Abstract
A method of diagnosing connectivity and operational problems between a digital parallel RGB video input device and a digital parallel RGB video display includes transmitting control signals from the input device to the display device, executing the control signals on the display device, generating and transmitting diagnostic signals to a diagnostics processor, and determining if the display is functioning correctly.
Claims20
A method for diagnosis connectivity and operation of a digital RGB video display, comprising:
- transmitting video control and data signals from a video input device to an RGB video display;
- executing the control and data signals on the RGB video display;
- generating at the RGB video display a diagnostic signal corresponding to each executed control and data signal;
- transmitting the diagnostic signals to a diagnostics processor;
- determining using the diagnostic processor whether each of the diagnostic signals is indicative of a correctly executed control or data signal;
- and
- taking corrective action when a diagnostic signal indicates that a corresponding video control or data signal was not received or not properly executed by the RGB video display.
4 more elements
An RGB video display system having connectivity and operational diagnostic capabilities, comprising:
- a video input device configured to transmit RGB video control and data signals;
- an RGB video display adapted to receive and execute video control and data signals;
- signal conductors for transmitting video control signals from the video input device to the video display;
- a diagnostics processor;
- signal conductors for transmitting diagnostics signals from the RGB video display to diagnostics processor;
- and
- wherein the diagnostics processor is configured to determine whether each of the diagnostic signals is indicative of a correctly executed video control or data signal.
