Abstract
There are provided an information storage medium capable of real-time recording/playback of digital moving picture information, and a digital information recording/playback system using this medium. In a medium that records/plays back data including video data and control information, the control information (DA21 in FIG. 4; RTR_VMG in FIG. 30) includes information (VOBU entry in FIG. 31) for accessing a specific portion (VOBU) of the video data.
Claims5
A machine readable information storage medium for access by an information playback system, the information storage medium embodied as an optical disc comprising:
- a first area in which a video object is recorded;
- and a second area in which control information is recorded,
- the control information including first program chain information and second program chain information,
- the first program chain information relating to a first program chain, the second program chain information relating to a second program chain,
- cells being specified by the control information,
- the first program chain specifying a first playback sequence of one part of the cells, the second program chain specifying a second playback sequence of another part of the cells,
- a first cell of the one part of cells referring to a first region of the video object, a second cell of the another part of cells referring to a second region of the video object,
- a part of the first region being able to overlap with the second region to enable playback of the part of the first region,
- another part of the first region being able not to include the second region,
- one of the cells corresponding to a specific ID, and the specific ID relating to Main video or Sub video, wherein
- the disc is configured to record directory information comprising a first directory for a file of the video object, and a second directory for a file of the control information, the first and second directories being arranged in a same directory, and
- the control information is read and provided to play back the video object by the information playback system, and the video object is accessed according to the read control information.
