Multimedia optical disc facilitating branch reproduction to parental lock sections using reduced control information and a reproducing device for said disc
First Claim
1. An optical disc comprising:
- a data region for storing a plurality of video sequences composed a plurality of video segments, the video sequences including a plurality of selective video sequences with selection levels which are selectively reproduced depending on the selection levels; and
a management information region for storing sequence information which indicates a reproduction order of video segments included in each video sequence and indicates positions of the video segments included in each video sequence, sequence-link information indicating which video sequence follows each video sequence, group information indicating which selective video sequences compose a group from which one selective video sequence is selectively reproduced, and sequence-attribute information indicating the selection levels of the selective video sequences,wherein at least one of the video segments includes control information which indicates which video sequence is allowed to be reproduced so as to branch from the corresponding video segment disregarding the sequence information and the sequence-link information, andwherein, when any selective video sequence in a group is allowed to be reproduced disregarding the sequence information and the sequence-link information, the control information indicates only one of all selective video sequences in the group as a representative.

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.
