Abstract
A system and method for providing multiple levels of verification of displaying visual content on an electronic visual display. One embodiment includes a method that displays a visual verification code signal in relation to a visual content signal representative of the visual content displayed on the electronic visual display. The visual verification code signal is sensed as displayed by the electronic visual display, and, based thereon, the verification code is determined and verification of the display of the visual content on the electronic visual display is performed. The visual verification code signal may be displayed in different colors to verify the operation of the electronic visual display with respect to color and intensity.
