2-1-1979 1 PHN 9191 ABSTRACT: "Colour selection circuit for colour television". A colour selection circuit for colour television, for example for chroma-keying signal generation. The signal generation is done independent of the luminance and depends only on the colour with which a given combination of input signals corresponds. This is effected by the use of an equal-signal detection behind amplifier circuits to which input signals, having a predetermined peak-peak value are applied and at least two of these input signals have been set with a given attenuation factor with respect to a third, which setting determines the colour at which the keying or switching signal is generated.
