Description

  The present invention relates to a recording / reproducing apparatus and a control method therefor, and more particularly to a recording / reproducing apparatus capable of dubbing processing between a plurality of recording media and a control method therefor.

  Some recent digital video cameras use a nonvolatile semiconductor memory card or a hard disk drive as a recording medium. Since these storage media can be accessed randomly, the usability of recording and reproduction can be improved as compared with a digital video camera using a magnetic tape.

  Randomly accessible storage media have become relatively large in capacity due to improved recording density and lower prices of storage media. However, the capacity is limited, and when there is no remaining recording capacity, it is necessary to secure the capacity by deleting the recorded video data. When it is desired to keep the video data, it is necessary to perform a backup operation in which the recorded video is transferred to an external device such as a personal computer or a DVD writer and recorded on another storage medium.

  Recently, there is a digital video camera including a hard disk drive as a fixed storage medium and a recording device (for example, a DVD (Digital Versatile Disc) drive) for recording on a removable medium. Such a digital video camera has a function of dubbing video recorded on a hard disk drive onto a removable medium.

  However, since no operation is accepted during dubbing, including an operation to turn off the power, for example, even if it is desired to take a picture during dubbing, it is not possible to take a picture. In addition, since the recording apparatus using the removable media has a recording speed that is not so high, it takes time to dub a video for a long time.

  In order to cope with such a problem, Patent Document 1 discloses that in a recording / reproducing apparatus having a function of dubbing the contents of a CD to a sequential access recording medium such as a magnetic tape, the dubbing operation is interrupted and then resumed. The technology has been proposed.

JP 2000-195232 A

  However, the recording / reproducing apparatus described in Patent Document 1 does not perform other operations such as new recording while dubbing is interrupted. For this reason, there is no description about the relationship with other operations when dubbing is interrupted for another operation or when the dubbing operation is resumed.

  For example, in a digital video camera that can use a plurality of recording media, a specific example of how operation control is performed when a shooting instruction is given during a dubbing process from one recording medium to another recording medium. There was no investigation.

  The present invention has been made to solve such problems of the prior art. An object of the present invention is to interrupt a dubbing process for execution of another process and then resume it in a recording / reproducing apparatus capable of dubbing video data between a plurality of recording media.

  Another object of the present invention is to provide a recording / reproducing apparatus capable of recording a new video even during dubbing processing.

The foregoing objects, a reproducing means for reproducing the moving image data recorded on the first recording medium, recording means for recording the moving picture data reproduced from the first recording medium to a second recording medium, first designating means for designating moving image data recorded on the recording medium, reproducing means to reproduce a plurality of video data specified by the specifying unit among the moving image data recorded on the first recording medium from the first recording medium Control means for executing a dubbing process for controlling the recording means to record a plurality of reproduced moving image data on the second recording medium, and the control means before the dubbing process is completed. , in response to the dubbing processing of the plurality of moving image data designated by the designating means it has been edited video data uncompleted, to characterized in that eliminate the moving image data edited by the dubbing process of the subject It is achieved by the recording and reproducing apparatus.

Further, when the digital video camera 100 is in an idle state where shooting or playback is not performed, the user can switch the setting of the recording destination and the playback source at an arbitrary timing.

(Recording operation)
Next, a recording (imaging) operation in the digital video camera 100 of FIG. 1 will be described.
When the recording start switch of the operation unit 103 is pressed while the recording mode is set by the operation unit 103, the system control unit 104 controls the recording system circuit unit 110 to start the recording process.

  The system control unit 104 realizes various processes by executing a control program by a CPU (not shown) and controlling each unit. The memory 106 is used as a work area when the system control unit 104 controls the digital video camera 100.

  The imaging signal obtained from the imaging unit 101 is supplied to the image signal processing unit 111 of the recording system circuit unit 110. The image signal processing unit 111 performs A / D conversion on the video signal from the imaging unit 101 to obtain image data, performs white balance processing, color interpolation processing, and the like, and outputs the image data to the image data encoding unit 113 as image data. At this time, the image signal processing unit 111 also performs processing such as sub-sampling as necessary.

