The ITU-T’s Study Group 16 has agreed first-stage approval (consent) of H.265 or ISO/IEC 23008-2, also known as ‘High Efficiency Video Coding’ (HEVC). The new video codec uses about half the bit rate of its predecessor, ITU-T H.264 / MPEG-4 Part 10 and is suitable for use in a range of applications, from mobile devices to Ultra-High Definition TV.
The specification was developed by the ITU Video Coding Experts Group (VCEG) and the ISO/IEC Moving Picture Experts Group (MPEG). 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.
Dr Hamadoun I. Touré, Secretary-General, ITU: “ITU-T H.264 underpinned rapid progression and expansion of the video ecosystem, with many adopting it to replace their own proprietary compression codecs. The industry continues to look to ITU and its partners as the global benchmark for video compression, and I have no doubt that this new standard will be as effective as its predecessor in enabling the next wave of innovation in this fast-paced industry.”
Companies including ATEME, Broadcom, Cyberlink, Ericsson, Fraunhofer HHI, Mitsubishi, NHK, NTT DOCOMO and Qualcomm have already showcased implementations of HEVC. The new standard includes a ‘Main’ profile that supports 8-bit 4:2:0 video, a ‘Main 10’ profile with 10-bit support, and a ‘Main Still Picture’ profile for still image coding that employs the same coding tools as a video ‘intra’ picture.
