COLOR
(Continued):
Ideally, television cameras would keep the three basic
signals (Red, Green, and Blue) separate to get the best
possible quality.
(Computers
DO keep red, green and blue separate, by the way. That's
why your computer cable has so many pins. And it's why
your computer's colors are so vivid!).
Some
TV equipment actually does keep the colors separate.
These devices are called "component."
(We mentioned this in the VCR unit, but it's worth a
reminder here.)
Component devices are a hassle because you need three
wires every time you want to send a signal from one
place to another.
So
instead, we typically mix these signals (Red, Green
and Blue) together to route them around. The process
of mixing is called "encoding." Later
on we unmix or "decode" the red, green,
and blue signals to re-create the color image.
