Abstract

With the improvement of living standards, most people are used to driving. At the same time, the transportation is also becoming increasingly crowded. Thus, the traffic monitoring and accident treatment is becoming more and more important in China. In order to solve the problem of fixed camera in the monitoring blind area, a real-time video transmission system based on the 4G mobile network was proposed. Firstly, briefly introduce the overall framework of the system and the high concurrent I/O multiplexing method based on the Reactor model. Then, present a novel sender rate control method based on the dynamic buffer for the QoS(Quality of Service) of mobile video. And, experimental results have also been illustrated and analyzed to show that the transmission of mobile real-time video in our system is stable on the 4G mobile network. On the other hand, our system also ensures the high definition of mobile real-time video and it can be applied to the real-time traffic monitoring
