摘要
随着国家平安城市等大型项目的推进,以安防为目的的视频监控行业得到了快速发展,视频监控系统呈现出了高清化和网络化的发展趋势。在整个视频监控系统中,高清监控视频在网络中的传输成为了限制发展的瓶颈问题。本系统设计了一套用于高清监控视频在网络中传输的自适应系统,采用图像分割后区别压缩的机制进行视频传输。同时加强系统对于网络环境的适应能力,在系统中实时地估计网络状态,动态调整发送速率,充分利用了网络带宽,又避免使网络陷入拥塞,很好地解决了高清监控视频传输对网络带宽的需求和网络带宽不足之间矛盾,到达了高清监控的目的。
With the progressing of some national projects such as the Safe City, the video surveillance industry for security has been having a rapid development, and the video surveillance systems have been allowing for high-definition cameras and connecting to the Internet. However, the transmission of the high-definition video has become the bottleneck for video surveillance systems. This paper presents a self-adaption transmission system for high-definition video, with the approach of image segmentation. Meanwhile the system enhances the adaption for network environment, dynamically adjust the transmit speed of system .according to the network environment, which not only making fully use of the network bandwidth but also preventing the network from congestion. The system effectively resolves the contradiction between the requirement of network bandwidth for the high-definition video and the bandwidth insufficiency.
