NTE1593
Integrated Circuit
Colot TV VIR Processor
Description:
The NTE1593 is designed for automatic adjustment of the color saturation and tint of color television
receiver.
Functions:
D Identification of line 19 and the detection of the presence of a VIR signal
D The development of dc color−controlling voltage by processing the VIR portion of the receiv-
er’s simulated blue drive signal
D The development of dc tint controlling voltage by processing the VIR portion of the receiver’s
demodulated R−Y signal
