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.
Claims7
An information recording method for recording information on an information storage medium that includes,
- (i) a data area for recording a plurality of error correction code blocks, wherein a predetermined number of sectors form each error correction code block, and each of said sectors has a predetermined size,

- (iii) an object recording area located in the data area for recording an object which has a plurality of cells, each cell including a plurality of object units, wherein,
- (iv) said audio/video data is configured to be recorded in at least one of the plurality of object units,
- (v) at least one of said object units corresponds to one or more of the plurality of error correction code blocks,
- (vi) an error correction code block is used as an address unit of said audio/video data such that said audio/video data has an error correction code block address being defined in units of the error correction code block, and
- (vii) start and stop positions of an area including at least one of said object units is defined using the error correction code block address,
- the information recording method comprising the steps of:
- recording the plurality of error correction code blocks into the data area;
- recording the object into the object recording area;
- and
- recording the control information including the plurality of object stream information, the audio/video file information, the information of a recorded unit of video data or audio data in each object information, and the plurality of object information search pointers associated with the plurality of object information.
