移动网络视频传输速率自适应控制技术的研究
Research on Self-adaptive Control Technology of Video Transmission Speed in Mobile Networks
摘要
Abstract
Nowadays video transmission and interaction on mobile terminals is widely used. However,because the bandwidth of mobile network often fluctuates,it may lead the available bandwidth lower than the transmission speed and packets loss transmitted in network, which in turn affects the quality of video transmission and interaction. Thus how to change the transmission speed timely according to the change of network status,decreasing packet loss ratio in transmission,guaranteeing the quality of transmission and interaction,is very cru-cial. Aiming at the specific request of video transmission in mobile network environment,a self-adaptive speed control method applicable for mobile network video transmission is put forward. It improves the congestion control method used for TCP,and adjusts transmission speed dynamically according to the variation of network situation during the process of video transmission. The result of simulation shows that this method can guarantee the transmission speed change placidly within limits,which improves utilization ratio of network available bandwidth,and reduces packet loss ratio during transmission. Thus it can basically meet the requirement of video transmission and interac-tion quality in mobile networks.关键词
