Statistical analysis of intra prediction in HEVC video encoder

Abstract

High Efficiency Video Coding (HEVC) standard represents the newest video coding standard generation for both ITU-T Video Coding Experts Group and the ISO/IEC Moving Picture Experts Group. The new standard reduces bitrates by 50% compared to the existing standards using Advanced Video Coding (AVC) for equal video quality. This paper provides an overview of the technical features and characteristics of the new HEVC standard. A detailed statistical analysis of intra prediction unit showed that the RDO process represent the most time consuming module. Concerning intra prediction mode selection, the frequently chosen modes were 0, 1, 26, and 10. Then, the optimal mode represents on average 87% to belong to the most probable mode list MPM.
