摘要：

The RD performance of distributed video coding (DVC) is lower than conventional video coding. This article analyzes the reason of that, finds during the decoding process DVC does not make full use of the set of side information in the distributed framework. Then paper proposes a way to improve the prediction accuracy, during the process of generating predictive side information, makes full use of the distributed structural characteristics, improves the RD performance of DVC by using bidirectional motion estimation and the weighted average methods.
