With the development of broadcasting technologies, broadcasting systems providing an audio/video service and a limited data service using the MPEG2 transport stream were developed by MPEG in the 1990s. The MPEG2 transport stream efficiently provides a real time audio/video service and synchronization information of the audio/video. However, utilization of the MPEG2 transport stream is limited due to a fixed frame size of 188 bites, restricted multiplexing, and complex data broadcasting. Thus MPEG started to develop a next-generation transport system in 2008.
The next generation transport system is called MMT, and may provide a function for an audio/video multimedia service, a data broadcasting service, and a multiscreen service through a broadcasting network or an Internet Protocol (IP) network. Further, MMT is suggested to be used in a broadcasting network, an IP network, or a predetermined transmission network. Accordingly, there is a need for MMT application to a digital broadcasting system such as a Digital Video Broadcasting (DVB) system.
