| 摘 要： | 无线移动网络环境稳定性较差，需要研究如何自适应有效带宽的动态变化，以获得最佳的视频监控效果。H．264是高压缩比的视频编解码标准，相同条件下需要的传输带宽更少。RTP/RTCP协议专为实时数据的传输而设计。本系统中，视频采集终端用RTP协议封装和发送H．264数据，用RTCP协议接收网络传输质量信息，自适应调整发送速率；监控平台对收到的数据进行整理和过滤，确保视频图像的正确播放。实验表明该设计在无线移动网络环境下，视频监控效果良好。

| Abstract: | As wireless mobile network is usually unstable ,it is necessary to study how to automatically adapt to bandwidth variation for the best result of video monitoring. H. 264 is a video coding standard with high compression ratio,, which needs less bandwidth under the same conditions. RTP/RTCP are designed for real -time data transmission. In this system, the video captures terminal packages and sends H. 264 data with RTP, and it receives network transmission quality with RTCP, automatically adjusting transmission rate; the monitoring platform organizes and filters data received, and plays video correctly. Experimental result indi cates that this design could achieve good results of video monitoring in wireless mobile network environment. |
