S端子针脚定义
S端子针脚定义英文简介：Plug——插头；connector——端子；三、S端子S-connector: EIAJ CP-1211, IEC 84(s)801脚——亮度信号地Luminance (Y) signal ground
2 脚——色度信号地Chrominance (C) signal ground
3脚——亮度信号输入输出Luminance (Y) signal I/O (1 Vp-p, 75 ohms, sync: negative)
4 脚——色度信号输入输出Chrominance (C) signal I/O (burst: 0.286 Vp-p, 75 ohms)
