Abstract

In the distributed video coding system, sideinformation takes an important role in reconstructing the Wyner-Ziv frames. To generate good sideinformation, we propose a new interpolation strategy based on motion estimation and motion compensation which exploits the video temporal redundancy. Besides, we propose a new framework based on the above strategy. In this framework, multi-estimation mode and a new refinement to side-information are added. Experimental results show that the PSNR of the new framework is improved notably compared with normal DVC system.
