Abstract

In the light of the high decoding complexity and large transmission delay caused by the bit rate allocation of Distributed Video Coding (DVC) scheme with feedback channel, this paper proposes an improved bit rate control algorithm without feedback. The algorithm uses the division of macro block to simplify the bit rate allocation, and switches Laplacian parameters in the Correlation Noise Model (CNM) between the block-level and frame-level to adjust rate based on the intensity of motion. The simulation results show that the proposed algorithm can accurately control coding bit rate and transmission delay only at the cost of a small amount of coding complexity, and effectively guarantee the rate-distortion performance of DVC system.
