High efficiency coding and media delivery in heterogeneous environments (MPEG-H) is an integrated standard that resumes the original MPEG “one and trine” Systems-Video-Audio standards approach. In the wake of those standards, the 3 parts can be and are actually used independently, e.g. in video streaming applications. On the other hand, ATSC have adopted the full Systems-Video-Audio triad with extensions of their own.

MPEG-H has 15 parts, as follows

1. Part 1 – MPEG Media Transport (MMT) is the solution for the new world of broadcasting where delivery of content can take place over different channels each with different characteristics, e.g. one-way (traditional broadcasting) and two-way (the ever more pervasive broadband network). MMT assumes that the Internet Protocol is common to all channels.
2. Part 2 – High Efficiency Video Coding (HEVC) is the latest approved MPEG video coding standard supporting a range of functionalities: scalability, multiview, from 4:2:0 to 4:4:4, up to 16 bits, Wider Colour Gamut and High Dynamic Range and Screen Content Coding
3. Part 3 – 3D Audio is the latest approved audio coding standards supporting enhanced 3D audio experiences
4. Parts 4, 5 and 6 Reference software for MMT, HEVC and 3D Audio
5. Parts 7, 8, 9 Conformance testing for MMT, HEVC and 3D Audio
6. Part 10 – MPEG Media Transport FEC Codes specifies several Forward Error Correcting Codes for use by MMT.
7. Part 11 – MPEG Composition Information specifies an extension to HTML 5 for use with MMT
8. Part 12 – Image File Format specifies a file format for individual images and image sequences
9. Part 13 – MMT Implementation Guidelines collects useful guidelines for MMT use
10. Parts 14 – Conversion and coding practices for high-dynamic-range and wide-colour-gamut video and 15 – Signalling, backward compatibility and display adaptation for HDR/WCG video are technical reports to guide users in supporting HDR/WCC,