  The image data encoding unit 113 encodes the image data from the image signal processing unit 111 according to a standard such as MPEG2, MPEG4, or JPEG, and outputs the encoded image data to the data encoding processing unit 116. Further, the image data encoding unit 113 generates a thumbnail image indicating a representative image of one data file and outputs the thumbnail image to the data encoding processing unit 116.

  On the other hand, audio data from the microphone 102 is output to the audio signal processing unit 112. The audio signal processing unit 112 converts the audio signal from the microphone 102 into digital data, further performs processing such as noise suppression and amplification, and outputs the result to the audio data encoding unit 114. The audio data encoding unit 114 encodes the audio data from the audio signal processing unit 112 according to a standard such as MPEG2 or MPEG4 and outputs the encoded data to the data encoding processing unit 116.

  The data encoding processing unit 116 converts the encoded image data and audio data into a file format conforming to a standard such as MPEG2, MPEG4, or JPEG, and outputs the file format to the recording / reproducing unit 105.

  The metadata generation unit 115 generates data (metadata) indicating shooting information such as shooting date / time, aperture value, shutter speed, and white balance, and outputs the data (metadata) to the data encoding processing unit 116.

  The data encoding processing unit 116 arranges these metadata and the thumbnail image from the image data encoding unit 113 in the file header or footer of the image data and audio data, and outputs them to the recording / reproducing unit 105. In addition, a file name and the like are recorded in the header.

  The management information processing unit 140 acquires information necessary for generating management information conforming to the standard at any time during or before moving image recording from the recording circuit unit 110, and manages and controls the recorded video. Create management information. The management information includes, for example, a disc ID, the total number of video data, playback time, playback time map, management number, video and audio compression encoding method, text, etc., in addition to dubbing interruption information described later.

The recording / reproducing unit 105 records the data output from the recording system circuit unit 110 and the management information from the management information processing unit 140 to a designated one of the HDD 130 or the DVD drive 131 (DVD medium 131a). To do. The recording / playback unit 105 includes a file system for managing writing and reading of data to and from the HDD 130 and the DVD medium 131a.
Management information is also held in the memory 106 as necessary.

(Playback operation)
Next, the reproduction operation in the digital video camera 100 of FIG. 1 will be described.
The digital video camera according to the present embodiment performs playback in either an original playback mode in which video data is played back in the recorded order or a playlist playback mode in which playback is performed according to a playlist created by the user.

The playlist is a list in which the user arbitrarily sets the scene to be played and the playback order. In this specification, “scene” represents a part or the whole of video data, and thus one video data is composed of one or more scenes. Each scene is associated with a thumbnail image that is a representative image. When one video data is composed of a plurality of scenes, a plurality of thumbnail images are stored together with time information (for example, start time, duration) of the corresponding scene in the header of the video data. It is assumed that the digital video camera of this embodiment can designate the target of reproduction or dubbing processing in “scene” units.
The playlist is management information for performing scene playback control. Therefore, even if the playlist is deleted and edited (divided or combined), the video data is not affected.

The user can arbitrarily switch the playback mode by operating the operation unit 103. Note that playback modes other than the original playback mode and the playlist playback mode may be supported. For example, it is possible to correspond to a mode for reproducing a scene that matches a certain condition, such as reproduction by date or reproduction by event.
When a playback mode (for example, an original playback mode) is set by the operation unit 103, the system control unit 104 acquires management information from the memory 106, for example.

  Then, the system control unit 104 controls the reproduction system circuit unit 120 based on the acquired management information, and causes the display unit 107 to display a list of thumbnail images of video data recorded on the HDD 130 or the DVD medium 131a. As described above, the thumbnail image is recorded in the file header of the video data.

