S-Video stands for Super Video, it provides means to transmit video signals by dividing the video information into two separate signals: one for color (chrominance), and the other for brightness (luminance). S-Video produces higher video quality than single wire composite video, but is lower video quality than Component Video Signals(YPbPr). S-Video is also known as Y/C video. To use S-Video, you need a special S-Video cable to connect the two devices that support either S-Video output or input.
