Composite
(Baseband)
A band or grouping of frequencies and/or subcarriers,
including video, occupied by the signal in a radio
transmission system. Also called Baseband.
Composite
Video
Video signal in which the chrominance (color) and
luminance (brightness) information are combined in
one signal. S-Video separates the chrominance and
luminance into separate signals.
