【摘要】 针对网络视频应用交互性、实时性、突发性、数据量大等特点,设计并实现一个基于RTP/RTCP的端到端的视频流传输框架.通过反馈控制协议自适应地调整视频传输码率,提高视频应用的服务质量并达到对网络带宽的高利用率.测试结果表明在网络状况波动的情况下,视频流自适应传输框架具有较高的网络利用率和较低的包丢失率.更多还原

【Abstract】 With video network applications’ specific properties,as interactive,burst,realtime and it’s large data amount,this paper designed and implemented an end-to-end self-adaptive video stream transmitting framework.By realizing RTP/RTCP,it can vary the video bit rate adaptively according to the network,and improves the quality of service of the video applications,meanwhile increases the utilization of the network bandwidth.Testing result shows that when network bandwidth jitters,the framework works well.更多还原
