Everyone else's uses the standard plugs. (whatever the hell they're called) -----End Message----- Mike, Don't get composite and component mixed up. Composite Video typically uses one RCA, F-Type, or one BNC connector at each end of a 75-ohm coaxial cable to transmit all the signals required for colour video: luminance (brightness) and chrominance (colour). Video colour modulation schemes such as NTSC (National Television Standards Committee) and PAL (Phase Alternation Line) are examples of composite video. Cable TV often includes sound within your cable TV connection. S-Video uses MiniDin 4-pin connectors at each end of a cable that has two small 75-ohm coaxial cable lines running within it. S-video keeps the luminance signal (brightness signal) and chrominance signal (colour signal) separated. One line (or pin) carries the luminance signals, one carries the chrominance signals, and the other two lines (or pins) each are ground wires. Adding the luminance and chrominance signals together produces a composite video signal (above). S-video is also known as Separate Video or Y/C video because the Y signal (brightness) and C signal (colour) are separated. S-video is designed to provide a better quality picture than composite video. Component Video typically uses three RCA connectors or three BNC connectors at each end of a cable consisting of three separate 75-ohm coaxial cable lines within it. However, three individual 75-ohm coaxial cables with the same connectors can also be used. Component video separates the luminance signal (brightness signal) from the sub-components of the chrominance signal (the blue signal and the red signal). Notice that blue and red will produce green to achieve a completed RGB (red, green, blue) signal. Component video is designed to provide a better quality picture than s-video. RGB Video typically uses four or five RCA or BNC connectors at each end of a cable consisting of four or five individual 75-ohm coaxial cable lines within it. Again, these can be four or five individual 75-ohm coaxial cables. (Compare RGB Video with Component Video above, as they are often confused.) RGB video typically describes a computer video signal, not a television screen signal (which are typically NTSC signals or PAL signals). RGB signals are incompatible with NTSC and PAL signals, however special adaptors can be purchased to convert between them. The first three lines carry the red, green, and blue signals (the RGB signals) separately. The other two lines carry the horizontal sync and vertical sync (which can be combined into one line).
