摘要
In this paper, we present a rate control scheme for video over the Internet by adopting a fluid-flow traffic model and a new quadratic rate-distortion (R-D) model. Some simple control theory rather than a heuristic method is used to compute the target rate for each frame. Our scheme is better than some other existing schemes in the sense that our scheme can adapt itself in time to the variation of channel bandwidth, the number of skipped frames is reduced and the average PSNR is usually improved. Thus, our scheme is very attractive for video over the Internet.
