Description:
A single DC picture control adjusts the gain of both the low鈥搇evel video and chroma amplification in
color TV receivers which employ the NTE818Luminance Processor. Automatic brightness limiting
(ABL) and vertical maintaining a constant black level. During the horizontal blanking interval, the
black level is determined by clamping the black鈥搇evel reference (the 鈥渂ack porch鈥?. This allows for
100% DC restortion.
