Abstract: An apparatus and method for transmitting MPEG-4 data synchronized to MPEG-2 data is disclosed. The apparatus for transmitting MPEG-4 data synchronized to MPEG-2 data includes: an object separation unit for extracting MPEG-4 object data from MP4 data, separating meta information from the object data, and generating program information and synchronization information; a conversion unit for converting the MPEG-4 object data to MPEG-4 packets of which data structure is the same as that of MPEG-2 data, based on the program information and synchronization information; and a multiplexing unit for multiplexing the MPEG-4 packets with the MPEG-2 data.
