ITU approves High Efficiency Video Coding (HEVC) standard H.265

GENEVA, SWITZERLAND — High Efficiency Video Coding (HEVC), the new video compression standard designed to use half the data of it’s H.264 predecessor, received the nod of approval from the ITU-T‘s Study Group 16 today. (What is HEVC?).

The first-stage approval (consent) of the Ultra HD video encoding format will ease the burden on global networks, since an estimated 50% of all bandwidth comes from video data. Currently, the popular H.264 codec — predecessor to HEVC — accounts for over 80% of all video on the Internet, and it should be no surprise that HEVC will gain widespread adoption just as soon as content providers update their encoding platforms to support high-end consumer products. HEVC will pave the way video is transmitted to a variety of devices, including mobile devices and Ultra HDTV’s.

Dr. Hamadoun I. Touré, Secretary-General of the ITU said:

“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.”

According to the ITU, HEVC (formally known as “Recommendation ITU-T H.265 or ISO/IEC 23008-2″) will provide a flexible, reliable, and robust solution to support the next decade of video. The standard accounts for advances in screen resolution, thereby making the codec “future-proof.” A variety of companies have already demonstrated use of HEVC, including ATEME, Broadcom, Cyberlink, Ericsson, Fraunhofer HHI, Mitsubishi and NHK.

The ITU/ISO/IEC Joint Collaborative Team on Video Coding (JCT-VC) will continue work on a range of extensions to HEVC, including support for 12-bit video as well as 4:2:2 and 4:4:4 chroma formats. The group will also work within the Joint Collaborative Team on 3D-Video to make stereoscopic and 3D video coding a reality.

Geneva, 25 January 2013 – A new video coding standard building on the PrimeTime Emmy award winning ITU-T H.264 / MPEG-4 AVC was agreed by ITU members today.

The new codec will considerably ease the burden on global networks where, by some estimates, video accounts for more than half of bandwidth use. The new standard, known informally as ‘High Efficiency Video Coding’ (HEVC) will need only half the bit rate of its predecessor,ITU-T H.264 / MPEG-4 Part 10 ‘Advanced Video Coding’ (AVC), which currently accounts for over 80 per cent of all web video. HEVC will unleash a new phase of innovation in video production spanning the whole ICT spectrum, from mobile devices through to Ultra-High Definition TV.

ITU-T’s Study Group 16 has agreed first-stage approval (consent) of the much-anticipated standard known formally as Recommendation ITU-T H.265 or ISO/IEC 23008-2. It is the product of collaboration between the ITU Video Coding Experts Group (VCEG) and the ISO/IEC Moving Picture Experts Group (MPEG).

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.”

ITU-T H.264 / MPEG-4 AVC is deployed in products and services from companies including Adobe, Apple, BBC, BT, France Telecom, Intel, Microsoft, Motorola, Nokia, Polycom, Samsung, Sony, Tandberg, Toshiba and others to deliver high definition video images over broadcast television, cable TV, a variety of direct-broadcast satellite-based television services, Blu-Ray disc formats, mobile phones, videoconferencing tools, digital storage media, and Internet Protocol television (IPTV). It remains the most deployed global video compression standard.

ITU-T H.265 / ISO/IEC 23008-2 HEVC will provide a flexible, reliable and robust solution, future-proofed to support the next decade of video. 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.

Companies including ATEME, Broadcom, Cyberlink, Ericsson, Fraunhofer HHI, Mitsubishi and NHK 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.

The ITU/ISO/IEC Joint Collaborative Team on Video Coding (JCT-VC) (formerly JVT) will continue work on a range of extensions to HEVC, including support for 12-bit video as well as 4:2:2 and 4:4:4 chroma formats. Another important element of this work will be the progression of HEVC towards scalable video coding. The three bodies will also work within the Joint Collaborative Team on 3D-Video (JCT-3V) on the extension of HEVC towards stereoscopic and 3D video coding.
