High Efficiency Video Coding
HEVC / H.265

The new standard for video coding released by ISO MPEG and ITU-T VCEG.

High Efficiency Video Coding (HEVC) is a new Standard for video compression developed by the ISO and ITU-T. The Moving Picture Experts Group (MPEG) and Video Coding Experts Group (VCEG) set up a Joint Collaborative Team on Video Coding (JCT-VC) to create the new standard. HEVC is a joint publication of ISO/IEC and ITU-T, formally known as ISO/IEC 23008-2 and ITU-T Recommendation H.265. The new HEVC standard was first published in January 2013.

How Good is HEVC?

Using the new High Efficiency Video Coding (HEVC) / H.265 standard, video can be compressed into a smaller size or bitrate.

The HEVC Test Model
The Test Model defines two broad categories of video coding tools, for (a) High Efficiency and (b) Low Complexity applications:

The Joint Collaborative Team
From the ITU website: “The Joint Collaborative Team on Video Coding is a group of video coding experts from ITU-T Study Group 16 (VCEG) and ISO/IEC JTC 1/SC 29/WG 11 (MPEG) created to develop a new generation video coding standard that will further reduce by 50% the data rate needed for high quality video coding, as compared to the current state-of-the-art AVC standard (ITU-T Rec. H.264 | ISO/IEC 14496-10). This new coding standardization initiative is being referred to as High Efficiency Video Coding (HEVC).”
