Call for Proposals issued for screen content coding extensions to HEVC video coding standard
The ITU Video Coding Experts Group (VCEG) and the ISO/IEC Moving Picture Experts Group (MPEG) have issued a joint Call for Proposals for possible screen-content coding extensions to the new High Efficiency Video Coding (HEVC) standard approved in April 2013 as ITU-T H.265 | ISO/IEC 23008-2 (detailed in an ITU press release here).
The first version of HEVC targets the coding of 4:2:0 video and the standard is being extended to code 4:2:2 and 4:4:4 content via the ‘HEVC Range Extensions’ amendment currently under development. Other HEVC extension work already under development includes scalability extensions and 3D video coding extensions.
After evaluating initial evidence that significant improvements in coding efficiency can be achieved by further exploiting the characteristics of screen content with novel dedicated coding tools, the joint Call for Proposals has been issued to seek contributions to the investigation into the possible future standardization of such features in an additional extension project.
10 February 2014 is the registration deadline for proponents to declare their intent to participate, and 5 March 2014 is the deadline for coded test material to be submitted for subjective video quality testing of the proposals. 17 March 2014 is the deadline for the submission of the remaining proposal documents and associated data. The Call for Proposals provides a timeline of the procedures involved in the collection and analysis of proposals, as well as detailed descriptions of the required form and focus of proposals and the methodology to be used in evaluating them.
High Efficiency Video Coding (HEVC, Recommendation ITU-T H.265 | ISO/IEC 23008-2) is the video compression standard set to succeed the Primetime Emmy award winning Recommendation ITU-T H.264 | ISO/IEC 14496-10 ‘Advanced Video Coding’ (AVC).
The success of ITU-T H.264 | ISO/IEC 14496-10 AVC has been to such an extent that, today, almost all video we view, over any medium, is coded using it. With double the compression power, HEVC will provide the common platform for the next decade of innovation in the video sphere. It is expected to be phased in as new products and services appear and outgrow the limits of current network and display technology, underpinning advances in areas such as Ultra-high Definition TV, ‘4G’ mobile multimedia, and next-generation Blu-ray and gaming technology. It will also be deployed in many existing applications, wherever it is possible to deploy new decoders that can harness the power of the new standard to improve video quality and ease the burden of sending and storing video content.
