摘要：
Rate control plays a central role in constant bit-rate (CBR) video coding applications using MPEG-4. This paper considers single video object (SVO) rate control for MPEG-4 and presents a new rate control algorithm based on the quadratic rate-distortion model. Based on a new measure for the encoding complexity, the constraints of the model parameter estimation and a novel quantizer control strategy are proposed in this paper. Simulation results show that the MPEG-4 coder, using the proposed algorithm. can achieve a higher PSNR than a coder using the conventional rate control algorithm.
