■ Component video signal
With the component video signal system, the video signal
is separated into the Y signal for the luminance and the P
B
and P
R
signals for the chrominance. Color can be
reproduced more faithfully with this system because each
of these signals is independent. The component signal is
also called the “color difference signal” because the
luminance signal is subtracted from the color signal.
A monitor with component input jacks is required in order
to use the component signal for output.
■ Composite video signal
With the composite video signal system, the video signal
is composed of three basic elements of a video picture;
color, brightness and synchronization data. A composite
video jack on a video component transmits these three
elements combined.
■ S-video signal
With the S-video signal system, the video signal normally
transmitted using a pin cable is separated and transmitted
as the Y signal for the luminance and the C signal for the
chrominance through the S-video cable. Using the
S VIDEO jack eliminates video signal transmission loss
and allows recording and playback of even more beautiful
images.
