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.

High speed video display system including zoom feature

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 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 utilized to store the digital representation of the video image in memory so that on line or off line presentations can be made.

A large display system capable of displaying a color 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.
