Composite cable is the most common way for video signal transmission. Composite video signal is a composite of luminance (Y) and chrominance (C). It adopts RCA plug designs for easy connections. You will find its application throughout home electronics devices-from TV, VCR, to DVD players. It usually pairs with two other RCA cables for stereo audio signals, to completely deliver all the video and sound that you need. S-Video Cable Unlike composite video cable, S-Video splits the video information's lumninance (Y) and chrominance (C), which adds clarity to the video display to provide more subtle images. Most video equipment is equipped with the S-Video feature. As with the composite cable, it often pairs with two RCA stereo audio cables.
