In this paper, we address the side information generation problem in Distributed Video Coding (DVC). To decode the current Wyner-Ziv frame, the DVC decoder usually generates side information by using motion compensated frame interpolation (MCFI) algorithms with neighboring decoded key frames. We survey some MCFI algorithms and side information generation methods based on MCFI. We also discuss our novel idea using edge information of decoded frames to generate more accurate interpolated frame. The experimental results show that it is reasonable to use edge information to improve side information at the decoder.
