ated by the camera and usedby the picture monitor to pro-
duce a picture. The same signalsmay also be called “GBR”
as a reminder of the mechanical sequenc e of connections in
the SMPTE interconnect standard.
R--Y Oneof the color difference signals is obtaine dby sub-
tracting luminance(Y) from the red camera signal.
Saturation The property of color whic h relates to the
amount of white light in the color. Highly sat urated colors
are vivid, whileless saturated colors have more whitemixed
in and, therefore, appear pastel. For exam ple, red is highly
saturated, whilepink is the same hue, but much less satura-
ted.
In signal terms,saturation is determined by the ratio between
luminance level and chrominance amplitude. It should be
noted that a vectorscope does not display saturation; the
length of the vectors represents chromi nance amplitude. In
order to verify that the saturation of the col orsi n a color bar
signal is correct, youmust check luminance amplitudes with
a waveform monitorin addition to observing the vectors.
SCH The timing relationshipbetween the horizontal sync
pulses and the zero crossings of the reference subcarrier
(burst).
Setup In NTSC systems, video black is typically 7.5 IRE
above the blanking level. This 7.5 IRE level is referred to as
the black setup level, orsimply as setup.
SMPTE Societyof Motion Picture and Television Engi-
neers.
SMPTE Format In component te levision, this refers to
the SMPTE standards for parallel analog component video
interconnection. The SMPTE has standa rdized both RGB
and Y,PB,P
Rcolor differencesystems.
Subcarrier The modulation sidebands of the color subcar-
rier contain the R--Y(V) and B --Y (U) information. For
NTSC, subcarrier frequency is 3.579545 MHz. For PAL,
subcarrier frequency is 4,433,619.75 Hz.
