Patent ID: 6888895

Claim:
A method for encoding video data consisting of one or several bitstreams according to the MPEG- 4 standard, characterized in that a specific alignment/fragmentation mechanism is chosen, according to which, when said video bitstreams are encoded using the syntax mode corresponding to a fragmentation of the Video Object Planes (VOPs) contained in said video data into Video Packets (VPs) and of Video Packets into Data Partitions (DPs), a Video Data Partition is mapped into one or more Sync Layer packets (SL packets), the first Video Data Partition start is always mapped to an SL packet start even if a large Video Data Partition is splitted across several SL packets, and the last SL packet transporting the first Data Partition includes the separation marker and up to 7 subsequent bits of the second Data Partition in order to obtain byte alignment, the next SL packet starting on the next bit of the second Data Partition.
