The characteristic playback domain of an AV stream is to be reproduced simpl y and reliably without complicating the management. As marks representing characteristic points of an AV stream, a mark of the type indicating a point and a mark of the type indicating a section (duration) are provided. The mar k of the type indicating a point designates a point with a time stamp corresponding to a preset playback timing of the AV stream. The mark of the type indicating a section specifies the domain based on the time stamp of th e playback start point of the preset playback domain of the AV stream and on t he duration as from the playback start point until the playback end point.
