MPEG-H explained

MPEG-H is a group of international standards under development by the ISO/IEC Moving Picture Experts Group (MPEG). It has various "parts" – each of which can be considered a separate standard. These include a media transport protocol standard, a video compression standard, an audio compression standard, a digital file format container standard, three reference software packages, three conformance testing standards, and related technologies and technical reports.^{[1] [2] [3] [4] [5]} The group of standards is formally known as ISO/IEC 23008 – High efficiency coding and media delivery in heterogeneous environments.^{[1] [2] [3] [4] [5]} Development of the standards began around 2010, and the first fully approved standard in the group was published in 2013.^[2] Most of the standards in the group have been revised or amended several times to add additional extended features since their first edition.

MPEG-H consists of the following parts:^{[3] [6]}

• Part 1: MPEG Media Transport (MMT) – a media streaming format similar to the Real-time Transport Protocol that is adaptable to different networks^{[1] [6] [7]}
• Part 2: High Efficiency Video Coding (HEVC, jointly developed with the ITU-T Video Coding Experts Group and also published as ITU-T H.265)^{[2] [8] [9]} – a video compression standard that doubles the data compression ratio compared to H.264/MPEG-4 AVC^{[6] [8] [9] [10]}
• Part 3: 3D Audio^[3] – an audio compression standard for 3D audio that can support many loudspeakers^[6]
• Part 4: MMT Reference and Conformance Software (not yet published)
• Part 5: Reference Software for High Efficiency Video Coding^[4] (also published as ITU-T H.265.2)^[11]
• Part 6: 3D Audio Reference Software
• Part 7: MMT Conformance (not yet published)
• Part 8: Conformance Specification for HEVC^[5] (also published as ITU-T H.265.1)^[12]
• Part 9: 3D Audio Conformance Testing
• Part 10: MPEG Media Transport Forward Error Correction Codes
• Part 11: MPEG Media Transport Composition Information
• Part 12: Image File Format – a.k.a. High Efficiency Image File Format (HEIF), based on the ISO base media file format
• Part 13: MPEG Media Transport Implementation Guidelines (a technical report rather than a standard)
• Part 14: Conversion and Coding Practices for HDR/WCG Y′CbCr Video with PQ Transfer Characteristics (a technical report also published as ITU-T H-series supplement 15)^[13]
• Part 15: Signalling, backward compatibility and display adaptation for HDR/WCG video (a technical report also published as ITU-T H-series supplement 18)^[14]
