    • 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.
    • 提供了包括SAF同步分组报头和SAF同步分组有效载荷的简单聚合格式(SAF)同步分组结构,并且复用包括场景描述基本流的各种元素流。 SAF同步分组报头包括与包含在SAF同步分组有效载荷中的接入单元相关的时间信息,SAF同步分组有效负载包括关于接入单元的报头信息和指示接入单元的有效载荷信息。 由于本发明可以将不同的基本流有效且简单地复用到一个数据流中,所以可以进行同步的数据传输。 由于本发明容纳了MPEG-4系统的同步层分组,所以可以容易地与MPEG-4系统集成,并利用MPEG-4同步层分组的优点,诸如接入单元或降级的概念 优先。
