摘要
视频总线技术是实现多传感器视频资源共享的新概念,它的基本功能是以总线形式传输搜索雷达、跟踪雷达、电视/红外等视频信号,它的基本原理是多路视频信号调制不同的载波,利用频分传输的原理,用一根同轴电缆传输至各显控台,每个显控台解调恢复出这些信号供给综合显示用,这样可以大大减少整个系统视频信号的传输电缆。
Video bus technology is a new concept for accomplishing video resource sharing of shipboard multi-sensors. Its basic function is transmitting video signal （search radar, tracking radar, TV/IR equipment, etc. ） in form of bus. Its basic principle is that： multiplex video signal modulates carrier waves with different frequency. A coaxial cable is used to transmit carrier wave to each console, by using frequency division principle. Each console demodulates and restores the signal for integrated display. Thus we can reduce the transmission cable greatly for video signal of the whole system.
