Recently, distributed video coding (DVC) has attracted much more attention with advances in low-complexity encoder and flexible architecture, which could be effectively applied in mobile video communication and video surveillance network. But the gap with the conventional video codecs is still large. One of the key factors is the quality of side information as it directly affects the system's rate distortion performance. In this paper, existing algorithms of side information generation in multi-view DVC system are compared, and a new scheme based on feedback channel and fusion will be proposed. Experimental results represent that the proposed scheme can provide better rate distortion performance with the existing ones.
