A data recording structure supporting an AVCHD format is provided. The data recording structure allows a playing process, an editing process and a write-once recording process to be quickly performed. When data recording is performed in a data recording format having a layered management structure such as an AVCHD format, identification information is stored in an index file containing index information for record data. The identification information is needed to perform one of the playing process on the record data, the editing process on the record data and the write-once recording process on data. This arrangement eliminates the need for reading a variety of files and retrieving information when one of the record data playing process, the record data editing process and the write-once recording process is performed. Each process is thus quickly performed.

An information processing apparatus may include a controller for controlling the reproducing of a menu based on content recorded on a information recording medium. The controller may control producing a menu that allows the content to be selected and reproduced by chapter, the chapter defined by a mark as content delimitation information set in play list information corresponding to the content recorded on the information recording medium and recording the menu on the information recording medium.

Recording of video data is enabled by a management structure of a clip which is compatible with a BD-ROM standard. In accordance with the recording starting operation, the recording of a stream in which the video data and audio data have time-divisionally been multiplexed on a packet unit basis onto a recording medium is started. In accordance with the recording stopping operation, the stream stored in a buffer is written as a stream file onto the recording medium and a clip information file corresponding to the stream file is formed. A play item showing the whole clip information file is formed and added to the existing play list on the recording medium. A mark is stamped to the play list at time corresponding to an IN point of the play item. Subsequently, the play item which is formed in association with the recording start and stop is similarly further added to the existing play list and the mark is further stamped at the time corresponding to the IN point.

A configuration is provided which realizes efficiency of playback and editing of recorded data in an information recording medium. Recording is performed of GOP attributes, as mark management information corresponding to a PLM (=EM) mark serving as playback start point information stipulated in the AVCD format, indicating whether or not a GOP including the mark is a GOP needing decoding information of another GOP at the time of decoding processing of the GOP, and playback and editing are performed referencing these information, thereby preventing decoding unnecessary in playback processing, and enabling editing without leaving data unnecessary in editing processing.

Non-destructive editing of a movie stream recorded with management information attached thereto according to a predetermined standard format is performed. First, an entry for desired content from among real play lists is added to a virtual play list. In the virtual play list, a playback content editing operation is performed. The process of editing a virtual play list that does not contain content of an entity involves non-destructive editing that does not accompany editing of the content of an entity. In addition, non-destructive editing of a virtual play list only requires the updating of a management information file, and only involves an increase in the used amount of the recording medium by the additional amount of the management information even if a playback section is copied, thus improving user convenience.

An apparatus and a method for quickly starting recording seamless-playable data are provided. At the end of recording a preceding record content, identification information of a clip information file for a subsequent record content to be recorded next is recorded in an attribute information storage file set for the preceding record content. More specifically, a clip information file for a subsequent chapter is reserved at the end of recording of a preceding chapter, and an identifier of the clip information file is recorded in the clip information file for the preceding record chapter. Through the prior reservation process of the clip information file, an updating process for updating the clip information file at the start of recording of the subsequent chapter becomes unnecessary. Data recording, such as a photographing operation of a video camera is thus quickly started.
摘要:
A movie stream recorded on a recording medium with accompanying management information according to a predetermined standard format is edited while satisfying an upper limit condition.When the number of play items or the number of playlist marks in a playlist has reached or approached the upper limit condition, last chapter information in the playlist is moved to the beginning of a subsequent playlist or a newly created playlist. Furthermore, in a case where there exists a margin against the upper limit condition regarding the number of play items or the number of playlist marks as one playlist even if contents of two or more adjacent playlists are combined, the playlists are integrated to reduce the number of playlists on the recording medium.