FIG. 2 is a diagram illustrating an example of a list display screen (index display screen) in the original playback mode.
On the index display screen 201, thumbnail images 202 to 207 corresponding to scenes of video data recorded on the HDD 130 or the DVD medium 131a are displayed. The thumbnail images 202 to 207 are displayed according to the recording order of the video data. The user operates the operation unit 103 to select an arbitrary thumbnail image, and can notify the designated thumbnail image by, for example, pressing the enter button or the like. When the thumbnail image cannot be displayed within one screen, it is displayed over a plurality of screens. The user can switch and display a plurality of screens by operating the screen moving buttons 208 and 209.

  The system control unit 104 starts reproduction from the scene corresponding to the designated thumbnail image, and then reproduces the video data in the recording order (that is, the display order of the thumbnail images on the index display screen 201). The unit 120 is controlled.

  The reproduction circuit unit 120 reads a scene corresponding to the thumbnail image from the HDD 130 or the DVD drive 131 through the recording / reproduction unit 105. Then, the reproduction system circuit unit 120 decodes the image data and audio data in the read video data, outputs them from the video output terminal 108 and the audio output terminal 109, and displays the reproduced video on the display unit 107.

  More specifically, in the reproduction system circuit unit 120, when a reproduction command is transmitted from the system control unit 104 to the reproduction analysis unit 126, the reproduction analysis unit 126 analyzes moving image information for reproduction.

  Data read from the HDD 130 or the DVD drive 131 by the recording / playback unit 105 is supplied to the data decoding processing unit 125 through the playback analysis unit 126. The data decoding processing unit 125 detects image data and audio data from the read data, and further detects metadata from a file header and footer. Then, the data decoding processing unit 125 outputs the image data to the image data decoding unit 123 and the audio data to the audio data decoding unit 124.

  The image data decoding unit 123 decodes the image data output from the data decoding processing unit 125 and outputs the decoded image data to the image output unit 121. The image output unit 121 converts the decoded image data into a format suitable for processing by an external monitor or other external device, and outputs it to at least one of the video output terminal 108 and the display unit 107.

  The audio data decoding unit 124 decodes the audio data output from the data decoding processing unit 125 and outputs it to the audio output unit 122. The audio output unit 122 converts the decoded audio signal into a format suitable for processing by an external device, and outputs it to the audio output terminal 109.

  FIG. 3 is a diagram showing an example of an index display screen displayed in the playlist playback mode. In FIG. 3, the contents of the playlist that has already been formed are displayed as a list of thumbnail images. A playlist can be easily created by selecting and specifying a thumbnail image corresponding to a scene to be reproduced in an order of reproduction from a list display screen such as an index display screen in the original reproduction mode.

  The playlist information is created by the management information processing unit 140 and then formed in a predetermined format by the recording / playback unit 105. Then, it is recorded as playlist information on the HDD 130 or the DVD medium 131a. In the example of the playlist shown in FIG. 3, it is indicated that the scenes corresponding to the thumbnail images 205, 202, and 207 in FIG. 2 are designated to be played in order from the left.

FIG. 4 is a diagram illustrating an appearance example of the digital video camera 100 of the present embodiment, and the same reference numerals are assigned to the same components as those in FIG.
In the figure, reference numeral 131a denotes a DVD medium that can be attached to and ejected from a DVD drive 131 by a detachable mechanism (not shown). 103a is one of the switches included in the operation unit 103 in FIG. 1, and is a mode dial for switching between power ON / OFF, recording mode and playback mode.

(Dubbing operation)
The operation of the dubbing process in the digital video camera of the present embodiment having the above configuration will be described using the flowchart shown in FIG. In this specification, “dubbing” means a copy or move operation in which video data recorded on one of a plurality of recording media is copied or moved to another recording medium.

  Here, as an example of the dubbing processing operation, an operation when the video data recorded in the HDD 130 is dubbed on the DVD medium 131 a mounted on the DVD drive 131 will be described.

