METHOD FOR RECORDING INFORMATION ON A RECORD MEDIUM, RECORD MEDIUM CONTAINING INFORMATION, AND METHOD AND DEVICE FOR READING INFORMATION FROM A RECORD MEDIUM |
摘要 |
A method is described for writing an audio/video information stream to an optical disc (2), and for reading the information from disc. The information stream comprises a plurality of alternative video parts (VS 1; VS2; VS3) which are recorded in an interleaved manner; an interleaved unit (IU(i)) comprises a plurality of angle blocks (ABj(i)), each angle block (ABj(i) comprising one portion (VSj(i)) of each of the alternative video stream parts (VSj). For each video portion, a plurality of entry points (EP) are defined. A user is allowed to change from one video stream (VS2) to another video stream (VS 1; VS3) 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. |
