基于无线局域网的实时视频传输与控制
Real-time Video Transmission and Control over WLAN
【摘要】 针对无线局域网,研究实现了一种基于RTP/UDP/IP协议的端到端H.263实时视频传输系统。针对无线QoS机制系统应用了一种RTCP反馈友好码率控制算法TFRC,根据丢包率来动态调整发送码率实现拥塞控制。实验表明该传输方案能获得较好的视频传输质量。
【Abstract】 This paper studies and implements an end-to-end system of H.263 real-time video transmission based on RTP/UDP/IP over WLAN. Aiming at wireless QoS mechanism, this system applies a RTCP feedback rate control algorithm-TFRC which can adjust the sending rate dynamically according to the packet loss rate to realize congestion control. Experiments show that the transmission method can obtain good video transmission quality.