  The digital video camera according to the present embodiment has a dubbing mode as an operation mode. When the dubbing mode is selected by a mode selection dial included in the operation unit 103, the operation in the dubbing mode is started.

  When the operation in the dubbing mode is started, the system control unit 104 checks whether or not the dubbing list has been created by referring to the HDD 130 through the recording / playback unit 105, for example (S401). When there is no created dubbing list, the system control unit 104 performs a dubbing list creation process by the management information processing unit 140 (S402).

Here, a dubbing list creation process will be described with reference to FIG.
First, the management information processing unit 140 causes the display unit 107 to display a dubbing list creation initial screen 502 (FIG. 6). The creation initial screen 502 is a screen for selecting a dubbing list creation method. In the present embodiment, the user has three creation methods for registering any one of (1) all scenes, (2) scenes selected by the user, and (3) scenes registered in the playlist in the dubbing list. It is possible to select.

  (1) When “all scenes” is selected, the management information processing unit 140 registers all scenes in the dubbing list and causes the display unit 107 to display a confirmation screen 505 for dubbing processing content. The confirmation screen 505 provides the user with information related to the dubbing process, such as the thumbnails of scenes registered in the dubbing list (information indicating the contents of the dubbing process), the estimated time required for the dubbing process, and the number of recording media required for the dubbing process. To do. The user can also set a recording rate on the confirmation screen 505.

(2) When “select scene” is selected, the management information processing unit 140 causes the display unit 107 to display a scene selection screen 503.
The scene selection screen 503 is divided into two upper and lower levels, and thumbnails of selectable scenes are displayed in a list on the upper level. In the example of FIG. 5, since all thumbnails cannot be displayed on one screen, the screen is scrolled to the left and right.

  When the thumbnail image displayed in the upper row is selected as a dubbing process target, the management information processing unit 140 registers a scene corresponding to the selected thumbnail image in the dubbing list. Then, the selected thumbnail images are displayed in the order of selection from the lower left. Therefore, in the example of FIG. 5, two scenes are selected as the dubbing process target. When the “decision” button on the scene selection screen is operated and the selection decision is notified, the management information processing unit 140 registers the selected scene in the dubbing list. Then, the management information processing unit 140 displays a confirmation screen 505 on the display unit 107.

(3) When “playlist selection” is selected, the management information processing unit 140 causes the display unit 107 to display a playlist selection screen 504.
The playlist selection screen 504 displays a list of playlists created at that time. The example of FIG. 6 shows a case where three playlists are created. The user selects a desired one from the displayed playlist and notifies the management information processing unit 140 of the desired one. The management information processing unit 140 registers the scene registered in the notified playlist in the dubbing list. Then, the management information processing unit 140 displays a confirmation screen 505 on the display unit 107.

  When the dubbing list is created in this way, the management information processing unit 140 performs dubbing processing setting (S403).

  As described above, on the confirmation screen 505, the user can confirm the recording rate setting, the required number of disks, the estimated dubbing time, and the like. When the “NG” button on the confirmation screen 505 is operated, the management information processing unit 140 displays the creation initial screen 502 again and restarts the dubbing list creation process. On the other hand, when the “OK” button is operated on the confirmation screen 505, the management information processing unit 140 displays a dialog screen 506 for performing final confirmation. When the “cancel” button is operated on the dialog screen, the management information processing unit 140 deletes the dialog screen. On the other hand, when the “OK” button is operated, the management information processing unit 140 confirms the content of the dubbing process according to the setting content at that time, and starts the dubbing process (S404).

  The system control unit 104 reads video data from the HDD 130 through the recording / playback unit 105 according to the dubbing list generated by the management information processing unit 140 (S405), and supplies the video data to the playback system circuit unit 120. The reproduction system circuit unit 120 performs a decoding process on the supplied video data (S406). Then, the decoding result is output from the image output unit 121 and the audio output unit 122 to the image signal processing unit 111 and the audio signal processing unit 112 so as to be recorded in the DVD media 131a.

