decodes the input MPEG2 data in real time, and gives the reproduced video signal to the video control unit 21.
[0026]
During the playback process of the segmented video that is the first video, the disk drive 34 completes preparation for reading data of the segmented video that is the second video. In synchronization with the end timing of the first video, reading of the segmented video as the second video from the disk drive 34 is started. At the same time, the input switching unit 36 is switched to the disk drive 34 side. In addition, the disk loading mechanism 35 causes the disk Dj mounted in the disk drive 33 to return to the original storage position, and the disk Dl (l is 1 to 1 other than k) on which the third video is recorded. (Number 100) is mounted on the disk drive 33 (of course, if the location of the segmented video for the third video is on the disk Dj, the disk Dj is not returned to the original storage location).
[0027]
The switching of the segmented video from the third video to the fourth video is the same as the switching from the first video to the second video. At this time, if the music to be played next is registered after the music being played, the script data of the music is taken out and the recording location of the segmented video used as the first video is acquired. Then, the disk Dk mounted in the disk drive 34 is exchanged with the disk Dm (m is a number from 1 to 100 other than l) on which the divided video used in the first video of the music is recorded (of course, In some cases, it may not be necessary to exchange the segmented video, which is the first video of the music, on the discs Dk and Dl).
[0028]
The above is the playback control of the background video when the original script data is set for the music to be played. In this embodiment, in the case of “emergency” when the original script data is not set for the music to be played, the next music performance is performed without selecting the alternative script correctly and reloading the disc Di. It has a background video selection function that can start without interruption. In addition, by using the script data of other music pieces that have the same music attributes, that is, the atmosphere and the story are easy to match, it is possible to improve the satisfaction of karaoke users and promote smooth emotion transfer.
[0029]
=== Alternative Script Selection 1 ===
FIG. 3 is a diagram showing an outline of alternative script selection procedure example 1 in the present embodiment, where (a) is a classification code index file, (b) is a song video index file for each singer, and (c) is a procedure flow. It is assumed that the original script data is not yet registered in the script database in the situation where the music number “5627-06” that is scheduled to be played is played. The script database here is generated and managed in the hard disk device 12 of the karaoke device 1, and the singer-specific music video index file 300 can be assumed as an example of the data structure.
[0030]
The karaoke device 1 that has received an input from the karaoke user who has input the music number “5627-06” from the karaoke user first determines whether or not the original script data for the music A is registered in the script database. To do. In this case, paying attention to “5627” in the music number, the singer-specific music video index file 300 associated therewith is referred to as a script database, where the song “06” and the existence of the script data are present. Check for presence. If the original script data corresponding to “06” has already been registered, the first to fourth videos are sequentially connected and reproduced according to the corresponding original script data, and the background video is displayed on the display. Output.
[0031]
On the other hand, when it is determined that the original script data of the music A “5627-06” does not exist, the central control unit 11 of the karaoke apparatus 1 searches for another music having a predetermined classification attribute in common with the music A. Then, the script data set in association with the other music is processed as alternative script data. Therefore, in this embodiment, attention is paid to the classification code and the original song artist as the “predetermined classification attribute” common to the music A, and the music of the original song artist with the artist number “5627” is first classified into the classification code index file 310 ( 3 (a)), it is summarized as “a set of other music pieces having a common classification attribute”.
[0032]
The above-mentioned “classification code” is set to 10 patterns from 1 to 10, for example, and music genres such as enka, pop, rock, jazz, R & B, classic, military song, singing song, nursery rhyme, etc. mean each pattern It is attached. Of course, there are various other classification patterns such as single cut songs, album recording songs, live recording songs, song pattern of songwriter A, song of songwriter B, song of songwriter C, song song of artist, etc. Semantics may be given. The central control unit 11 searches the classification code index file 310 for the music of the original song artist with the artist number “5627” for the music whose classification code is “3”, which is the same as the music A.
[0033]
Subsequently, the script data of the song B, “5672-03”, which is the latest of the searched songs (in this example, the more the associated song is, the more the latest song) is referred to in the song video index file 300 for each singer. The video segment identifiers of the first video in each script data (script candidate 1: 103, script candidate 2: 109, script candidate 3: 101) are recognized. Further, it is determined whether or not the disc on which the segment video corresponding to the recognized video segment identifier is actually set at the playback position of the disc drive 33 or 34. In the embodiment, the disk drive 33 is set with a disk that records a segmented video corresponding to the video segment identifier 101, and the disk drive 34 is set with a disk that records a segmented video corresponding to the video segment identifier 102. It is confirmed that the disc on which the segment video corresponding to the segment identifier 101 is recorded is set in the disc drive 33.
