摘　　要：传统的视频编码和正在发展的可伸缩视频编码,均采用变比特率编码。可伸缩编码流为适应动态网络传输和保持恒定的解码质量其裁减后的子流也是变比特率的,所有这些变比特编码流都会在传输中造成带宽的突发需求。提出一个如何平滑传输变比特率编码视频的RTP优化封装算法,在P2P流媒体系统中能实现RTP会话期间网络带宽的极小化占用,实验结果显示算法是有效而可行的。The encoded video exhibits significant data rate variability to provide a consistent quality video. This variability is faced with the problem of the available bandwidth utilization in P2P network transmission. Focuses on RTP re-encapsulating algorithm for the VBR encoded video to satisfy the minimizing consumption of network bandwidth and the smoothing transmission of VBR encoded video in P2P streaming environment. The experiment results show that our algorithm is feasible and effective.