  The recording system circuit unit 111 performs re-encoding processing in order to record the decoded image and sound on the DVD medium 131a (S407). The re-encoded image and audio signals are recorded on the DVD medium 131a attached to the DVD drive 131 in a predetermined format by the recording / playback unit 105 (S408).

  In the case of performing simple data copying without converting the video data format by re-encoding, the video data read from the HDD 130 through the recording / playback unit 105 is not transferred to the playback system circuit unit 120 but transferred to the DVD drive 131. Just forward. In this case, the processes of S406 and S407 are not performed.

  The system control unit 104 causes the display unit 107 to display a progress screen 507 (FIG. 6) for notifying the user of the progress of the process during the dubbing process. The progress screen 507 includes an interrupt button for the user to instruct to interrupt the dubbing process.

  Further, the system control unit 104 checks whether the recording of the moving image registered in the dubbing list is completed for each predetermined time unit or for each predetermined recording unit, and ends the dubbing mode when the dubbing process is completed (S409). . If the dubbing process has not been completed, the system control unit 104 checks whether a dubbing interruption request has been issued (S410).

  The generation factor of the dubbing interruption request is not particularly limited, but in the present embodiment, it is assumed that the request is for execution of a process that has priority over the dubbing process. Specifically, for example, switching to the recording mode (request for switching to the recording mode) by operating the mode dial 103a during the dubbing process may be performed. Alternatively, it may be a video data recording request. In addition, the dubbing interruption request may be caused by the user's interruption instruction, when the dubbing process is temporarily stopped due to camera drop or vibration, or when the battery level drops when the battery is driven and the dubbing process cannot be continued. Etc. can be illustrated.

  When the dubbing interruption request has been issued, the system control unit 104 causes the display unit 107 to display a confirmation screen for confirming to the user whether to interrupt (stop) the dubbing process. An example of the confirmation screen is shown in FIG.

  When the user operates the “continue dubbing” button on the confirmation screen, the system control unit 104 returns the process to S405 and continues the dubbing process. On the other hand, when the user operates the “dubbing interruption” button on the confirmation screen, the system control unit 104 performs dubbing interruption processing (S411). Depending on the cause of the dubbing interruption request, the dubbing process may be interrupted immediately without displaying the confirmation screen for confirming the interruption of the dubbing process. For example, when the switching operation to the recording mode is performed, the dubbing process can be immediately interrupted so as not to miss the photographing opportunity.

FIG. 7 is a flowchart showing an example of dubbing interruption processing in the present embodiment.
First, the system control unit 104 interrupts the dubbing process (S501). Then, the management information processing unit 140 stores information necessary for resuming the dubbing process (dubbing interruption information) in the memory 106, for example. There is no particular limitation on the content of the dubbing interruption information. For example, dubbing process setting information such as a dubbing list and recording rate, information indicating how far the dubbing process has been performed (where it was interrupted), information for specifying the DVD medium 131a that is the recording destination (disc ID, etc.), etc. It may be. The information indicating the interruption position of the dubbing process is not limited. For example, the amount of data recorded on the DVD medium 131a is counted from the start of the dubbing process as the number of minimum recording units (clusters). May be used as information indicating the interruption position. From the data amount per cluster and the count value, it is possible to specify how much data has been recorded on the DVD medium 131a.

  Next, the system control unit 104 executes a process that is prioritized over the dubbing process, which is a cause of the dubbing interruption request (S503). For example, when the dubbing process is interrupted by an instruction to switch to the recording mode, the digital video camera is placed in a shooting standby state such that the display unit 107 functions as an electronic viewfinder.

