Review of Video Encoding Standard: HEVC / H.265
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.
Some of the major Technique contributors to the higher compression performance of HEVC are the introduction of quad tree structure, larger block structures with flexible mechanisms of
sub-partitioning , improved techniques to support parallel encoding/decoding, more directional intra prediction modes, support for several integer transforms with square as well as non square transforms, merging of prediction blocks for improved motion information encoding, and extensive In-loop processing on reconstructed pictures.
The primary goal of the new codec is 50 percent better compression efficiency than H.264 and support for resolutions up to 8192 x 4320. It unlocks future business notably suitable for resolutions up to Ultra High Definition (UHD) video coding in the future.
