s. The group of standards is formally known as ISO/IEC 23008 – ''High efficiency coding and media delivery in heterogeneous environments''. Development of the standards began around 2010, and the first fully approved standard in the group was published in 2013. 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: * Part 1: '' MPEG Media Transport'' (MMT) – a media streaming format similar to the Real-time Transport Protocol that is adaptable to different networks * Part 2: '' High Efficiency Video Coding'' (HEVC, jointly developed with the
