A high resolution video display system suitable for use in displaying large outdoor scoreboards is disclosed. Video signals are converted from analog to digital format. Portions of the signal are selected for display on the scoreboard and the selected portions are then processed and transmitted to the scoreboard elements. A high resolution display is obtained by utilizing quantizing, selection, and 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 traveling sign display by causing a message to appear to move across the scoreboard.

High resolution video display system

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 analogue to digital format and is directly loaded into a display memory (RAM). The digitized data is 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 displays suitable for racetrack applications.
