Design Scheme for the Transmission of Video and Control Signals in a Single Common Cable

介绍图象和控制信号共缆传输设计方案，关键技术是在场消隐期间传送控制信号。

This paper introduces a design scheme using a single cable to transmit simultaneously video signals and control signals,in which the key technique is the transmission of control signals in the vertical blanking interval of video signals.Practical circuits and testing waveforms are given in the paper.
