HEVC video coding standard is the next generation of H.264 coding standard, which is able to achieve twice coding efficiency compared with H.264/AVC High Profile. This paper analyzes the key features of HEVC standard based on HEVC reference software HM12.0. Experiments cover different resolutions ranging from 240p to 1600p. The most complex parts of HEVC decoder are intra prediction, loop filter and inverse transform when video sequences are coded with all-intra configuration. When video sequences are coded in random-access configuration, HEVC decoding process is occupied by motion compensation, which takes nearly half of the decoding time. Experiment results indicate that HEVC standard can achieve 50% average bit-rate saving compared with H.264.
