Component video cables do not carry the audio, a seprate audio cable is required. Connectors are often marked YUV or YPbPr.




composite-videoComposite Video Cable

A composite video cable has a single phono (RCA) plug each end, the plugs are colour coded yellow, this connection provides the lowest quality analogue video connection and should only be used if scart, component or s-video cannot be used. A separate cable must be used for audio.




s-video-cableS-Video Cable

The s-video cable has a 4 pin mini-din connector each end and transfers the video signal as two components, Y (luminance) and C (chrominance), it gives a better picture than composite video but is not as good as RGB via scart or component video. S-Video cables only transfer the picture and give a quality not far behind RGB scart.