  As a result, the user can perform new photographing and recording even during the dubbing process. Thereafter, the system control unit 104 performs the above-described recording process in response to a user operation. When the dubbing process is interrupted and the recording mode is entered, a mark 901 or the like indicating that the dubbing process is interrupted may be displayed on the display unit 107 functioning as an electronic viewfinder as shown in FIG. it can.

  The system control unit 104 monitors the operation unit 103 while executing the process, and checks whether or not there is no user operation for a predetermined time (for example, 5 minutes). For example, after the recording process is completed or when a state in which no user operation is performed for a predetermined time continues without performing the recording process, the system control unit 104 confirms the presence / absence of the dubbing list (S507).

  If the dubbing interruption information, specifically, the dubbing list does not exist (that is, if the dubbing process is not interrupted), the system control unit 104 returns the process to S503. On the other hand, when the dubbing list exists, the system control unit 104 causes the display unit 107 to display an inquiry screen asking the user whether or not the dubbing process needs to be resumed (S509). An example of the inquiry screen is shown in FIG. When the “do not resume” button 602 is operated on the inquiry screen (S511, N), the system control unit 104 confirms with the user whether or not to end the process, and if there is an instruction not to end the process, the process proceeds to S503. return. On the other hand, if there is an instruction to end, the system control unit 104 switches the operation mode of the digital video camera to the dubbing mode (S517), ends the dubbing interruption processing, and advances the processing to S417 (FIG. 5).

  When the “resume dubbing” button 601 is operated on the inquiry screen (S511, Y), the system control unit 104 switches the operation mode of the digital video camera to the dubbing mode (S513). Then, the dubbing interruption process is terminated, and the process proceeds to S413 (FIG. 5). As described above, when the restart of the dubbing process is instructed via the inquiry screen, the system control unit 104 restarts the dubbing process.

Returning to the description of the dubbing mode operation in FIG.
If a dubbing list exists in S401, the system control unit 104 inquires of the user whether to resume the suspended dubbing process in the same manner as in S509. Here, when there is a restart instruction, the system control unit 104 reads dubbing interruption information from the memory 106.

  The system control unit 104 compares the disc ID of the DVD medium 131a inserted in the DVD drive 131 with the disc ID of the DVD medium used when the dubbing process is interrupted from the dubbing interruption information (S414).

  If they match, the dubbing process is resumed according to the dubbing interruption information (S415), and recording from the dubbing interruption position to the DVD medium 131a is continued (S405). On the other hand, if the disc IDs do not match, the system control unit 104 displays an error message prompting the insertion of the DVD medium 131a used for the interrupted dubbing process on the display unit 107 (S416).

  In S412, when the user gives an instruction not to resume the dubbing process, the system control unit 104 causes the display unit 107 to display an inquiry screen as to whether to discard the dubbing list (S417).

  If an instruction to discard the dubbing list is given, the system control unit 104 deletes the dubbing list (S418). At this time, the dubbing interruption information is also deleted. When deleting the dubbing list, if the recording medium (DVD medium) used in the interrupted dubbing process is a write-once medium, the user is notified by a message display or the like that the recorded part cannot be used. May be. Similarly, when a rewritable medium is used, a message for recommending reformatting of the recording medium may be displayed.

  In the present embodiment, the configuration in which the necessity of resuming the interrupted dubbing process is inquired when there is no operation for a predetermined time or when there is a dubbing list when shifting to the dubbing mode has been described. However, an inquiry may be made when a transition operation from the recording mode to another operation mode such as the reproduction mode is performed. Further, it is also possible to make an inquiry when the DVD medium 131a which is a recording medium as a dubbing destination is taken out from the DVD drive 131 and mounted again after that. In this case, the inquiry may be made on condition that the media ID in the dubbing interruption information matches the mounted media ID.

  Thus, according to the present embodiment, even during the dubbing process, the dubbing process can be interrupted for other processes, and the interrupted dubbing process can be easily restarted. it can.

