H.265 HD HEVC Video Format Is Ratified
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. 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.
When will we see the new codec taking shape on the web? That's harder to say, but it's great that companies are already thinking about this. Even a 5%-15% savings in data rate transmission could save gobs of bandwidth globally given just how many billions of hours are invested on sites like YouTube, Vimeo, Hulu, Netflix, etc.
