Rate-distortion (RD) performance of distributed video coding (DVC) is considerably less than that of conventional predictive video coding. In order to reduce the performance gap, many methods and techniques have been proposed to improve the coding efficiency of DVC with increased system complexity, especially techniques employed at the encoder. For example, encoder mode decisions, optimal quantization and hash methods no doubt increase the complexity of the encoder. However, low complexity encoder is a widely desired feature of DVC. In order to improve the coding efficiency while maintaining low complexity encoder, this paper focuses on distributed residual video coding (DRVC) architecture and proposes a simple encoder scheme. The main contributions of this paper are as follows: 1) propose a bit-plane block-based method combined with bit-plane re-arrangement to improve the dependency between source and side information (SI), while reducing the amount of data to be channel encoded; 2) present a simple iterative dead-zone quantizer with three levels, in order to adjust quantization from coarse to fine. The simulation results show that the proposed scheme outperforms the DISCOVER scheme for low-to-medium motion video sequences in terms of RD performance, while also maintaining a low complexity encoder at the same time.
