摘要
HEVC (High Efficiency Video Coding)是由JCT-VC (Joint Collaborative Team on Video Coding)开发的一种新的国际视频编码标准。本文对HEVC的运动矢量编码技术进行了综述。我们提出了三种用于HEVC的运动矢量预测器(MVP)的编码工具，包括时间矢量预测器的新位置、基于优先级的空间矢量预测器派生方法和时间矢量预测器派生方法。在高效随机访问、低复杂度随机访问、高效低延迟和低复杂度低延迟方面，这三种工具的组合可以分别实现平均1.3%、1.8%、1.2%和2.2%的比特率降低。
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.
