Abstract
A novel framework for rate-distortion (RD) analysis is developed. Based on this framework, an optimum bit allocation scheme and an accurate rate control algorithm are proposed for real-time video coding with H.263+ (see Cote, G. et al., IEEE Trans. on Circuits and Systems for Video Technology, vol.8, p.849-66, 1998). With the proposed algorithm, the picture quality is significantly improved. The output bit rate of the video encoder is controlled robustly and accurately according to the network condition
