带宽自适应网络视频监控系统的研究

With the development of computer technology, image processing technology and network technology, network digital video surveillance systems have been widely used. This paper analyzes the application of RTP / RTCP in the network real-time video surveillance, and proposes a network-bandwidth adaptive network real-time video surveillance system design. It elaborates how to use the RTP / RTCP to estimate the state of the media transport network and proposes a simple and effective network bandwidth estimation method. Then, the video capture front corrects the output bit rate level to adapt to the current network bandwidth. Based on Live555 streaming media library, it designed the server and the client of video surveillance system as an experimental platform. The experimental results showed that the design of the program achieved the intended purpose.
