Component Video
Component video consists of three signals.
The first is the luminance signal, which indicates brightness or black & white
information that is contained in the original RGB (red green blue) signal. It is
referred to as the Y component.
The second and third signals are called color difference signals indicating the
quantum of blue and red signals compared to luminance. The blue
component is Y-B and the red component is Y-R. Green is not transmitted as
a separate signal since it can be inferred from the Y, Y-B, and Y-R
combination.
Component video inputs are available on modern high-end television sets
and DVD players, providing a signal quality that is superior to earlier systems
such as RF, composite, and so on.
