METHOD AND APPARATUS FOR SYNCHRONIZING DATA STREAMS CONTAINING AUDIO, VIDEO AND/OR OTHER DATA

摘要

Several data streams contain video, audio and/or other data. Some of the data streams are pre-recorded in a multiplex on a storage medium while other data streams are located out of the data stream multiplex on the storage medium. The data streams are synchronized using a navigation file (List_of_PlayItems), which comprises descriptors (Play-Items, SubPlayItems) pointing to parts of said data streams, wherein said descriptors define the arrangement in time for said data streams by means of data sub stream paths.
