DISPLAY GENERATION SYSTEM
First Claim
1. A display generation system for connection to an aircraft display, the display generation system comprising:
- a processing engine configured to generate display signals for at least one first image, to one of generate and receive display signals for at least one second image, and to provide display signals for at least the at least one first image to the aircraft display; and
an error detection system configured to perform error detection processing to detect whether at least one of the display signals for the at least one first image and the display signals for the at least one second image includes a graphical error and to generate at least one processing result indicating whether the error detection system detected a graphical error;
wherein the processing engine is further configured to receive the processing result and discontinue the generation of at least the display signals for the at least one first image when the at least one processing result indicates the occurrence of a graphical error.

Abstract
A display generation system that is able to generate display signals for an underlay image with at least one embedded safety pattern and display images for an overlay image. The display generation system and method are able to determine whether there are any anomalies or graphical errors when an overlay display generated by the system or generated by some other system is displayed simultaneously with the underlay image with the embedded safety pattern. The display generation system uses the embedded safety pattern to detect the occurrence of anomalies in the simultaneous display and uses information from its own generated overlay image to detect graphical errors in the simultaneous display. Flight display systems for aircraft can use the display generation system and method of the present invention to display an underlay image depicting geographical scenery in the vicinity of the aircraft while on the ground, during takeoff or in flight. The underlay image is displayed simultaneously with an overlay image depicting standard graphics of a flight display system.

10. A method for displaying images on an aircraft display comprising steps of:
-
generating display signals for at least one first image; one of generating and receiving display signals for at least one second image; providing display signals for the at least one first image to the aircraft display; generating at least one processing result indicating whether a graphical error occurred; and discontinuing the generation of at least the display signals for the at least one first image when the at least one processing result indicates that a graphical error occurred. - View Dependent Claims (11, 12, 13, 14, 15)
