Implementing a device or software application that uses HEVC may require a license from HEVC patent holders. HEVC contains technologies covered by patents owned by the organizations that participated in the JCT-VC. In October 2017, the standard was recognized by a Primetime Emmy Engineering AwardĪs having had a material effect on the technology of television. Extensions for 3D video (3D-HEVC) were completed in early 2015, and extensions for screen content coding (SCC) were completed in early 2016 and published in early 2017, covering video containing rendered graphics, text, or animation as well as (or instead of) camera-captured video scenes. The second version, with multiview extensions (MV-HEVC), range extensions (RExt), and scalability extensions (SHVC), was completed and approved in 2014 and published in early 2015. The first version of the HEVC standard was ratified in January 2013 and published in June 2013. The ISO/IEC group refers to it as MPEG-H Part 2 and the ITU-T as H.265. HEVC was standardized by the Joint Collaborative Team on Video Coding (JCT-VC), a collaboration between the ISO/ IEC MPEG and ITU-T Study Group 16 VCEG.

Effective use of these improvements requires much more signal processing capability for compressing the video, but has less impact on the amount of computation needed for decompression. The primary changes for HEVC include the expansion of the pattern comparison and difference-coding areas from 16×16 pixel to sizes up to 64×64, improved variable-block-size segmentation, improved 'intra' prediction within the same picture, improved motion vector prediction and motion region merging, improved motion compensation filtering, and an additional filtering step called sample-adaptive offset filtering. These redundant areas are then replaced with a short description instead of the original pixels. Both work by comparing different parts of a frame of video to find areas that are redundant, both within a single frame and between consecutive frames. In most ways, HEVC is an extension of the concepts in H.264/MPEG-4 AVC. The High Efficiency Image Format (HEIF) is based on HEVC. While AVC uses the integer discrete cosine transform (DCT) with 4×4 and 8×8 block sizes, HEVC uses both integer DCT and discrete sine transform (DST) with varied block sizes between 4×4 and 32×32. It supports resolutions up to 8192×4320, including 8K UHD, and unlike the primarily 8-bit AVC, HEVC's higher fidelity Main 10 profile has been incorporated into nearly all supporting hardware. In comparison to AVC, HEVC offers from 25% to 50% better data compression at the same level of video quality, or substantially improved video quality at the same bit rate. High Efficiency Video Coding ( HEVC), also known as H.265 and MPEG-H Part 2, is a video compression standard designed as part of the MPEG-H project as a successor to the widely used Advanced Video Coding (AVC, H.264, or MPEG-4 Part 10).

It finds the applications in interactive or serial storage on optical and magnetic storage devices, DVDs (Digital Video Disk). The new H.264/AVC & Enhanced version H.265 standard is designed to provide a technical solution, the H.265 is the latest video compression technique in which 50% of bit rate is saved more than H.264 and broad range of applications, including broadcast over cable, satellite, cable modem, and terrestrial. The time has arrived to see what has been accomplished. The work has been stimulating, intense, dynamic, and all-consuming for those of us most deeply involved in its design.

Work on the emerging ' Advanced Video Coding ' (AVC) standard now known as ITU-T(International Telecommunication Union) Recommendation H.264 and as ISO 14496(International Organization For Standards) (MPEG-4) Part 10 has dominated the video coding standardization community. MPEG1 (Motion Picture Expert Group), MPEG2, MPEG4, H.261, H.263, H.264 are the ancestors of H.265. Only the residual information is transmitted using the technique called as block based motion estimation and motion compensation. Video compression algorithms take the advantage of this fact. The successive images are highly correlated with each other.

Video is the sequence of images played with respect to time.
