HEVC, which stands for High Efficiency Video Coding, is a video compression standard that is also known as H.265. It is the successor to the H.264 standard and was officially ratified on April 13, 2013 by the JCT-VC (Joint Collaborative Team on Video Coding).
The JCT-VC is comprised of members of both the Motion Pictures Experts Group and the Video Coding Experts Group who came together specifically to develop the HEVC standard. Theoretically, HEVC/H.265 offers double the compression ratio of H.264 (the video uses one-half the amount of data), without a reduction in video quality.
