摘要： 针对如何让RTP传输音视频流在尽量短的时间内让发送端达到最佳发送速率这一迫切需要解决的问题,提出了连续媒体流的快速匹配最佳发送速率算法.对RTCP中计算下一个RTCP RR分组的发送时间进行了改进,使得发送端通过RTCP反馈信息迅速探测当前网络的状况,并及时地调整自己的发送速率,尽量减少对多媒体传输稳定性的影响.模拟结果满足实时性的要求.

Abstract: To transmit the RTP-based audio/video stream as soon as possible so as to enable the sending terminal to get an optimal transmission rate is a problem to be solved urgently. An algorithm for optimal transmission rate that can be matched rapidly is therefore proposed for continuous medium stream. The algorithm improves the transmitting time for the next RTCP RR packet, which is required to compute in RTCP(real-time transport control protocol), thus making the sending terminal search quickly the current situation of network through RTCP information feedback and readjust timely its transmission rate to lower its influence on the stability of multimedia transmission. Simulation meets the require of real-time requirement.
