摘　　要：多媒体通信中一个很重要的服务质量指标就是视频数据传输的平滑度,但平滑度往往是与网络传输流量相矛盾的.文章正是针对这一矛盾,通过引入控制论的思想并利用神经网络预测流量的特征参数,提出了一种解决多媒体通信中视频数据流平滑的方案.通过实验模拟,证明了该方案能很好地解决多媒体通信中的这一矛盾,使视频流量和平滑度折衷后达到最优效果.： In multimedia communications,video smoothing is always a very important problem which people care for.It is one of the critical factors of multimedia communications QoS(Quality of Service).But the smooth degree is always conflict with networks throughput,that is,to enhance the smooth degree will inevitably reduce the networks throughput,and vice versa.To solve the problem,in this paper a solution based on control theory and neural network is presented.The simulation results show that the presented method has good performance in getting a compromised solution．

关 键 词：多媒体通信 视频平滑 视频数据传输
