Um... No. Sorry. Close though.

The other two signals are the quadrature components of
chrominance.
They are derived from Y by subtracting red and blue, and are normally
called U and V (in some order).
Aha! YUV is something I recognize now. I believe this is what broadcast
professionals call component video. (Let's see if I'll be right one out of
two.)
The signals are transmitted this way in broadcast TV
to ensure
compatibility between colour and BW tellies. They are also the signals
that would normally be sent to a TV (UHF or VHF) modulator from the
computer, hence their presence on the video connector.
Hmmm... any modulator I've ever worked on had a composite input. Is this
maybe more common in European systems?
Hope this helps! I could be more specific if I had
some of my reference
books from home...
Specific enough for me. Thanks.
Philip.
