摘要： 提出了的视频实时传输体系结构,采用基于实时传输协议()和实时传输控制协议()的反馈拥塞控制算RTP/UDP/IPRTPRTCP法,控制发送端视频编码器输出的比特率,以使得整个基于的网络视频传输系统既能充分利用网络带宽又不引起网络拥塞,从而减少时IP延,降低丢包率,为视频数据的接收者提供一个较好的图象质量。

Abstract: Since packet loss and delay are usually caused by network congestion, we present a feedback congestion control scheme basedon real-time transport protocol (RTP) and real-time transport control protocol (RTCP), which can satisfy the real-time video delivery system with loss and delay requirements. The paper first shows our design motivation, then introduces the real-time video transportation architecture using the RTP/UDP/IP protocol stack and discusses our feedback congestion control algorithm in detail. Finally, we compare our real-time transportation system with other video transportation systems based on UDP or TCP.
