Abstract
An electronic redeemable coupon generating system includes: an encoder for encoding coupon-related data in a television signal transmission, the transmission including picture information for display on a television monitor screen; a decoder for receiving the television signal transmission and extracting the coupon-related data therefrom; and a recording device for recording the extracted coupon-related data on a recording medium for subsequent readout and redemption. In a preferred embodiment of the invention, the decoder includes a display driver for displaying indicia on a television monitor screen responsive to coupon-related data being encoded in the television signal transmission. Upon observing the indicia on the television monitor screen, the user can manually and selectively extract the coupon-related data from the television signal transmission. After an optional editing function, the extracted coupon-related data is stored on a recording medium such as a magnetically striped card. The decoder may be part of the standard circuitry of a closed-caption adapted or modified television set. Provisions are made for electronically entering paper coupon information into the syste…
