Abstract
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 (PlayItems, 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.
