Abstract:
1. An apparatus for generating and transmitting moving picture expert group-4 (MPEG-4) data synchronized with a MPEG-2 data, comprising: object separating and information generating means for extracting MPEG-4 object data and meta information related to the MPEG-4 object data from mp4 data which is a storage type of the MPEG-4 data, for analyzing the meta information and for generating program information and synchronization information, wherein said synchronization information is generated by using a composition time stamp (CTS) which is meta information extracted in said object separating means, and a flexible multiplex (FlexMux) packet length information which is a FlexMux packet header information; packetizing means for converting the MPEG-4 object data to a MPEG-4 transport stream (TS) packet having a data format of MPEG-2 data by using the meta information, the program information and the synchronization information in order to synchronize the MPEG-4 object data with the MPEG-2 data; and program multiplexing means for multiplexing the MPEG-4 TS packet and the MPEG-2 data and for generating and outputting a transport stream packet.
