【摘要】：针对南水北调中线工程在异构网络下的视频监控传输问题,提出了一套包括基于网络状况的带宽评估方法,以及参数可调的网络视频编码传输方式的异构网络视频监控解决方案.该方案对南水北调工程异构网络环境下视频监控系统的整体架构进行了设计,并基于实时传输协议/实时传输控制协议(RTP/RTCP)对网络参数进行了评估.在得出的网络带宽评估结果基础上,设计了一种码率可调的编码传输方案.最后结合所实现的系统,对系统性能进行了详细测试和分析.通过在南水北调中线工程的实际应用证明,本系统能够对当前带宽下的视频编码进行优化,提高异构网络下的视频编码传输效率,且性能指标达到了4路720P视频监控的设计要求.
[Abstract]:Aiming at the problem of video surveillance and transmission in heterogeneous network for the middle route project of South-to-North Water transfer Project, a set of bandwidth evaluation methods based on network condition are proposed. And the solution of heterogeneous network video surveillance in the network video coding transmission mode with adjustable parameters. This scheme designs the whole frame of the video surveillance system under the heterogeneous network environment of the South-to-North Water transfer Project. The network parameters are evaluated based on RTP / RTCP. based on the result of network bandwidth evaluation, a coding transmission scheme with adjustable bit-rate is designed. The performance of the system is tested and analyzed in detail. Through the practical application in the South-to-North Water transfer Project, it is proved that the system can optimize the video coding under the current bandwidth and improve the transmission efficiency of the video coding under the heterogeneous network. And the performance index meets the design requirements of 4 channels 720P video surveillance.
