  • Patent number: 6516139
    Abstract: A system stream contiguous reproduction apparatus to which are input one or more system streams interleaving at least moving picture data and audio data, and system stream connection information includes a system clock STC generator for producing the system clock that is used as the system stream reproduction reference clock. The system stream contiguous reproduction apparatus further includes one or more signal processing decoders that operate referenced to the system clock STC, decoder buffers for temporarily storing the system stream data transferred to the corresponding signal processing decoders, and STC selectors for selecting a system clock STC referenced by the signal processing decoders when decoding the first system stream, and another system clock STC referenced by the signal processing decoders when decoding a second system stream reproduced contiguously to the first system stream.

  • Patent number: 6181872
    Abstract: An interleaving method for generating a bitstream from plural video objects containing compressed video data by arranging in the presentation order, wherein interleaved data blocks in which plural video objects are contiguously arrayed using interleaved units each longer than the shortest read time ILVUMT such that the video object presentation start and end points are aligned. The ratio between the presentation times of video objects with the shortest presentation time and video objects other than those with the shortest presentation time is within a range obtained from the shortest read time ILVUMT, the maximum jumpable distance JM, and the smallest control unit. contiguous data blocks wherein the presentation start points and end points of the video objects arrayed therein are not aligned.
