MPEG media transport
|Type of format||Digital container format|
|Container for||Audio, video, data|
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.
The timescale for the completion of the first version of the MMT standard in the MPEG standardization process:
- October 2010: Call for Proposals
- March 2011: Working Draft
- July 2012: Committee Draft
- January 2013: 2nd Committee Draft
- April 2013: Draft International Standard
- November 2013: Final Draft International Standard
- May 2014: International Standard published
MMT Technology 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 UHD, 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 presentation
- Multiplexing of various streaming components from different sources
- Simplification of TS stack and easy conversion between storage file format and streaming format
- Support multiple devices and hybrid delivery
- Advanced QoS/QoE engineering features
MMT Technology Based 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.
- Technicolor-Sinclair Demo (Oct' 2014)
Sinclair Broadcast Group and Technicolor delivered successfully ATSC 3.0 4K UHD testbed platform. The Technicolor platform, based on open audio, video and transport standards including Scalable HEVC (SHVC), MPEG-H audio and MPEG-MMT transport, has been integrated into Sinclair's experimental OFDM transmission system in Baltimore, Maryland. The impact of this deployment is that broadcasters will be able to deliver the highest quality content, inclusive of 4K UHD broadcast in a simultaneous transmission to consumers both at home and on-the-go.
- NHK MMT UHD system demo (May, 2014)
In Japan, Super Hi-Vision test services are planned to begin in 2016, and commercial services are planned to begin in 2020. NHK has studied MPEG Media Transport (MMT) as the transport protocol for the next generation of broadcasting systems since it enables hybrid delivery using broadcasting and broadband networks. They have demonstrated MMT-based 8K Super Hi-Vision Broadcasting at their open house exhibition.
