摘要
根据视频监控系统可区分视频流和控制信息流,且视频流单向流动,控制信息流双向流动的特点,提出了基于物理双通道技术的视频监控安全接入技术,即利用单向通道传输视频流数据,双向数据交换通道传输控制流数据。辅以视频协议检查等其他技术,实现了安全的视频监控安全接入系统,并以目前流行的基于SIP协议的视频监控系统为例进行了分析和具体实现。
Data stream of the video monitoring system could be separated into one-directional video data stream and hidirectional instruction data stream. In the light of this feature, a security access technology based on dual-physical channel for video monitoring is proposed in this paper. The dual-physical channel is composed of a one-way channel and a twoway channel. The one-way channel is used to transmit video data stream, and the two-way channel to transmit instruction data stream. The dual-physical channel technology, video application protocol analytical technology and other technologies constitute the security access system for video monitoring. A typical video monitoring system based on SIP protocol is analyzed, and a security access system is implemented.
