  Here, an exemplary format applicable to the present invention (hereinafter referred to as AVCHD format) will be described. The AVCHD format is a recording format for recording an AV (Audio / Video) stream in which video data and audio data are multiplexed in a predetermined manner on a recordable recording medium. The AV stream recorded on the recording medium is clipped. Can be managed using a playlist.

  For example, ITU-T (International Telecommunication Union-Telecommunication Standardization Sector) recommendation H.264. H.264 or ISO (International Organization for Standardization) / IEC (International Electrotechnical Commission) International Standard 14496-10 (MPEG-4 Part 10) Advanced Video Coding (hereinafter abbreviated as H.264 | AVC) In addition, a bit stream encoded by an encoding method such as MPEG video or MPEG audio and multiplexed in accordance with MPEG2 Systems is referred to as a clip AV stream (or AV stream). The clip AV stream is recorded on the disc as a file by a predetermined file system. This file is referred to as a clip AV stream file (or AV stream file).

  The clip AV stream file is a management unit on the file system, and is not necessarily a management unit that is easily understood by the user. When considering user convenience, a mechanism for playing video content divided into multiple clip AV stream files together, a mechanism for playing only part of a clip AV stream file, and special playback And information for smoothly performing cueing playback must be recorded on the disk as a database.

  FIG. 3 schematically shows a data model defined in the AVCHD format applicable to the present invention. According to this AVCHD format, the data structure is composed of four layers as shown in FIG. The lowest layer is a layer in which the clip AV stream is arranged (referred to as a clip layer for convenience). The upper layer is a layer in which a play list (PlayList) and a play item (PlayItem) for designating a playback position for the clip AV stream are arranged (referred to as a play list layer for convenience). Furthermore, the layer above it is a layer in which a movie object (Movie Object) composed of commands for specifying the playback order and the like for the playlist is arranged (referred to as an object layer for convenience). In the uppermost layer, an index table for managing titles stored in the recording medium is arranged (referred to as an index layer for convenience).

  The clip layer will be described. The clip AV stream is a bit stream in which video data and audio data are multiplexed in the MPEG2 TS (Transport Stream) format or the like. Information regarding the clip AV stream is recorded in a file as clip information (Clip Information).

  The clip AV stream includes an OB stream (Overlay Bitmap stream) that is a graphics stream for displaying subtitles, and an MB stream (Menu Bitmap stream) that uses data (button image data, etc.) used for menu display as a stream. Can be multiplexed.

  A clip AV stream file and a clip information file in which corresponding clip information is recorded are regarded as a group of objects, and are referred to as a clip. That is, a clip is one object composed of a clip AV stream and clip information.

  A file is generally treated as a byte sequence. The content of the clip AV stream file is expanded on the time axis, and the entry point in the clip is designated mainly on a time basis. When a time stamp of an access point to a predetermined clip is given, the clip information file can be used to find address information to start reading data in the clip AV stream file.

  The playlist layer will be described. The playlist is composed of designation of an AV stream file to be reproduced, and a collection of a reproduction start point (IN point) and reproduction end point (OUT point) for designating a reproduction portion of the designated AV stream file. A set of information of the reproduction start point and the reproduction end point is referred to as a play item (PlayItem). A playlist is composed of a set of play items. Playing a play item means playing a part of an AV stream file referenced by the play item. That is, the corresponding section in the clip is reproduced based on the IN point and OUT point information in the play item.

  The object layer will be described. The movie object includes terminal information that links the navigation command program and the movie object. The navigation program is a command (navigation command) for controlling reproduction of a playlist. The terminal information includes information for allowing an interactive operation on the user's player. Based on this terminal information, user operations such as calling a menu screen and title search are controlled.

  The index layer will be described. The index layer is composed of an index table. The index table is a top level table that defines the title of the content recorded on the recording medium. Based on the title information stored in the index table, the reproduction of the recording medium is controlled by the module manager in the system software resident in the player.

  FIG. 4 is a UML (Unified Modeling Language) diagram showing the relationship between the clip AV stream, the clip information (Stream Attributes), the clip, the play item, and the playlist as described above. A play list is associated with one or a plurality of play items, and the play item is associated with one clip. A plurality of play items having different start points and / or end points can be associated with one clip. One clip AV stream file is referenced from one clip. Similarly, one clip information file is referenced from one clip. The clip AV stream file and the clip information file have a one-to-one correspondence. By defining such a structure, it is possible to specify a non-destructive reproduction order in which only an arbitrary part is reproduced without changing the clip AV stream file.

  Further, as shown in FIG. 5, the same clip can be referred to from a plurality of playlists. It is also possible to specify a plurality of clips from one play list. Clips are referenced by IN points and OUT points indicated by play items in the playlist. In the example of FIG. 5, the clip 300 is referred to from the play item 320 of the playlist 310, and the section indicated by the IN point and the OUT point from the play item 321 of the play items 321 and 322 constituting the playlist 311. Is referenced. In addition, the clip 301 refers to the section indicated by the IN point and the OUT point from the play item 322 of the playlist 311, and among the play items 323 and 324 of the playlist 312, the IN point and the OUT point of the play item 323. The section indicated by is referenced.

  The IN point and OUT point set in this way indicate the playback time of the clip. When playing a play item, the clip between the time indicated by the IN point and the time indicated by the OUT point Play.

  The time indicated by the IN point can be calculated based on the recording / playback start time, the value of the frame counter 17 when the IN point is set, and the frame interval. Similarly, the time indicated by the OUT point can be calculated based on the recording / playback start time, the value of the frame counter 17 at the time when the OUT point is set, and the frame interval.

For example, as shown in FIG. 6, the frame counter 17 counts the number of frames from the recording / playback start time. Then, assuming that the frame count values when the IN point and the OUT point are set at a predetermined time from the start of recording / reproduction are the frame count # 1 and the frame count # 2, the time indicated by the IN point and the OUT point is , Based on the mathematical formulas (1) and (2).
IN point = recording / reproduction start time + frame interval × frame count # 1 (1)
OUT point = recording / reproduction start time + frame interval × frame count # 2 (2)

  Next, a method for setting a playback section during moving image recording will be described with reference to a flowchart shown in FIG. Unless otherwise specified, the following processing is performed under the control of the system control unit 14. The user operates the operation unit 16 and presses the moving image recording start / stop key 31 to start moving image recording. In step S11, the shot AV stream file is opened. In step S12, the AV stream file is encoded, and in step S13, the frame counter 17 starts counting frames at the encoding start timing.

  In step S14, it is determined whether the moving image recording start / stop key 31 provided on the operation unit 16 has been pressed by the user and an instruction to stop moving image recording has been issued. If stop of moving image recording is not instructed, it is determined that moving image recording is continued as it is, and the process proceeds to step S15.

  In step S15, it is determined whether or not the playback section start / stop key 32 provided on the operation unit 16 has been pressed by the user to instruct the setting of the IN point (start of section recording). If it is determined that the setting of the IN point has been instructed, the process proceeds to step S16, and the IN point setting process is performed. The time at which the playback section start / stop key 32 is pressed is calculated based on Equation (1), and information on the time indicated by the IN point is stored in the RAM 15. A flag indicating that the IN point has been set is set and stored in the RAM 15.

  If it is determined in step S15 that setting of the IN point has not been instructed, the process proceeds to step S17.
