Section VII. TEST SIGNAL DESCRIPTIONS
S-23. Full-Field Color Bars.
The full-field color bar (Figure S-30) signal is used to check and adjust color picture monitor and
receiver luminance, hue, and saturation levels. The signal represents a scene with high brightness and
saturation.
Figure S-30. Full-Field Color Bars
S-24. Split-Field Color Bars.
In addition to the full-field signals, some generators can provide a split-field color bar signal. This
signal consists of the luminance portion of the color bars signal on each active line of each field; the
chrominance portion of the color bars signal are only on lines 66 through 218 of each field. This signal
allows checking black-to-white tracking and the color encoding simultaneously. See Figures S-31 and
S-32.
