ABSTRACT:
The apparatus is an interface to convert an input analog video signal (real-time) into an output to drive a matrix of light-emitting-diodes. Alternately, a digital video signal can be received, bypassing the analog-to-digital converters. The apparatus is readily configurable to various sizes of matrix sizes and uses a logic board to arrange the data so that low speed components may be used. Two frame buffers alternately receive data in random access order in accordance with the physical and data format of the LED display, and output data by direct memory access methods.
