MPEG media transport (MMT), specified as ISO/IEC 23008-1 (MPEG-H Part 1), is a digital container standard developed by Moving Picture Experts Group (MPEG) that supports High Efficiency Video Coding (HEVC) video. MMT was designed to transfer data using the all-Internet Protocol (All-IP) network. In April 2013 a list of requirements was released for MMT and the general requirements stated that MMT must have clear advantages when compared to existing container formats and that it must have low computational demands. Also in April 2013 a list of use cases for MMT was released which included the need for it to support Ultra HD video content, 3D video content, interactive content, user-generated content, applications that support multi-device presentation, subtitles, picture-in-picture video, and multiple audio tracks. MPEG has estimated that the first edition of MMT will reach Final Draft International Standard (FDIS) in November 2013. On May 30, 2013, NHK started showing test equipment based on MMT at the NHK Science & Technology Research Laboratories Open House 2013. Schedule The timescale for the completion of the first version of the MMT standard in the MPEG standardization process:October 2010: Call for ProposalsMarch 2011: Working DraftJuly 2012: Committee DraftJanuary 2013: 2nd Committee DraftApril 2013: Draft International StandardNovember 2013: Final Draft International StandardMay 2014: International Standard published Highlights MPEG MMT succeeds MPEG-2 TS as the media transport solution for broadcasting and IP network content distribution, with the aim of serving new applications like UHDTV, second screen,..., etc., with full support of HTML5 and simplification of packetization and synchronization with a pure IP based transport. It has the following technology innovations:Convergence of IP transport and HTML 5 presentationMultiplexing of various streaming components from different sourcesSimplification of TS stack and easy conversion between storage file format and streaming formatSupport multiple devices and hybrid deliveryAdvanced QoS/QoE engineering features Solutions and demos SKT MMT based True Realtime (TR) video streaming solution (Oct' 2014)SK Telecom (The leading mobile operator in Korea) and Samsung have developed and tested their True Real Time Mobile Streaming system based on the emerging MPEG MMT standard over SKT's commercial LTE network with Btv video streaming platform. The results showed latency reduction of 80%, which would significantly improve the user experience of live content streaming. Current mobile video streaming technologies often suffer up to 15 seconds of latency, but its implementation of MMT has reduced that to 3 seconds. SK Telecom said they will put more efforts to strengthen their mobile network service quality by developing innovative and advanced technologies with the aim of having it commercially available next year.
