Recommendation ITU-T H.264.1: Conformance specification for H.264 advanced video coding

The conformance bitstreams identified in Rec. ITU-T H.264.1 are used for the tests specified in this Recommendation. The tests allow verifying whether bitstreams and decoders meet the normative requirements specified in Rec. ITU-T H.264 | ISO/IEC 14496-10:
  • An encoder can claim conformance to Rec. ITU-T H.264 | ISO/IEC 14496-10 if the bitstreams that it generates are conforming bitstreams.
  • A decoder can claim conformance to a specified profile and level of Rec. ITU-T H.264 if it can properly decode all bitstreams obeying constraints specified in Rec. ITU-T H.264 | ISO/IEC 14496-10.
Rec. ITU-T H.264 | ISO/IEC 14496-10 represents an evolution of earlier video coding standards (ITU-T H.261, ITU-T H.262, and ITU-T H.263) and it was developed in response to the growing need for higher compression of moving pictures for various applications such as videoconferencing, digital storage media, television broadcasting, Internet streaming, and communication. 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 codec 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.
