Abstract
Apparatus for simultaneously controlling the contrast of broadcast color video signal information and auxiliary color graphics information displayed by the kinescope of a color television receiver. Plural kinescope color signal coupling paths receive color video signals, a white drive graphics signal which is applied in common to the plural signal paths with a sense for enabling the kinescope to display color graphics information during graphics intervals, and plural blanking signals which are separately applied to the color signal paths for selectively blanking the outputs of the signal paths to determine the color of displayed graphics information. A picture control signal simultaneously varies the level of the color video signal and the level of the common white drive graphics signal in the same sense.
