MPEGメディア転送プロトコル[1] (MPEG media transport, MMT), specified as ISO/IEC 23008-1 (MPEG-H Part 1), is a digital container standard under development by Moving Picture Experts Group (MPEG) that will support High Efficiency Video Coding (HEVC) video.[2][3] MMT was developed by the Electronics and Telecommunications Research Institute, Kyung Hee University, and Samsung Electronics.[4] MMT was designed to transfer data using the all-Internet Protocol (All-IP) network.[4]
History[編集]
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.[5][6] 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.[5][7] MPEG has estimated that the first edition of MMT will reach Final Draft International Standard (FDIS) in November 2013.[8][9]
On May 30, 2013, NHK started showing test equipment based on MMT at the NHK Science & Technology Research Laboratories Open House 2013.[10]
Schedule[編集]
The timescale for the completion of the first version of the MMT standard in the MPEG standardization process:[9]
- October 2010: Call for Proposals
- March 2011: Working Draft
- July 2012: Committee Draft
- January 2013: 2nd Committee Draft[11][12]
- April 2013: Draft International Standard[13]
- November 2013: Final Draft International Standard