[0034]
Therefore, the central control unit 11 selects script data of candidate 3 having the video segment identifier 101 as the first video, that is, script data “candidate 3 of 5627-03” as alternative script data. Hereinafter, based on the selected alternative script data, the first to fourth segmented videos corresponding to the video segment identifiers 101, 116, 103, 106 are connected to the corresponding discs in the disk drive 33 or 34, respectively. It is played back and output as the background video of song A. According to this embodiment, the original song artist is the same, the music genre is the same, and alternative script data relating to the latest music can be selected and borrowed quickly and easily for other music. Because it borrows the script data of a song that is produced for the same former song artist and the production period is close, and the music genre is the same, the background video played based on this script data feels uncomfortable There will be very few users.
[0035]
=== Alternative script selection 2 ===
FIG. 4 is a diagram showing an outline of alternative script selection procedure example 2 in this embodiment, where (a) is a classification code index file, (b) is a song video index file for each singer, and (c) is a procedure flow. In the alternative script selection procedure example 1 described above, the video segment identifiers of the first video recognized for the script data of the music B “5627-03” (script candidate 1: 103, script candidate 2: 109, script candidate 3) : When the disc containing the segmented video corresponding to 101) is actually set at the playback position of the disc drive 33 or 34, it is determined that the disc is not set in either the disc drive 33 or 34 Is assumed.
[0036]
In such a case, the central control unit 11 has the latest song of the original song artist with the artist number “5627” other than the song B with the “5627-03” among the songs with the same classification code “3” as the song A. The music is searched in the classification code index file 410 for music. The script data of the song C “5672-02” of the searched song is referred to in the song video index file 400 for each singer, and the video segment identifier of the first video in each script data (script candidate 1: 105, script candidate 2). : 103, script candidate 3: 111).
[0037]
Further, it is determined whether or not the disc on which the segment video corresponding to the recognized video segment identifier is actually set at the playback position of the disc drive 33 or 34. In the embodiment, the disk drive 33 is set with a disk that records the segmented video corresponding to the video segment identifier 105, and the disk drive 34 is set with a disk that records the segmented video corresponding to the video segment identifier 102. It is confirmed that the disc on which the segment video corresponding to the segment identifier 105 is recorded is set in the disc drive 33.
[0038]
Therefore, the central control unit 11 selects the script data of candidate 1 of the music piece “5627-02” having the video segment identifier 105 as the first video as alternative script data. Hereinafter, based on the alternative script data, the first to fourth segmented videos corresponding to the segment identifiers 105, 102, 107, and 108 are reproduced by connecting the corresponding discs in the disk drive 33 or 34, respectively. And output as a background image of the music piece A. As described above, by repeating the processing of the alternative script selection procedure 2 until a disc in which the first video that matches the predetermined attribute information is recorded is recognized as being ready for playback in the disc drive. Alternative script data that can be borrowed for the music A is selected.
[0039]
=== Others ===
The video database unit may have two MPEG2 decoding units, input two playback video signals from each decoding unit, and switch the one system to be input to the video control unit. Further, by inserting a video effector (video signal processing unit) or the like in an appropriate signal path, it is possible to switch the video while adding a special effect such as fade-in / fade-out to the segmented video.
[0040]
Various data related to the selection function of the alternative script (script data, various attribute data, etc.) may be data attached to karaoke data or the like, or there is a table associated with the music number, It may be stored in the hard disk device as another data file. Further, a VTS or a sector address may be directly described as attribute data. It suffices if the various data are present in appropriate recording locations so that they can be searched based on the ID of the karaoke song.
[0041]
Furthermore, in this embodiment, a disc (a disc containing only karaoke data or a disc mixed with video data) Di on which karaoke data is recorded is also stored in the disc storage unit 32. The central control unit 11 searches for the corresponding karaoke data in the hard disk device 12 at the time when a performance reservation for a certain piece of music is accepted. Take it out and copy it to the hard disk device 12. At the time of actual music performance, designated karaoke data is taken out from the hard disk device 12.
[0042]
The video database of the present embodiment is composed of a disk loading mechanism using a DVD or CD-ROM as a recording medium and two disk drives. In the first invention, this part is composed of two hard disks. May be. In this case, for example, a device driver for managing replacement so that the sector address of the hard disk is equivalent to the case of handling the sector addresses of a plurality of disks may be interposed.
[0043]
【The invention's effect】
Even if the original script data is not set for a song that is scheduled to be played next, such as a new song immediately after the release, the background data can be borrowed from other songs to match the song and have less discomfort. Playback can be performed quickly and smoothly. As a result, it is possible to promptly provide a background image with a little uncomfortable feeling for karaoke users, even if the song data is not set with script data such as a new song immediately after release.
[0044]
Therefore, the present invention provides a background video system that can easily and quickly select script data that matches a song to be played karaoke and reproduce an appropriate background video when original script data is not set for the song to be played karaoke. Can be provided.
