  • Patent number: 5612710
    Abstract: A large scale video display of the present invention is designed to receive a standard NTSC video signal and display it on a large scale array of low cost, voltage or current controlled lamp transducers. The video signals are received by a video capture device which receives and digitizes the video signal. A host processor formats the digital data into a number of 16 bit data words each corresponding to a pixel. A coprocessor receives the 16 bit data words and reformats the data. The reformatted data is connected to a large scale display by a fiber optic connection. The display includes a number of transceivers which receive the formatted video data in a memory buffer. The transceivers also receive a board map from the coprocessor. The map indicates which light boards correspond to each part of the memory where the frame image is stored. This information is used by a number of controllers to determine which lights to turn on and at what level of brightness for any given time.
