Abstract :
High Efficiency Video Coding (HEVC) is the newest video coding standard, which is developed by the Joint Collaborative Team on Video Coding (JCT-VC) consisting of ITU-T Video Coding Experts Group (VCEG) and ISO/IEC Moving Picture Experts Group (MPEG). To improve the coding efficiency, HEVC adopts many new key techniques, such as coding tree unit, prediction unit, transform unit, multi-angle intra prediction, variable PU motion estimation, sample adaptive offset, and so on. Compared with its predecessor-H.264/AVC, HEVC is able to save about 50% bit rate while maintaining almost the same perceptual video quality. This paper aims to illustrate the key techniques of the HEVC standard and preview its extension in the near future.
