RCA 77,370 Abstract of the Disclosure Auxiliary graphics information signals to be displayed by the kinescope of a television receiver during on-screen display intervals are applied to the kinescope via a video signal coupling path of the receiver by means of a gated transistor and a differentially controlled current steering switch which are controlled by graphics timing signals. A current source for the current steering switch supplies an operating current for the video path when normal video signals are to be displayed, operating current for the gated transistor when graphics signals of a color other than black are to be displayed, and operating current for blanking the video path to produce a black graphics display.
