<P>PROBLEM TO BE SOLVED: To allow synchronizing of an AV multiplex with another data to be added thereto. <P>SOLUTION: Several data streams contain video and/or 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 the data streams, and in which the descriptors define the arrangement in time for the data streams by means of data sub stream paths. <P>COPYRIGHT: (C)2012,JPO&INPIT |
