  However, the conventional recording / reproducing apparatus can only record one resume information on one recording medium. Therefore, even in a recording / reproducing apparatus having a plurality of reproduction modes such as original reproduction and playlist reproduction, resume information cannot be held for each reproduction mode. For example, if playback is performed in another mode while resume information about the original playback mode is recorded, the resume information about the original playback mode has been erased.

  In order to solve such a problem, Patent Document 1 discloses a playback apparatus that holds resume information for each of a plurality of playback modes in a memory.

  However, the playback device described in Patent Document 1 stores resume information in a built-in memory and does not record it on a recording medium. Therefore, resume information stored for a removable recording medium such as a DVD cannot be used at all when the recording medium is played back by another playback device, and is not user-friendly.

The present invention has been made to solve such problems of the prior art.
An object of the present invention is to provide a recording / reproducing apparatus capable of storing resume information in consideration of storage of resume information for each playback mode and use of resume information between different apparatuses, and a control method thereof.

  The above-mentioned purpose is to stop the video data recorded on the recording medium in the playback mode selected from a plurality of playback modes, information on the position where the playback of the video data was stopped, and the playback of the video data. Means for generating resume information in association with information for specifying the playback mode at the time, and when the playback mode when the playback of the video data is stopped is a predetermined playback mode, the resume information is stored in the recording medium. And recording means for recording resume information in a storage device different from the recording medium when the reproduction mode when recording and stopping the reproduction of the video data is not a predetermined reproduction mode. Achieved by a playback device.

  In addition, the above-described object is to read out video data recorded on a recording medium and reproduce it in a reproduction mode selected from a plurality of reproduction modes, information on a position where reproduction of the video data is stopped, and reproduction of the video data. Generating resume information in association with information specifying the playback mode when the playback is stopped, and when the playback mode when the playback of the video data is stopped is a predetermined playback mode, the resume information is displayed. And recording the resume information on a storage device different from the recording medium when the playback mode when recording on the recording medium and the playback of the video data is stopped is not a predetermined playback mode. This can also be achieved by the control method of the recording / reproducing apparatus.

The digital video camera 100 according to the present embodiment records image and audio data obtained as a single file (video data file) after a recording start instruction is input until a recording stop instruction is input. It shall be.

  Audio data from the microphone 102 is input to the audio signal processing unit 112. The audio signal processing unit 112 converts the audio data from the microphone 102 into digital data, further performs processing such as noise suppression and amplification, and outputs the processed data to the audio data encoding unit 114. The audio data encoding unit 114 encodes the audio data from the audio signal processing unit 112 using, for example, the MPEG2 system and outputs the encoded data to the data encoding processing unit 116.

  The metadata generation unit 115 generates data (metadata) indicating shooting information such as the shooting date and F value, and outputs the data (metadata) to the data encoding processing unit 116.

  The data encoding processing unit 116 arranges data from the image data encoding unit 113, the audio data encoding unit 114, and the metadata generation unit 115 into a data stream in a predetermined format, and outputs the data stream to the recording / reproducing unit 105. . At this time, the data encoding processing unit 116 arranges the metadata from the metadata generation unit 115 and the thumbnail image from the image data encoding unit 113 in the header or footer of the encoded image data or audio data. . In addition, a file name and the like are recorded in the header.

  The recording circuit block 110 notifies the management information processing unit 128 of information relating to the generated image data, audio data, and the like while performing the recording operation. Based on this information, the management information processing unit 128 generates management information including playback control information and supplies the management information to the recording / playback unit 105. In the present embodiment, the management information is, for example, the number of video data files recorded on the recording medium 106, the playback time, the management number, and the encoding format of video and audio in addition to the playback control information (resume information). , Text information and so on.

  The recording / reproducing unit 105 arranges the data stream from the data encoding processing unit 116 into a format for recording on the recording medium 106 and records the data stream on the recording medium 106. Further, the recording / reproducing unit 105 records the management information generated by the management information processing unit 128 on the recording medium 106 as a management information file according to the setting.

(Playback operation)
Next, a normal playback operation in the digital video camera 100 of this embodiment will be described.
When the playback mode is set through the operation unit 103, the system control unit 104 reads the management information from the recording medium 106 and causes the management information processing unit 128 to analyze the management information.

  The system control unit 104 controls the recording / playback unit 105 and the playback system circuit block 120 based on the analysis result of the management information, and displays an index screen that displays a list of thumbnail images that are representative images of moving images recorded on the recording medium 106 Is displayed on the display unit 107. The user confirms the thumbnail images displayed as a list on the index screen displayed on the display unit 107 and operates the operation unit 103 to select a thumbnail image, thereby selecting a file to be reproduced. The system control unit 104 starts playback control of video data corresponding to the thumbnail image selected from the index screen through the operation unit 103.

