Research on Key Algorithm of a New Generation Video Coding Standard HEVC

The video coding standard of a new generation, high efficiency video coding ( HEVC ), is a video coding standard of JCT-VT under planning, mainly orienting toward high definition television （HDTV）and video coding system. From the start of the basic structure of HEVC, this paper not only introduces comprehensively the key HEVC technologies in intra-frame and inter-frame predictive estimation, orthogonal transformation, filter compensation and entropy coding but also points out the hot issues and the latest research direction.
