Abstract
The next generation video coding standard, High Efficiency Video Coding (HEVC), is under development by the Joint Collaborative Team on Video Coding (JCT-VC) of the ITU-T VCEG and the ISO/IEC MPEG. As the first version of single-layer HEVC standard comes close to completion, there is a great interest to extend the standard with scalable capabilities. In this paper, an inter-layer Motion Field Mapping (MFM) algorithm is proposed for the scalable extension of HEVC to generate the motion field of inter-layer reference pictures, such that the correlation between the motion vectors (MVs) of base-layer and enhancement-layer can be exploited. Moreover, as the proposed method does not change any block-level operation, the existing single-layer encoder and decoder logic of HEVC can be directly applied without modification of motion vector prediction for the enhancement-layer. The experimental results show the effectiveness of the proposed MFM method in improving the performance of enhancement-layer motion prediction in scalable HEVC.
