Composite means its all of the video components (the brigthness and the 3 colours red green blue) on one cable. They are all mangled together in a cleaver way (PAL) so colour tv can be transmitted a a single signal over the airwaves (and so that black and white tv's can receiver colour broadcasts but ignore the colour)
This is good but not great.
RGB is 3 cables, one for each colour. Its what the camera produces and what your old skool tube telly uses to display the picture with. Much better quality as it doesn't get mangled at the tv studio into one signal then un-mangled in your telly. Problem is you would need 3 transmitters on the hill top and thats very expensive! Oh...and black and white tellys would have stopped working when the UK went colour!
SVideo is a half way house and used in VCR's. One signal cable carries the brightness (black and white) and the other carries the colour infomation. Thats why some people only get black and white if they connect or configure stuff wrong! The luminence component (brightness) is a larger bandwidth singal compared to the colour. It would be wasteful otherwise becuase human eyes an't that sensitive to colour, more so to brightness.
Clear as mud!?