  The system control unit 104 causes the recording / playback unit 105 to read video data to be played back from the recording medium 106. The recording / playback unit 105 sequentially supplies the read video data to the playback system circuit block 120.

In the reproduction system circuit block 120, the video data read from the recording medium 106 by the recording / reproducing unit 105 is given to the reproduction analyzing unit 126. The reproduction analysis unit 126 separates the data reproduced by the recording / reproduction unit 105 into video data and audio data, and other data such as metadata. Then, the video data and audio data are output to the data decoding processing unit 125. In addition, data other than video data and audio data is output to the system control unit 104.
The data decoding processing unit 125 detects image data and audio data included in the reproduced data, and outputs the image data to the image data decoding unit 123 and the audio data to the audio data decoding unit 124, respectively.

  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 the video output terminal 108 or 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.

Next, playback processing according to the playback mode will be described.
The digital video camera 100 of this embodiment can play back video data according to a plurality of playback methods (playback modes). Here, the reproduction mode means a method (reproduction control method) for controlling which video file is reproduced in what order among a plurality of video files recorded on the recording medium 106.

  In the present embodiment, there are two playback modes: an original playback mode in which video data is played back in the order recorded in the recording medium 106, and a playlist playback mode in which video data arbitrarily selected by the user is played back in an arbitrary order. It shall be equipped with. The user can arbitrarily switch the playback mode by operating the operation unit 103. Here, the original reproduction and the playlist reproduction are listed here, but it goes without saying that other reproduction modes such as the above-described reproduction mode by date and reproduction mode by event may be provided.

  FIG. 2 is a diagram showing an example of an index screen displayed when the original playback mode is set. On the index screen 201, thumbnail images 202 to 207 of each moving image recorded on the recording medium 106 are displayed. The thumbnail images 202 to 207 are arranged in the order in which moving images are recorded. The user can view the video data instructed to be reproduced by operating the operation unit 103 to select a desired thumbnail image and instructing the reproduction.

  The system control unit 104 can start viewing the specified video data and can start playback from an arbitrary position in the recorded order. After the playback starts, the moving image is displayed in the order of thumbnails (recording order). Will be played.

FIG. 3 is a diagram showing an example of an index screen displayed when the playlist playback mode is set.
For example, the user can generate a playlist by selecting desired thumbnail images in the desired order from the index screen 201 as shown in FIG. The index screen 301 in FIG. 3 shows a state in which thumbnail images 302 to 304 that are representative images of video data included in the already generated playlist are displayed in a list. The thumbnail images 302, 303, and 304 are the same as the thumbnail images 205, 202, and 207, and this playlist is reproduction control information that reproduces video data corresponding to the thumbnail images 205, 202, and 207 in this order. Indicates.

  The generated playlist (video data to be reproduced and information indicating the order thereof) is generated by the management information processing unit 128, formed in a predetermined format by the recording / reproducing unit 105, and recorded as reproduction control information on the recording medium 106. The

(Resume information recording settings and processing)
In the present embodiment, resume information is recorded in the recording medium 106 or the memory 127 according to the setting.
Specifically, in the present embodiment, the recording destination can be set according to the reproduction mode when the resume information is generated.

  For example, if “Resume information generated in the playlist playback mode is recorded in the recording medium 106” is set, the resume information generated in the playlist playback mode is recorded in the recording medium 106 and stored in the memory 127. Not recorded. On the other hand, resume information generated in other playback modes, for example, the original playback mode, is not recorded in the recording medium 106 but is recorded in the memory 127.

  In the present embodiment, it is also possible to set whether to record resume information on the recording medium 106. In the case where the resume information is not recorded on the recording medium 106, the generated resume information is not recorded on the recording medium 106 regardless of the reproduction mode. In this case, it may be recorded in the memory 127 or may not be recorded in the memory 127.

When recording resume information on the recording medium 106, if the management information processing unit 128 that generates the resume information is generated in a format conforming to the standard, the recording medium 106 may be played back by another device that conforms to the standard. Resume playback is possible. Of course, even when the recording medium 106 is a fixed recording medium, it is needless to say that resume reproduction is realized by copying to a recording medium of another device compliant with the standard via a network, for example.
On the other hand, the resume information recorded in the memory 127 cannot be taken over by another player, and is effective only when it is self-reproduced.

  By adopting such a form, even when only one resume information can be held in one recording medium, the resume information desired by the user is recorded in the recording medium 106. Therefore, even when the recording medium 106 is reproduced by another device (which can interpret the resume information), the resume reproduction is correctly performed from the previous continuation.

