Abstract:
A recording disk comprising:a data area where data to be decoded is recorded;control data for reproducing said data from said data area;a multi-scene program, stored in said data area, representing a video program and having a plurality of optionally selectable scenes recorded in recording tracks;video signals representing said plurality of optionally selectable scenes being recorded such that said plurality of scenes are divided, respectively, into interleaved units at a branch point where switching from one scene to another is allowed;each of said interleaved units including a plurality of video packets obtained by compressing video data in the form of packets, a plurality of audio packets obtained by compressing audio data in the form of packets, a navigation pack located at a start position and serving as said control data, and video frame data situated first in each of said interleaved units and used as a reference when data compressed in accordance with a frame-correlated compression scheme is decoded,wherein said interleaved units corresponding to the respective scenes are recorded on recording tracks in a physically mixed state,wherein the number of divisions of each of said branch scenes are determined to satisfy predetermined conditions such that there is no picture pause when those of said interleaved units corresponding to a selected scene are reproduced, andwherein said navigation pack describes information indicative of the mixed-state arrangement of interleaved units of different scenes, addresses indicative of next interleaved units representing jump destinations of each scene, and sizes of said next interleaved units.
