随着微型计算机技术在电视录像设备中广泛应用,电视设备的控制系统发生了重大的变化.RS-422接口是计算机通用的串行数据传送接口,它在电视录像设备中被用作遥控接口,使电视录像设备之间可以有较长的通信距离,此接口解决了录像机与录像机、录像机与编辑机、录像机与其它电视设备之间相互遥控的问题,满足了某些电视设备远距离遥控操作的要求,为实现计算机控制电视节目的制作和播放提供了条件.RS-422接口与目前使用的RS-232C串行接口相
With the widespread application of microcomputer technology in video recording equipment, the control system of television equipment has undergone major changes.RS-422 interface is a universal serial data transmission interface for computers, which is used as a remote control interface in video recording equipment, So that there is a longer communication distance between video recording devices. This interface solves the problem of remote control between video recorders and video recorders, video recorders and editing machines, video recorders and other television devices, and meets the requirements of remote control of some television devices Requirements, in order to achieve the computer-controlled television program production and playback provided.RS-422 interface and the current use of the RS-232C serial interface phase
