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
