Whats the difference between S-Video, composite and component connections?
To understand this answer you need to know that a video signal is comprised of Luminance (brightness/contrast and sync, abbreviated to Y) and Chrominance (the three colours – Red, Green and Blue, abbreviated to C.) Composite: The lowest quality cable comprising a single copper or coaxial wire with either a phono, BNC or SCART connection. The Luma and Chroma signals are mixed and sent down the same cable leading to reduced image quality. S-Video: (Also known as Y/C) A single coaxial cable with a 4-pin mini DIN connection (but can also be integrated in a SCART cable). The Luma signal (Y) and Chroma signal (C) are separated and sent to different pins. They are recombined on input. This type of cable gives better quality than composite. Component: (Also known as Y U V, or Y Cr Cb) The best quality cable, comprising 3 copper or coaxial wires, generally with BNC connections (but can also be integrated in a SCART cable). The Luma is sent down one wire and the other wires contain the Red (Cr)
