What is S-Video?S-Video is a video transmission standard that was developed in the 1980's in order to provide superior picture resolution versus ordinary composite video. S-Video is transmitted in two parts: luma (Y) and chroma (C). In contrast, composite video is transmitted as one signal that combines chroma (color) and luma (luminosity). By transmitting chroma and luminosity separately, S-Video achieves a sharper picture versus composite video.
S- Video cabling is characterized by a four-pin mini DIN connector that contains two pairs of wires - one pair for Y and another for C.
