Abstract

Coupon information is stored in a memory at a cable television station. The cable television station may simultaneously transmit multiple video signals, each representing different sources of television programming, over multiple television channels on the cable network. The video signal may at times, such as during a product advertisement or other offer, include an embedded coupon identifier. A coupon subsystem at the cable television station monitors each video signal and retrieves token information from a database when it detects a corresponding embedded token identifier. The coupon information is transmitted over a data channel on the cable network. A subscriber unit at the television viewer's site receives the data channel and extracts the coupon information. The television programming aurally or visually alerts the viewer that a coupon may be generated. If the viewer actuates an input device, such as a button on a television remote control, a printer generates a coupon bearing the coupon information.
