Bar
Each time you press COLOR BAR, the color bar type switches in the following order:
Full field color bar, multi format color bar, SMPTE color bar.
The color bar types that can be transmitted vary depending on the output format and aspect
ratio (see Table 12-2, “List of output patterns”).
Color bars are used to test the level, hue, and other parameters on video equipment and to
adjust or test the hue, saturation, brightness, and contrast on monitors.
