1. A method comprising:
- optically receiving on a hand-held device a modulated video signal, the modulated video signal including auxiliary data modulated in an active portion of the modulated video signal;
detecting on the hand-held device the auxiliary data contained within the modulated video signal;
comparing the auxiliary data against prestored data on the hand-held device to determine whether a data match was identified;
enabling a prestored promotional opportunity within read only memory of the handheld device; and
sequentially illuminating a series of light-emitting devices on the hand-held device when the data match was identified to provide a representation of a value available for redemption by use of the hand-held device.

Abstract
A system for deriving benefits from the reception and processing of composite video signals by a hand-held device, such as a smart card. Video signals are modulated with auxiliary data creating composite video signals. The composite video signals are then transmitted to and received by a hand-held device. The auxiliary data is then detected in the modulated video signal by circuitry of the hand-held device. The user receives benefits resulting from the reception of the auxiliary data.

11. An interface card comprising:
-
a computer interface to transferring information to and receiving information from a computing device, the computing device being capable of detecting auxiliary data in a modulated video signal; a photodetector to optically receive the modulated video signal directly from a display device, the modulated video signal comprising a video signal modulated to contain the auxiliary data; a visual display; and a processor coupled to the computer interface, the photodetector, and the visual display and configured to; send the modulated video signal received through the photodetector through the computer interface to the computing device, receive the auxiliary data contained with the modulated video signal from the computing device, compare the auxiliary data against prestored data on the hand-held device to determine whether a data match was identified; enable a prestored promotional opportunity within read only memory of the handheld device; and present a value on the visual display when the data match was identified. - View Dependent Claims (12, 13, 14, 15, 16, 17, 18, 19)

20. A computer-readable medium encoded with computer readable instructions, which when executed by a machine, cause the machine to:
-
optically receive on a hand-held device a modulated video signal, the modulated video signal including auxiliary data modulated in an active portion of the modulated video signal; detect on the hand-held device the auxiliary data contained within the modulated video signal; compare the auxiliary data against prestored data on the hand-held device to determine whether a data match was identified; enable a prestored promotional opportunity within read only memory of the handheld device; and sequentially illuminate a series of light-emitting devices on the hand-held device when the data match was identified to provide a representation of a value available for redemption by use of the hand-held device.
