越来越多的大屏幕彩电都有一个S—Video接口,俗称S端子。S端子的“S”是英文“Super”的字头,译为“超级”,换言之,它是指高清晰度视频信号的接口。普通彩电大多具有AV端子,它是用于直接接收图像和声音信号的接口。从录像机或影碟机拾取的经过处理的可供彩电重放图像的视频信号,输入彩电的视频端子(即AV状态),经过输入切换,由色度电路和亮度电路分别处理,再送矩阵电路,通过解码组成三基色视频信号,最后通过R、G、B三路视频放大输出去调
More and more large-screen color TV has a S-Video interface, commonly known as S-Video. S terminal of the “S” is the English “Super” prefix, translated as “super”, in other words, it refers to the high-definition video signal interface. Most of the common color TVs have an AV terminal, which is an interface for receiving images and sound signals directly. Processed from the VCR or DVD player for color image playback video signal input color TV video terminal (ie, AV state), after the input switch, the chrominance circuit and the brightness of the circuit were processed, and then sent to the matrix circuit, through the Decoding composed of three primary color video signal, and finally through the R, G, B three-way video amplifier output to tune
