ABSTRACT:
A multiplying video mixer system including a digital signal generator for generating at least one overlay signal and an attribute control bit corresponding to each of a plurality of pixels. A background signal generator generates input background signals to which the attribute control bits are applied to effect the input background signals with a desired opaque/transparent attribute. At least one video multiplier multiplies the overlay attribute signals and background signals to produce an output video signal having an amplitude equal to the product of the amplitudes of the overlay and background signals.
