Abstract:

A real-time H.264 video stream transmission system that based on standard RFC is designed and implemented in this paper. In order to overcome the adverse factors as high bit error and low bandwidth through the wireless channel,this paper proposes UDP/RTP virtual links that under the cdma2000 EV-DO to ensure real-time transmission. At the meantime,in order to make up the lack of AIMD algorithm,this paper uses Gilbert channel model to estimate the effective bandwidth,and adjusts the sending rate by predicting the bandwidth. The results show that when the network congestion occurs,the system will automatically reduce the video frame rate to ensure real-time video transmission,since the RTCP feedback mechanism is added.

Key words: H.264, EV-DO, RTP, RTCP
