摘要
传统的码率控制算法不适合于无线环境中转码器的码率控制。在随机最优控制理论的基础上,提出了一种自适应的码率控制算法。该算法能在传输的实时性和播放的连续性之间进行平衡,力图取得最好的综合性能,同时能很好地适应带宽变化,并尽可能地提高带宽资源利用率。
Traditional rate control algorithm is not fit to be used in transeoder in wireless environment. An adaptive rate control scheme based on the theory of stochastic optimal control was proposed. It can balance real-tlme transmission with continuity of video playing and attempt to aequire the best overall performance. In addition, it can be adapted to the change of bandwidth and make the best of the bandwidth.
