- the recording / playback function for 821 As shown in Fig. 8, it has an input hole for the portable device recording media 841, and also has the recording / playback function for the portable device recording media 841. I have.
- the video data shot by the portable video recording device 831 is recorded in the portable device data format according to the directory file configuration shown in FIG. Then, the plurality of recording media 841 for mobile devices created in the same manner are sequentially inserted into the integrated video data file playback device 811 to start the recording operation on the integrated video data recording media 8221.
- This will enable implementation Management information including playback control information by the integration method described in Embodiment 1:
- the integrated video data is recorded on the integrated video data recording medium 8 21.
- the integrated video data recording medium 8 2 1 When the integrated video data recording medium 8 2 1 is started to be played back by the integrated video data file playback device 8 1 1, as described in Embodiment 1, the data for each of the plurality of portable device storage media 8 4 1 is integrated video. Since the data file is recorded as a playlist which is playback control information in the data format of the data file playback device 811, three playlists (playlistl, playlist2, playlist3) are displayed on the video display device 851.
- the user can easily perform playback of the recording media 841 for the portable device before integration in the integrated video data file playback device 811.
- the data format recorded on the integrated video data recording medium 8 21 conforms to the data format for recording and playback by the integrated video data file playback device 8 11. If the data format is a reproducible reproducing device, the same reproducing operation is guaranteed.
- the integrated video data file reproducing device 811 executes the operation. According to the operation described in the first embodiment, the directory file structure and directory name of “Cardl” before integration are restored and recorded on the portable device recording medium 841.
- the integrated video data file playback device 8 11 according to Embodiment 2 enables the viewing and editing of video materials according to the management information before integration, and the writing to other media according to the above operation. It is to solve the problem.
- Embodiment 1 an example in which data recorded by a portable device is converted and recorded on a recording medium of the stationary device in a state where data recorded by the stationary device is not recorded on the recording medium was explained. If the data recorded by the stationary device already exists on the recording medium of the stationary device and the playback control information already exists for the data, the data recorded by the portable device is converted. Then, when recording on the recording medium of the stationary device, the originally existing playback control information and the newly added playback control information will be mixed in the management information file 211.
- the title information corresponding to each piece of reproduction control information is specified in the management information file 211, and further, it is specified for data originally recorded on the stationary device.
- Fig. 9 shows only the part related to the playback control information in the data format of the management information file 211 on the recording medium for stationary equipment.
- the storage areas 911, 912, and 913 are configured to be added.
- the playback control information corresponding to Playlist 1 is the playback control information already defined for the data recorded by the stationary device
- the playback control information corresponding to Playlists 2 and 3 is The playback control information specified when the data recorded by the device is integrated with the data already existing in the medium B312.
- the stationary device records the playback control information, that is, the title of the playback control information corresponding to Playlist l is named, for example, "Disk No. 1"
- the data recorded on the portable device is integrated.
- the titles of the generated playback control information that is, the playback control information corresponding to Playlists 2 and 3 are, for example, "Card No. 1" and "Card No. 2".
- the recording medium used for data recording in the portable device has been described as a recording medium in the form of a memory card having a built-in flash memory, but is not limited to this.
- the recording medium used for data recording in the stationary device has been described as a rewritable disk-type recording medium such as a TWD (Digital Versatile Disc) -RAM disk, but is not limited to this. ,. It goes without saying that the present invention is effective regardless of the recording medium.
- the present invention converts the directory file configuration information of a plurality of recording media units before the integration into reproduction control information in the data format of the integrated management information file in the integrated management information file and records it. It allows viewing and editing of video materials according to the management information before integration, and writing to other media.
