Abstract
The characteristic playback domain of an AV stream is to be reproduced simply 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 mark 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 the playback start point of the preset playback domain of the AV stream and on the duration as from the playback start point until the playback end point.
