Research of remote video transmission adaptive control technology based on virtual desktop

With the continuous development of cloud computing, virtual desktop solutions are becoming more sophisticated. But the virtual desktop transmission system is still unable to guarantee the quality of remote video transmission service which has the characteristics of real-time and continuous. In order to improve the performance of remote video transmission system, an adaptive control mechanism for video transmission based on real time transport protocol (RTP) is proposed. In this mechanism, the network status is detected by calculating the one-way delay at the receiving end, and according to the statistical information of network status to forecast the future network status by using Markov model, and the encoding rate of the sending end is adjusted. So, the transmission delay can be reduced, and the video transmission quality is improved. After testing, the average delay of the data stream is reduced by 30%, which effectively improves real-time performance of the remote video transmission service.
