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 that reads and writes data from/on a storage medium. The storage medium has stored thereon a first data stream being represented by a video signal that has been encoded by a first encoding process. The data processor includes: a controller, which acquires first playlist information to manage playback of the first data stream; a stream generating section for generating a second data stream by encoding the video signal by a second encoding process, which is different from the first encoding process; and a management section for producing second playlist information based on the second data stream and the first playlist information so as to manage an order in which the second data stream is played back.

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.
