Abstract
Provided is a Simple Aggregation Format (SAF) synchronization packet structure including a SAF synchronization packet header and a SAF synchronization packet payload and multiplexing diverse element streams which include a scene description elementary stream. The SAF synchronization packet header includes time information related to an access unit included in the SAF synchronization packet payload, and the SAF synchronization packet payload includes header information on the access unit and payload information indicating the access unit. Since the present invention can multiplex diverse elementary streams effectively and simply into one data stream, synchronized data transmission is possible. Since the present invention accommodates a synchronization layer packet of the MPEG-4 system, it can be easily integrated with the MPEG-4 system and utilize the advantage of the MPEG-4 synchronization layer packet such as the concept of an access unit or a degradation priority.
