Multimedia optical disc facilitating branch reproduction to parental lock sections using reduced control information and a reproducing device for said disc

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, and
• wherein, 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.
