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.
