Proposed is a novel side information refinement technique for Wyner-Ziv video frames in distributed video coding using sequential motion compensation with luminance and chrominance information for a given bit plane to update the side information for the next bit plane. Simulation results show that over 3 dB PSNR gain can be obtained with the proposed algorithm over the best available pixel domain Wyner Ziv codec from the literature [Natario et al.] at the same bit rate.
