Abstract
A large display system capable of displaying a video image receives video signals, quantizes those signals to produce a digital code capable of representing variations in the light content of the image and processes the digital code so as to control individual display devices on a large matrix of such devices to have different levels of visibility to thereby reproduce the video image for viewing by a large audience. A data processor is optionally utilized to store the digital representation of the video image in memory so that on line or off line presentations can be made.