  Further, for example, by interrupting the dubbing process by switching to the recording mode and shifting to a recordable state, it is possible to perform recording without missing the photographing opportunity even during the dubbing process. In addition, since it is inquired whether or not to resume the dubbing process after the recording process or during the next operation in the dubbing mode, the user can surely resume the interrupted dubbing process.

(Second Embodiment)
Next, a second embodiment of the present invention will be described.
The video recording / playback apparatus according to the second embodiment is characterized in that deletion and editing (division or combination) of video data corresponding to a scene registered in the dubbing list is prohibited during dubbing interruption.

  This is because if the dubbing process is interrupted and the user deletes or edits (divides or combines) video data including scenes registered in the dubbing list, the dubbing process based on the dubbing list is resumed. It is because it becomes impossible.

FIG. 11 is a diagram schematically showing the dubbing list and the state of the recording medium when dubbing is interrupted.
It is assumed that scene 1, scene 2, and scene 3 are registered in the dubbing list 801, and the dubbing process is interrupted in the middle of the scene 2. In FIG. 11, the contents of the dubbing list 801 are schematically shown so that the dubbing process interruption position can be easily understood. In FIG. 11, when the dubbing process is interrupted, only the scene 1 among the scenes 1 to 3 to be dubbed is completed on the DVD medium 131a, and the dubbing process is not completed for the scenes 2 and 3.

  In this state, if the video data corresponding to the scene 2 or the scene 3 is deleted or edited (divided or combined), the content of the dubbing list cannot be matched with the video data. Therefore, it is impossible to resume the dubbing process based on the dubbing interruption information. Therefore, in this embodiment, video data corresponding to scenes 2 and 3 for which dubbing processing has not been completed is prohibited from being deleted and edited until completion of dubbing processing or cancellation of dubbing processing is confirmed.

  Here, it is assumed that deletion and editing are prohibited only for video data corresponding to a scene for which dubbing processing has not been completed among scenes registered in the dubbing list. However, deletion and editing may be prohibited for video data corresponding to all scenes registered in the dubbing list, including scenes for which dubbing processing has been completed.

  Specifically, at the start of the dubbing process (FIG. 5, S404), the system control unit 104 has an attribute (protection attribute) that prohibits deletion or editing of video data corresponding to a scene registered in the dubbing list. ).

  Then, during the dubbing process, the system control unit 104 cancels the protection attribute for the video data corresponding to the scene for which the dubbing process has been completed (unless other scenes constituting the same video data are incomplete). Alternatively, as described above, the protection attribute may be canceled collectively after the dubbing process is completed.

  Further, the protection attribute may be added when the dubbing process is interrupted without giving or releasing the protection attribute at the start of the dubbing process or during the dubbing process. Also in this case, the protection attribute may be given only to video data corresponding to a scene for which dubbing processing has not been completed, or the protection attribute may be given to video data corresponding to all scenes registered in the dubbing list. The protection attribute may be released in units of scenes according to the progress of the resumed dubbing process or collectively when all the dubbing processes are completed.

  Here, whether the dubbing process has been interrupted or whether the video data has not been dubbed is determined based on the dubbing interruption information generated by the management information processing unit 140 when the dubbing is interrupted. Can do.

  Deletion and editing prohibited in this embodiment is deletion and editing for the video data itself. Deleting or editing management information that does not affect the video data itself, such as the playlist described above, may not be prohibited.

  FIG. 12 is a diagram illustrating an example of a screen displayed by the digital video camera according to the present embodiment in the original playback mode in a dubbing interruption state, and an example of a screen displayed in response to a user operation.

  When the operation mode is set to the original playback mode, the system control unit 104 refers to the dubbing interruption information, and when the dubbing interruption is in progress, notifies the user of that fact. In the present embodiment, on the thumbnail image list display screen displayed in the original playback mode, the thumbnail image corresponding to the scene registered in the dubbing list is displayed indicating that the dubbing is suspended.

