Abstract :
High Efficiency Video Coding (HEVC) is a new international video coding standard that has been developed by the Joint Collaborative Team on Video Coding (JCT-VC). In this paper, an overview of the motion vector coding techniques for HEVC is presented. Our three proposed coding tools for the motion vector predictor (MVP) in the Inter, Skip and Merge modes of HEVC are also presented, which includes a new location of the temporal MVP, a priority-based derivation method of spatial MVPs, and a derivation method of temporal MVPs. A combination of these three tools can achieve on average 1.3%, 1.8%, 1.2% and 2.2% bit rate reductions for high efficiency random access, low complexity random access, high efficiency low delay, and low complexity low delay, respectively.
