Abstract:
A multimedia disc made up of a video data storage region and a management information storage region, the video data storage region storing a plurality of video data sequences, each video data sequence having a plurality of video segments of a reproduction period which are recorded in an interleaved manner with a plurality of audio samples, wherein a plurality of sub-pictures and a plurality of control procedures and one audio sample and one sub-picture are reproduced simultaneously with a video segment and wherein each control procedure indicates one video data sequence as a branch address which reflects an interactive operation of a reproduction device during reproduction of a current video data sequence, the management information storage region storing management information comprised of group information which shows which video data sequences have been grouped together to compose a group for which only one of the composing video data sequences is reproduced, a plurality of level identifiers, each of which is assigned exclusively to only one video data sequence in a same group and branch information which indicates, for an arbitrary video data sequence, a video data sequence to be reproduced after termination of reproduction of the arbitrary video data sequence.
