Abstract
A method for writing an audio/video information stream to an optical disc, and for reading the information from disc. The information stream includes alternative video parts which are recorded in an interleaved manner; an interleaved unit includes angle blocks, each angle block including one portion of each of the alternative video stream parts. For each video portion, entry points are defined. A user is allowed to change from one video stream to another video stream at any moment during the playback of a video portion; the change will be effected at the first entry point after the user command. Thus, it is not necessary to wait until the video portion has been completely played back; thus, it is possible to define large angle block lengths, so that during normal play the jump frequency is reduced.
