Abstract

Decoding of data included in the vertical blanking interval of a television transmission signal and storage of the decoded data on a portable data coupon allows unavailable ease of use of commercial discounts, manufactures coupons, and other cost saving devices. The portable data coupon incorporates a receiver (16) for retransmitted encoded data and a storage device (36) for the received data. A display (22) for viewing the data is present in the storage device and a transmitting device (32) is incorporated for selectively transmitting portions of the encoded data for use such as in redeeming a coupon or discount. Selection of data received in the coupon from the VBI to be saved in storage for later redemption is accomplished through interactive input by the user and automatic timing for expiration of data and deletion of data upon redemption are also provided.
