本标准定义了用于演播室应用的组件模拟视频接口，该接口使用平行通道上的三个基色信号，用于电视设备的互连。通过接口传输的信号具有525行、59.94场/秒、2:1交错和4.3或16.9纵横比的典型扫描结构。信号具有一个垂直消隐间隔，该间隔被分为一个活动行周期和一个水平消隐间隔。信号特征由一组经过伽马校正的红色、绿色和蓝色R'G'B（以下定义为RGB）主视频信号定义。除了在RGB组件模拟操作级别对电视设备进行一般互连外，本标准定义的信号适用于作为符合ANSI/SMPTE 125M和ANSI/SMPTE 267M的模数转换系统的输入，或作为符合ANSI/SMPTE 170M的NTSC复合编码器的输入。 本标准定义的三通道接口（绿色同步）是首选实现。某些应用程序可能需要四通道接口（单独携带同步）。附件A中描述了这种实施。

This standard defines the component analog video interface for studio applications using three primary color signals carried on parallel channels for the interconnection of television equipment. The signals carried across the interface have a typical scanning structure of 525 lines, 59.94 fields/s, 2:1 interlace and 4.3 or 16.9 aspect ratio. The signals have a vertical blanking interval that is divided into an active line period and a horizontal blanking interval. Signal characteristics are defined by a gamma-corrected set of red, green, and blue R'G'B' (hereafter defined as RGB) primary video signals. In addition to general interconnection of television equipment at the RGB component analog level of operation, the signals defined by this standard are suitable as inputs to analog-to-digital conversion systems in compliance with ANSI/SMPTE 125M and ANSI/SMPTE 267M or as inputs to NTSC composite encoders in compliance with ANSI/SMPTE 170M.The three-channel interface defined by this standard (sync on green) is the preferred implementation. Some applications may require a four-channel interface (with sync carried separately). Such an implementation is described in annex A.
