ITU-T H.265 now available for download

The highly-anticipated video coding standard, ITU-T H.265 ‘High Efficiency Video Coding’ (HEVC), is now available free of charge on the ITU website here.

Recommendation ITU-T H.265 is a technically-aligned twin text with International Standard ISO/IEC 23008-2. The standard was developed within the Joint Collaborative Team on Video Coding (JCT-VC), a mechanism underscoring the longstanding collaboration of the ITU Video Coding Experts Group (VCEG) and the ISO/IEC Moving Picture Experts Group (MPEG).

ITU-T H.265 will need only half the bit rate of its predecessor, ITU-T H.264 | MPEG-4 Part 10 ‘Advanced Video Coding’ (AVC), which remains the most deployed video compression standard worldwide. The new standard is designed to take account of advancing screen resolutions and is expected to be phased in as high-end products and services outgrow the limits of current network and display technology.

The development of ITU-T H.265 was led by ITU-T Study Group 16 (Multimedia) and the standard was approved by ITU members on 13 April 2013 (detailed in a press release here).

April also saw the approval of the latest edition of HEVC’s predecessor, ITU-T H.264. Ten years old this year, ITU-T H.264 is now in its eighth edition and is available free of charge on the ITU website here. The latest edition contains an additional profile for multiview video coding with depth information (the Multiview and Depth profile) as well as additional colourimetry identifiers and improvements to supplemental enhancement information (SEI) messages.
