The process of real-time video streaming across the Internet using TCP(transmission control protocol) was analyzed,and the sending-delays were found to be the critical influencing factors on the end-to-end delays of real-time video frame using TCP.A method that utilizes the sending-delays to judge the playing performance of the video frames was presented.A recursive Markov prediction model was proposed to predict the sending-delays of real-time video frames with input parameters as video frame lengths,network loss ratio,RTT(Round trip time) and TCP congestion window size.The NS2 simulator was introduced.The results show that the prediction value of video frame sending-delays can be used to determine whether it is feasible for a video frame to be transmitted using TCP,which provides importance reference for streaming transmission scheme based on TCP.