  In addition, since other resume information not recorded on the recording medium 106 is recorded in a storage device (memory or the like) in the apparatus, resume reproduction for each reproduction mode is possible in self-reproduction, which is highly convenient.

  In the present embodiment, one resume information is recorded on one recording medium, but this is based on a restriction by the current standard. Therefore, when it is standardized to record a plurality of resume information on one recording medium, the number of resume information to be recorded can be increased within the range of the standard.

(Resume information recording setting)
FIG. 4 is a flowchart for explaining resume information recording setting processing in the digital video camera 100 of the present embodiment.
The resume information recording setting process is executed at an arbitrary timing as well as when the execution of the resume information setting is instructed by the operation of the menu screen through the operation unit 103, similarly to the setting of other parameters in the digital video camera 100. sell.

  First, the system control unit 104 displays a resume information setting screen on the display unit 107 through the image output unit 121 (S701). It is assumed that data (GUI data) for displaying a user interface screen (GUI screen) including a resume information setting screen is stored in advance in the memory 127, for example. The system control unit 104 can read the GUI data as necessary, supply the GUI data to the image output unit 121, and display the GUI screen on the display unit 107.

FIG. 5 is a diagram showing an example of a resume information setting screen 600 displayed by the digital video camera 100 in the present embodiment.
The user can perform the recording setting of the resume information by operating the resume information setting screen 600 that is a user interface screen through the operation unit 103.

As described above, in the present embodiment, it is possible to set whether to record resume information on the recording medium 106 and, in the case of recording, in which playback mode the resume information generated is recorded. It is. In the example of FIG. 5, two playback modes, the original playback mode and the playlist playback mode, are shown as selectable playback modes, but it goes without saying that other playback modes may be included in the options.
However, when the resume information to be recorded on the recording medium 106 is in a format conforming to the standard, only the playback mode supported by the standard is displayed as an option.

  The system control unit 104 waits for the user to select an option by operating the resume information setting screen 600 (S702). When the selection is made, the system control unit 104 checks whether “do not save” is selected (S703).

  If “do not save” is selected, the system control unit 104 confirms through the recording / playback unit 105 whether the resume information has already been recorded on the recording medium 106 (S710). If resume information is recorded, the resume information is copied to the memory 127, and then the resume information recorded on the recording medium 106 is deleted (S711). That is, the system control unit 104 moves the resume information recorded on the recording medium 106 to the memory 127. On the other hand, when the resume information is not recorded on the recording medium 106, the resume information setting that the resume information is not recorded on the recording medium 106 is stored in the memory 127, for example, and the process is terminated.

  When one of the playback modes is selected on the resume information setting screen 600, the system control unit 104 stores the resume information setting in which the selected playback mode is associated with the recording destination (recording medium 106) in the memory 127. (S704).

  Next, the system control unit 104 checks whether the resume information has already been recorded on the recording medium 106 through the recording / reproducing unit 105 (S705). If not recorded, the process proceeds to S708.

  If it is recorded, the system control unit 104 checks in which playback mode the resume information recorded is the resume information (S706). If the resume information is for a playback mode different from the playback mode selected by the user, the system control unit 104 moves the resume information recorded on the recording medium 106 to the memory 127 (S707). If resume information about the playback mode selected by the user is recorded on the recording medium 106, the process directly proceeds to S708.

  Next, the system control unit 104 checks whether the resume information about the playback mode selected by the user exists in the memory 127 (S708). If it exists, the recording / playback unit 105 copies the resume information from the memory 127 to the recording medium 106, and erases the resume information from the memory 127 (S709). That is, the resume information is moved from the memory 127 to the recording medium 106. When the resume information about the playback mode selected by the user does not exist in the memory 127, the recording setting process is terminated.

(Resume information recording process)
Next, the resume information recording process according to the recording setting will be described.
FIG. 6 is a flowchart for explaining the recording process of resume information in the digital video camera 100 of the present embodiment.
The resume information recording process is executed when a stop of moving image reproduction is instructed from the operation unit 103 during reproduction of the moving image.

  First, the system control unit 104 executes a predetermined reproduction stop process (S501). When the reproduction stop process is completed, the system control unit 104 refers to the memory 127, for example, confirms the content of the resume information recording setting, and confirms the current reproduction mode (S502).

Here, if the recording setting is a setting for not recording the resume information on the recording medium 106, the system control unit 104 ends the resume information recording process (S503).
When the setting for recording the resume information is made, the system control unit 104 controls the management information processing unit 128 to generate the resume information (S504).

