System and method for verifying content displayed on an electronic visual display

A system for verifying display of visual content on an electronic visual display, said system comprising:

• means for converting a digital verification code signal to a visual verification code signal, the digital verification code signal being representative of a verification code associated with the visual content;
• means for displaying the visual verification code signal in relation to the visual content signal on the electronic visual display;
• means for sensing the visual verification code signal as displayed by the electronic visual display;
• means for determining, based on the sensed visual verification code signal, the verification code as displayed in the visual verification code signal;
• means for generating a timestamp that indicates time of day that the visual content signal is displayed;
• and
• means for verifying that the visual content was timely displayed based on the determination of the verification code and generated timestamp.

A computer-readable storage medium having stored thereon sequences of instructions, the sequences of instructions including instructions, when executed by a processor, causes the processor to:

• convert a digital verification code signal to a visual verification code signal, the digital verification code signal being representative of a verification code associated with a visual content signal;
• display the visual verification code signal in relation to the visual content signal on the electronic visual display;
• measure the visual verification code signal as displayed by the electronic visual display and sensed by an optical sensor;
• determine the verification code as displayed in the visual verification code signal based on the measured visual verification code signal;
• generate a timestamp that indicates time of day that the visual content signal is displayed;
• and
• verify that the visual content was timely displayed based on the determination of the verification code and generated timestamp.

A method for verifying output of sensory content by an electronic device, said method comprising:

• converting a digital verification code signal to a sensory verification code signal, the digital verification code signal being representative of a verification code associated with a sensory content;
• outputting the sensory verification code signal in relation to a sensory content signal representative of the sensory content on the electronic device;
• sensing the sensory verification code signal as output by the electronic device;
• based on the sensed sensory verification code signal, determining the verification code as output in the sensory verification code signal;
• generating a timestamp that indicates time of day that the sensory content signal is output;
• and
• verifying that the sensory content signal was timely output based on the determination of the verification code and generated timestamp.

A method for verifying display of visual content displayed on an electronic visual display, said method comprising:

• forming a verification code including alphanumeric information that identifies the visual content;
• converting a digital verification code signal to a visual verification code signal, the digital verification code signal being representative of the verification code associated with the visual content;
• displaying the visual verification code signal with a visual content signal representative of the visual content on the electronic visual display;
• sensing the visual verification code signal as displayed by the electronic visual display;
• and
• verifying that the visual content was displayed based on the sensed visual verification code signal.

A method for verifying display of visual content displayed on an electronic visual display, said method comprising:

• converting a digital verification code signal to a visual verification code signal, the digital verification code signal being representative of a verification code that identifies the visual content and including data to cause the visual verification code signal to be displayed in at least one predetermined color;
• displaying the visual verification code signal with a visual content signal representative of the visual content on the electronic visual display in the at least one predetermined color;
• sensing the visual verification code signal as displayed by the electronic visual display;
• and
• verifying that the visual content was displayed and displayed with correct colors based on the sensed visual verification code signal.
