TELEVISION RECEIVER WITH AUXILLIARY INPUT CONNECTOR FOR VIDEO SIGNALS OF A SEPARATED Y-C FORMAT |
摘要 |
An auxiliary video input terminal (S-terminal) couples luminance amd chrominance input signals to respective inputs of peaking circuits in the display processor of a receiver. The chrominance input signal is subjected to pre-distortion (de-peaking) to correct for sideband amplitude distortion in the chrominance peaking filter of the receiver thereby preventing color distortion in displayed images. The luminance signal is subjected to additional peaking at a frequency greater than the characteristic peaking frequency of the luminance peaking filter thereby enhancing the sharpness of wideband luminance input signals displayed by the receiver.
