Apparatus and method for transmitting multimedia data in a broadcast system

摘要

The present invention relates to an apparatus and method for transmitting multimedia data in a broadcast system. According to the present invention, a method for constructing a payload for a multimedia frame to be transmitted via a heterogeneous network, in a broadcast system that supports an Internet protocol-based multimedia service, comprises the following processes: dividing the data so as to transmit data of at least one media type and constructing a data region based on each datum of the divided data; constructing a header region including information on the state of the data contained in the data region and/or information on the data region; and combining the data region and the header region to construct a payload for the frame.
