Abstract

A novel concept of channel division to improve the performance of distributed video coding is proposed in this work. At the decoder, the proposed algorithm partitions each side information frame into multiple regions with different expected distortions. It is shown that the partitioning is equivalent to the division of the virtual noisy channel from the encoder to the decoder into multiple channels. Then, the proposed algorithm analyzes the noise characteristics of those multiple channels, and allocates a limited bit budget to those channels adaptively to improve the rate-distortion performance. Simulation results demonstrate that the proposed algorithm provides up to 5 dB better performance than the conventional DVC algorithms, as well as reduces the decoding complexity significantly.
