Abstract
With an elemental approach for producing a wipe surface, one or more identical wipe surface generator modular elements are cascaded together. Each element produces an elementary wipe surface, and the elementary wipe surface is cascaded to a next modular element to generate a complex wipe surface from a combination of the elementary wipe surfaces. A control signal generator receives the complex wipe surface and generates a video mixer control signal, .alpha., based on the complex wipe surface.
