摘　　要：Distributed source coding （DSC） and Distributed video coding （DVC） have aroused high research interest due to their property of low-complexity encoding. This paper presents a residual DVC based on Low quality reference （LQR） hash compressed by 0-motion H.264/AVC. SW-SPIHT is applied to the residual between Wyner-Ziv frame and the decoded LQR hash, which exploits the temporal and spatial correlations so improves the coding efficiency. At the decoder, the decoded LQR is used for more accurate motion estimation and better side information. And a refinement reconstruction with side information is proposed for better SPIHT decoding. The experimental results indicate the proposed scheme achieves better rate-distortion performance than current literatures under the constraint of similar encoding complexity.
