Distributed Video Coding (DVC) in transform domains could yield significant coding gains over the pixel domain. While employing different coding modes in DVC, it is still difficult to fully compress the source data without increasing the complexity at the encoder side. In this paper, we first propose a particular Run-Length-Coding (RLC) coding mode to efficiently compress the continuous zero symbols to improve coding efficiency. Then a hybrid codec scheme for WZ frames by combining Turbo and RLC coding is introduced, where the mode decision is determined at the decoder side to maintain the encoder-side complexity simplicity. Simulation results show that the proposed method gains up to 1 dB when compared with the Transform domain Wyner-Ziv Coding (TDWZ).
