Successor to award-winning standard to unleash new innovation

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

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

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’

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.
