摘要： Provided are a method and apparatus for enabling a main stream to refer to an elementary stream existing in another simple aggregation format (SAF) session by using a global ID during provision of a light application scene representation (LASeR) service, and a LASeR service providing apparatus. In order for a main stream to refer to an elementary stream included in an SAF session different from an SAF session in which the main stream is included without a change of existing LASeR and SAF stream structures, the main stream for a LASeR service uses a global stream ID of the elementary stream as a reference value. Accordingly, the elementary stream included in the SAF session different from the SAF session of the main stream can be effectively referred to without need to create a separate apparatus or change an existing apparatus even when a global ID included in a LASeR scene description is used as in the conventional art.

摘要： Provided is a Simple Aggregation Format (SAF) synchronization packet structure including an SAF synchronization packet header and an SAF synchronization packet payload and multiplexing diverse element streams. The header includes a field for providing time information needed when objects transmitted as a SAF synchronization layer packet payload compose a scene in a decoder; and the payload includes a field for providing information on the type of an access unit and a field for providing identification information of an elementary stream where the access unit belongs. 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.

摘要： Provided are a method and apparatus for displaying lightweight applications scene representation (LASeR) content. A LASeR markup language (ML) that is based on a LASeR binary stream or a LASeR extensible markup language (XML) is parsed so as to generate a LASeR document object model (DOM). A LASeR application program interface (API) is used to generate a LASeR DOM object tree. A LASeR player accesses the LASeR DOM to display LASeR DOM scene information.
