B--Y(PAL) One of the colordifference signals used in the
PALsystem, obta ined by subtracting luminance (Y) from the
blue camera signal (B).
CAV Component Analog Video;compone nt video signals in
which an analog voltage or current (rather tha n a set of num-
bers) represents the value of the pixel; the same as “analog
components.”
Chrominance Chrominance refers to the color informa-
tion in a television picture. Chrominance can be further bro-
ken down into two properties of color: hue and saturation.
Chrominance Signal Thehigh-fre quency portion of the
video signal which is obtained by quadrature ampli tude mod-
ulation of a 3.58 MHz (NTSC) or 4.43 MHz (PAL) subcarrier
with R--Y and B--Yinformation.
Color Black SeeBlack Burst.
Color Correction Aprocess in which the coloring in a
television image isaltered or corrected by electronic means.
Care must be taken to insure that the modifi ed video does not
exceed the limits of subsequentprocessing or transmission
systems.
Color Difference Signals Signalsused by col or televi-
sion systems to convey color information in such a way that
the signalsgo to zero when there is no color in the picture.
R--Y,B --Y,I, and Q are all color differencesignals for the
NTSC system; U and V are color difference signal s for the
PALsystem.
Component Video Video which existsin the form of
three separate signals,all of which are required in order to
completely specifythe color picture. Forexample, R, G, and
B; or Y,R--Y,and B--Y.
Composite Video Asingle video signal contai ning all of
the necessary information to reproduce a col or picture.
Created by adding quadrature amplitude m odulated R--Y and
B--Y to the luminance signal for NTSC systemsor U and V
to the luminance signalfor PAL systems.
