HEVC Overview

High Efficiency Video Coding Standard


ITU-T H.265 | MPEG-H - Part 2 (ISO/IEC 23008-2)

H.265/HEVC is a widely deployed standardized video compression technology.  It has been developed by the Joint Collaborative Team on Video Coding (JCT-VC) of the ITU-T Visual Coding Experts Group (VCEG) and the ISO/IEC Moving Pictures Experts Group (MPEG). The Joint Collaborative Team on 3D Video Coding Extension Development (JCT-3V) was established to work on multiview and 3D video coding extensions of HEVC.

The work on H.265/HEVC was split into the following overlapping phases.

  • Phase 1: First version of H.265/HEVC:
    Specification of the Main, Main 10, and Main Still Picture profiles,
    April 2010 – April 2013.
  • Phase 2: Format Range Extension (RExt):
    Specification of the Format Range Extension profiles,
    July 2012 – October 2014.
  • Phase 3: Scalability Extension (SHVC):
    Specification of the Scalable Main and Scalable Main 10 profiles,
    October 2012 – October 2014.
  • Phase 4: Multiview Extension (MV-HEVC):
    Specification of the Multiview Main profile,
    July 2012 – October 2014.
  • Phase 5: 3D Extension (3D-HEVC):
    Specification of the 3D Main profile,
    July 2012 – February 2015.
  • Phase 6: Screen Content Coding Extension (SCC):
    Ongoing, expected to be finalized in February 2016.

NOTE — More information on H.265/HEVC and the different extensions can be found on the HEVC support site.

Contributions of the Video Communication and Applications Department

The Video Coding Technologies Group contributed several essential coding tools and technologies to the H.265/HEVC standard, as listed below. Some of the contributions were developed in cooperation with the Multimedia Communication Group, the Video Coding Systems Group and the former 3D Coding Group.

In phase 1 (first version of H.265/HEVC) we contributed:

In phase 2 (RExt) we contributed:

In phase 3 (SHVC) we proposed:

  • Scalable video coding extension of HEVC, using block-level coding tools and multi-loop decoding

In phase 4 (MV-HEVC) we contributed:

In phase 5 (3D-HEVC) we contributed:

Administrative Support

The The Video Coding Systems and Video Coding Technologies Groups have been involved in the administration of the JCT-VC and JCT-3V standardization in various ways:
