New MPEG Transport Standard for Next Generation Hybrid Broadcasting System With IP

MPEG-2 transport system (TS) and ISO base media file format (ISOBFF) standards developed by MPEG have been widely used by various industries and applications including digital broadcasting systems. Recently MPEG has developed a new standard, MPEG Media Transport or MMT, for next generation broadcasting system considering the emerging convergence of digital broadcasting network and the Internet. MMT assumes HTML5 and Internet protocol (IP) as deployment environment and inherits major features of MPEG-2 TS while simplifying unnecessary complicated features in IP environments. It also considers hybrid delivery of multi-screen services. MMT defines an application layer protocol enabling packetization of opaque objects or files without considering the structure of data and media processing unit (MPU) format specific packetization. Synchronization technology of MMT providing flexible synchronization of multimedia components delivered through hybrid environment over multiple devices is built on top of HTML5.
