- Recently a terminal having the multiple interfaces for communication may further support a high data throughput and more robust connectivity. MPEG Media Transport (MMT) was standardized as a digital container standard by Moving Picture Expert Group(MPEG) in March 2014 for next-generation broadcasting and communication services. MMT is to allow efficient transmission and processing of the video, audio and signaling information to support the new service such as Ultra High Definition TV (UHD TV), multi-screen service, and etc. In this paper, we design an MMT based Hybrid delivery system (MHD system) to provide seamless UHD TV service using satellite broadcasting link and broadband link. Our system uses two network interfaces, one is DVB-S2 for satellite broadcasting service and the other one is Ethernet for broadband IP data service, especially we use a broadband link for providing a high connection reliability when satellite link has a problem. And we design our system to support compatibility to the MPEG2-TS based legacy satellite broadcasting system for the MMT based new services.
