Recommendation ITU-T H.265 | International Standard ISO/IEC 23008-2 represents an evolution of the existing video coding Recommendations (ITU-T H.261, ITU-T H.262, ITU-T H.263 and ITU-T H.264) and was developed in response to the growing need for higher compression of moving pictures for various applications such as Internet streaming, communication, videoconferencing, digital storage media and television broadcasting. It is also designed to enable the use of the coded video representation in a flexible manner for a wide variety of network environments. The use of this Recommendation | International Standard allows motion video to be manipulated as a form of computer data and to be stored on various storage media, transmitted and received over existing and future networks and distributed on existing and future broadcasting channels.
This revision adds the specification of a new profile, namely the Multiview Main 10 profile, and the support of 12 new SEI messages through referencing to Rec. ITU-T H.274 | ISO/IEC 230027, namely the 1) SEI processing order, 2) processing order nesting, 3) encoder optimization information, 4) source picture timing information, 5) modality information, 6) digitally signed content initialization, 7) digitally signed content selection, 8) digitally signed content verification, 9) generative face video, 10) generative enhancement face video, 11) AI usage restrictions request, and 12) packed regions information SEI messages. This revision also includes some updates to the interface text for support of the two neural-network post-filter (NNPF) SEI messages, an extension to the film grain characteristics SEI message, and corrections to various minor defects in the prior content of the Specification.
This Recommendation | International Standard was developed jointly with ISO/IEC JTC 1/SC 29 and corresponds in a technically aligned manner to ISO/IEC 23008-2.