  The digital video camera 100 of the present embodiment can hold resume information for each playback mode. The resume information is information indicating a position where reproduction is stopped (or a reproduction restart position) by a user operation or the like during moving image reproduction, and is associated with at least the reproduction mode. By referring to the resume information at the next playback and starting playback from the stop position, it is possible to provide the user with viewing from the previous continuation. Note that the resume information may include information other than the data described above, for example, a file number or an address. In addition, by including the unique information of the removable recording medium 106, it becomes possible to manage the resume information for each recording medium.

  Note that the information indicating the playback stop position can be acquired through the recording / playback unit 105 when the resume information is generated, and information (for example, time information from the beginning) indicating the playback position from the recording / playback unit 105 during the playback process. You may make it receive at any time. Since any known method can be used for obtaining the playback stop position, further details are omitted.

  Next, the system control unit 104 checks whether or not the current playback mode is the playback mode set in the recording setting for resume information (S505). If the current playback mode is set as a playback mode for recording resume information on the recording medium 106, the system control unit 104 records the resume information on the recording medium 106 using the management information processing unit 128 and the recording / playback unit 105. (S506). If the current playback mode is not set as a playback mode for recording resume information on the recording medium 106, the system control unit 104 acquires the resume information from the management information processing unit 128, and associates the current playback mode with the current playback mode. It records in 127 (S507). When the resume information is recorded in the memory 127, it is possible to record and use the resume information for each recording medium 106 by recording the removable recording medium 106 in association with the identifiable unique information. is there.

FIG. 7 is a diagram schematically showing processing when a stop instruction is issued during reproduction according to the playlist shown in FIG.
When the user stops playback, the system control unit 104 performs index screen display processing in the playback stop processing of S501.

  Here, since reproduction according to the playlist shown in FIG. 3 is interrupted, an index screen 401 having substantially the same contents as the index screen shown in FIG. 3 is displayed. It is assumed that each of the three video data included in the playlist has a length indicated by the timeline 403.

  The example of the list display screen shown in FIG. 7A shows a case where the video display 2 is stopped during playback. It is assumed that the resume information is set to be recorded. Therefore, resume information is generated in the processing after S504, and is recorded in the recording medium 106 or the memory 127 according to the recording setting.

  In the present embodiment, when displaying a thumbnail image corresponding to video data for which playback has been stopped halfway, a resume mark 402 is added to the thumbnail image of the video data corresponding to resume information.

In the case of the processing of FIG. 6, when the resume information is recorded, the resume mark 402 is added to the thumbnail image 303 of the video data corresponding to the resume information. The resume mark 402 is displayed not only on the index screen displayed when playback is stopped, but also on the normal list display screen shown in FIGS. In this case, when displaying the list display screen, the presence / absence of the corresponding resume information is confirmed. If there is resume information, the resume mark 402 is added to the corresponding thumbnail image.
Thus, if the user selects a thumbnail image to which the resume mark 402 is added and instructs playback, the user can view from the previously stopped position.

  FIG. 7B shows a specific example of the resume information 404. Information indicating the playback mode at the time of stop (mode number) and information indicating the playback stop position (here, the elapsed time from the first moving image, In other words, it is constituted by the regenerated time). As described above, when management for each recording medium is performed, unique information of the recording medium 106 is further associated. Also, as described above, other information may be included.

  In the present embodiment, it has been described that only the resume information of the playback mode selected by the user is recorded as management information recorded on the recording medium 106. However, it is also possible to configure so that only resume information of a specific playback mode is recorded on the recording medium 106 in advance, not user settings.

  The newly generated resume information is always recorded on the recording medium 106, and the past resume information is moved to the memory only when the resume information is different from the resume information recorded on the recording medium 106 in the past. It is also possible to configure as described above. As a result, it is possible to avoid erasing resume information for a playback mode different from that due to new resume information as in the prior art.

  As described above, even if it is set not to record to the recording medium 106, it may be recorded in the memory 127. In this case, the system control unit 104 generates the resume information in S504 before S503, and in the case where the resume information is not recorded on the recording medium 106, the resume information is stored in the memory 127 in the same manner as in S507. Record.

  In the present embodiment, the case where the present invention is applied to a digital video camera as an example of a recording / reproducing apparatus has been described. The present invention can be applied to any device capable of reproduction.

As described above, according to the present embodiment, the recording destination of the resume information can be selected from the recording medium or the storage device inside the apparatus according to the reproduction mode.
As a result, the resume information that the user wants to use on other devices can be recorded on the recording medium. On the other hand, when playback is performed on the device that generated the resume information, the resume information on other playback modes is used. Resume playback is also possible. In particular, in a situation where the number of resume information that can be recorded on one recording medium is limited by the standard, it is possible to achieve both convenience and compatibility between apparatuses having different resume information.
