摘要： A data processor records an audio frame corresponding to an audio gap interval at a connection point, as well as the audio playback control information, in a post recording area. The audio is reproduced so as to include the audio frame at the connection point. The audio is also reproduced while being faded in and faded out in accordance with the audio playback control information. As a result, when an MPEG program stream stored on a disk is played back by making a play list with the connection point re-encoded, seamless playback is guaranteed without discontinuing the audio at all.
摘要翻译：数据处理器在后记录区域中记录与连接点处的音频间隔间隔对应的音频帧以及音频播放控制信息。再现音频以便在连接点包括音频帧。音频也被再现，同时根据音频播放控制信息褪色和淡出。结果，当通过使连接点重新编码的播放列表来播放存储在盘上的MPEG节目流时，保证无缝播放而不中断音频。

摘要： The data processor of the present invention can play back video and audio synchronously from an optical disk, on which video and audio data are stored in different areas. Each area consists of one or more unit areas. The data processor includes: a playback control section for giving instructions on how to read the video and audio data and how to play back the video and audio based on the read data; a head for reading the data from one of the unit areas after another in accordance with the instructions; and audio and video buffers for retaining the audio and video data read. The playback control section instructs that the audio data be read from a predetermined one of the unit areas to the audio buffer memory, and then instructs that the video data, which is to be played back over first and second periods of time, be read from a number n (where n is an integer equal to or greater than two) of unit areas to the video buffer. The first period of time is (n+2) times as long as the maximum amount of time to move the head, and the second period of time is taken to read the audio data from the next unit area.

摘要： A data processor includes a stream assembling section which divides video and audio data into a plurality of packets, and makes a plurality of data units, in each of which a video packet representing a fraction of the video data and an audio packet representing a fraction of the audio data are multiplexed together to generate a data stream composed of a plurality of data units; and a writing section for writing the data stream on a storage medium. The stream assembling section determines what video packets and audio packets are included in each data unit, and if a portion of audio data, which is associated with the video data stored in a predetermined data unit, is missing from the predetermined data unit, then copied data, obtained by copying partial audio data including at least that missing portion of the audio data, is put into the data stream.

摘要： Each of a first data stream in a first format and a second data stream in a second format is an arrangement of a plurality of data units, each including compressed and encoded video data. In the first and second formats, first and second time ranges are respectively set to define a permissible variation in the video playback duration of the respective data units. The method includes the steps of: receiving a content representing the video; generating the compressed and encoded video data of the content; making the data units out of the video data such that the playback duration of each said data unit falls within both of the first and second time ranges; and recording the first data stream, including the data units, on the storage medium.

摘要： For multiple moving-image recorded on a storage medium, one piece of meta-data or each of multiple pieces of meta-data recorded for a part or all of the moving-image is managed by meta-data indices. A meta-data index keeps invalidity information indicating whether a piece of meta-data is going to be invalid and validity information indicating validity of the current piece of meta-data in the same form, when operations such as editing and processing are performed on a part or all of a moving-image that is an object of a piece of meta-data. When cutting-out occurs on a section of a moving-image that is an object of a piece of meta-data and the piece of meta-data cannot be recalculated, the invalidity information is copied to the validity information. In this manner, a meta-data added to the moving-image can be adapted and be used after the moving-image is edited.
