ABSTRACT:
A killer signal generator for use in a color television receiver having an information processing circuit for processing specific information such as VIR information contained in a line during the vertical blanking interval. The killer signal generator comprises a line pulse sampling circuit for generating pulses synchronized with the line in which the specific information is contained, a D.C. restorer for restoring D.C. component of a series of video information, which includes a differential pair composed of first and second transistors, the first transistor having a base receiving the video information including the specific information while the second transistor has a base connected to a constant reference potential and an input end adapted to receive the video information through a capacitor, and for generating D.C. restored output corresponding to the specific information, and a killer signal generator for generating an operation signal for enabling the information processing circuit when the color television receiver receives video information with the specific information and also a killer signal for bringing the information processing circuit into an inoperative condition when it is not.
