This paper proposes an idiographic implement scheme of MPEG-4 real-time video streaming for multi-channel based on RTP/RTCP over WLAN. It also proposes an effective synchronistic model for multi-channel video based on timestamp synchronization. Aiming at the wireless QoS mechanism, this system applies to an ECN algorithm based on RTCP feedback rate control algorithm-TFRC. The ECN algorithm improves the TFRC algorithm, adjusting the sending rate dynamically according to ECN-marked packet probability to realize congestion controls. Experiments show that the transmission method can obtain good video transmission quality
