Abstract
The present invention is a BD-ROM having AVClips and PlayList information pieces, which are playback paths for the AVClips, recorded thereon. In addition, the BD-ROM also has multiple playback paths and dynamic scenarios recorded thereon. The dynamic scenarios instruct a playback device to play a digital stream using the playback paths. The dynamic scenarios include selection procedures (IF-statement blocks) which cause the playback device to compare a constant and a register-stored value indicating a user'"'"'s age set on the playback device, (PSR(13)), and to select a playback path from among the multiple playback paths according to the result of the comparison.
