High Performance Video Processor for Color Television

An integrated circuit has been developed that has advanced video processing for color television. Chroma and luma signals are processed to develop red, green and blue output signals. Improved accuracy is achieved in subcarrier regeneration. Chroma demodulation recovers the full NTSC I signal. The luminance channel has automatic control and a non-linear processor. Strict control of black level is maintained for interface to a kinescope bias controller. A digital RGB on-screen-display is described with automatic fast blanking.
