ITU members approved H.265 video compression standard, known informally as ‘High Efficiency Video Coding’ (HEVC), and considered to be twice more effective than the widely adopted now H.264. The approval is believed to pave the way for 4K video devices, HDR features in video and more.
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) 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.