  As shown in FIG. 12, the list display screen 701 includes a dubbing interruption mark 706 indicating that the dubbing process is interrupted in the thumbnail image corresponding to the scene registered in the dubbing list of the interrupted dubbing process. 707 is assigned. The thumbnail images to which the dubbing interruption marks 706 and 707 are assigned may be performed for all scenes registered in the dubbing list, as in the case of the above-described protection attribute assignment, or only for scenes for which dubbing processing has not been completed. You can go.

  Assume that the user operates the operation unit 103 to select a thumbnail image to which a dubbing interruption mark is added and instruct deletion. In this case, the system control unit 104 causes the display unit 107 to display a screen 704 notifying that the scene to be deleted cannot be deleted because it is being used in the interrupted dubbing process.

  When the user changes the operation mode of the digital video camera to the dubbing mode, the system control unit 104 displays the inquiry screen 705 on the display unit 107 as described above. The inquiry screen 705 in FIG. 12 serves both as the inquiry screen for necessity of resuming dubbing processing displayed in S412 in FIG. 5 and the inquiry screen for necessity of deletion of dubbing list displayed in S417.

  When the dubbing process resumption is instructed on the inquiry screen 705, the system control unit 104 resumes the dubbing process as described above (FIG. 5, S413). When the deletion of the dubbing list is instructed, the system control unit 104 deletes the dubbing list (S418), cancels the display of the dubbing interruption marks 706 and 707, and cancels the set protection attribute. Further, as described above, when the dubbing list is deleted, a message corresponding to the recording method of the DVD medium may be displayed.

  If the digital video camera is turned off while the list display screen 701 is displayed, the system control unit 104 displays a notification screen 702 on the display unit 107 for notifying that there is a dubbing process that has not been completed. Perform power-off processing. If the dubbing list remains when the power is turned on, a similar notification screen may be displayed for a few seconds before the initial screen is displayed.

  When the DVD medium 131a used for the interrupted dubbing process is loaded in the DVD drive 131, the removal of the DVD medium 131a may be prohibited. In this case, if the removal operation of the DVD medium 131a used for the interrupted dubbing process is performed while the list display screen 701 is displayed, the system control unit 104 displays a warning screen 703 for prohibiting the removal of the media. 107 is displayed. Note that the prohibition of media removal may be canceled when the dubbing list is deleted.

  It should be noted that if the user wishes to delete or edit video data corresponding to a scene for which dubbing processing has not been completed, it can also be configured to permit it. In this case, on the screen 704, inquiring whether deletion or editing is desired after knowing that the dubbing process cannot be resumed, if there is an instruction to the effect, deletion or editing may be permitted. If deletion or editing is permitted, the dubbing list is deleted and the dubbing process cannot be resumed, or the scene related to the video data that has been deleted or edited is excluded from the dubbing list.

  As described above, according to the present embodiment, when the dubbing process is interrupted, deletion and editing of video data corresponding to all scenes registered in the dubbing list or scenes in which the dubbing process has not been completed is prohibited. This prevents the user from inadvertently deleting or editing video data that has not yet been dubbed, so that dubbing cannot be resumed (completed). Further, it is possible to make the user recognize that the dubbing process is in an interrupted state and prompt the user to restart the dubbing process.

(Other embodiments)
In the above-described embodiment, only the dubbing process from the HDD to the DVD medium has been described, but the present invention can be applied without depending on the recording medium of the dubbing source and the dubbing destination as well as the dubbing process from the DVD medium to the HDD. is there. Note that the recording medium may be a semiconductor memory card or an optical disk that is currently used, or a medium that conforms to a standard that will be established in the future.

  Further, although the digital video camera in which both the dubbing source and the dubbing destination recording medium are built in has been described, either one of the recording media may be externally connected. For example, in a digital video camera with a built-in HDD, the present invention can also be applied to a case where a dubbing process is performed on a DVD medium mounted on an externally connected DVD drive.
