Currently S-Video signals generally use 4-pin (pin) of the mini-DIN connector terminals, terminal impedance shall be 75 ohms, and otherwise generally no different mini-DIN cable (such as the use of Apple ADB) PR Which terminal block deal, when there is no dedicated S-Video cable, these mini-DIN cable can be as S-Video signal transmission purposes, but the picture quality may not be so good. Video signal is separated into two parts luminance and chrominance PR terminal block Which promotions, so S- terminal is sometimes seen as a composite image signal PR terminal block where the good, but in terms of the quality, S- Video is a component signal in the worst kind, far more complex than other component video signals (such as RGB). The difference between S-Video and component video these higher order that, S-Video signals will be combined into a color signal for transmission, so color signals must be encoded, and the NTSC, PAL or SECAM video signal transmission, etc. S-Video Jieyou different coding when transmitted. So in order to achieve full compatibility between signals, you must take into account both the S-Video connector and color coding compatibility. Which terminal block Guancheng cheap electronic products factory Song Chong-wook, PR terminal block from the Dongguan Shijie Xu Song Chong electronic products factory provided.
