Abstract: A video to digital converter is disclosed for converting a frame of analog information received in raster fashion into digital data suitable for use in reproducing such a frame in a high speed video display system. An analog to digital converter is enabled to digitize all or only selected portions of the frame by means so as to produce data for reproducing an enlarged or magnified image of only a selected portion of the video frame or for reproducing substantially all the frame without enlargement. The digitized data is loaded into a display memory and is outputted via a display interface to a display board which may consist of variable intensity devices, such as, incandescent lamps. The system, although under computer control, does not include the computer in the data handling path thereby permitting increased data handling rates. The converter for the system includes circuits for changing the display format to produce "zoom" enlargements and wide screen displays suitable, for example, for racetrack applications.

Abstract: A high speed video display system suitable for use in operating video scoreboard displays is disclosed. Video data for a complete frame is converted from analog to digital format and is directly loaded into a display memory (RAM). The digitized data 18 then outputted via a display interface to the display board which may consist of variable intensity devices, such as, incandescent light bulbs. The system, although under computer control, does not include the computer in the data handling path thereby permitting increased data handling rates. The video converter for the system includes circuits for changing the display format to produce "zoom" enlargements and wide screen display suitable for racetrack applications.

Abstract: A video display system is disclosed. Video signals are converted from analog to digital format. Portions of the signal are selected for display and transmitted to the display elements. A high speed quality display is obtained by utilizing transmission circuits which can operate in real time at a rate sufficiently high to keep up with the incoming video signal. This permits the system to utilize more video information than it has previously been possible to use. An additional feature of the invention is the ability to simulate a travelling sign display by causing a message to appear to move across the scoreboard.
