Abstract:In this paper a novel method of dynamic rate adaptation for streaming media server based on RTP Control Protocol is developed and implement. Several key control parameters including ratio of lose packet, jitter and size of free buffer are obtained by analyzing received RTCP RR packets and RTCP NADU packets. The rate-switch direction in server-end can be got bysetting threshold via these parameters and sending-rate after switching come from integrative calculation with estimating bandwidth and adjusted sending-rate of control parameters. Experiment results show that the benefits of this method are anti-surging, predicting bandwidth, responding to network diversification rapidly and controlling overflow and underflow of buffer effectively.
