Abstract
A video display deflection circuit includes a source of a video signal for displaying picture information contained in the video signal in a screen of a cathode ray tube. The video signal on-provides selectively an on-screen-display information and a non-screen-display information. A source of a first control signal has a first value, when the video signal provides on-screen-display information and a second value, when said video signal provides non- on-screen-display information. A comb filter responsive to the first control signal has selectively a first delay element, when the first control signal is at the first value and a second delay element, when the first control signal is at the second value. The filter selectively establishes, in accordance with the first value, a first frequency response characteristic and, in accordance with the second value, a second frequency response characteristic. The filter is responsive to a video signal for generating from the video signal a filtered correction signal having a frequency spectrum in accordance with the values of the first control signal. The correction signal is coupled to an auxiliary deflection winding to produce, in accordance therewith, scan velocity modulated deflection of the electron beam.
