Filed: 1999-04-01
Abstract: A novel multiple channel architecture (265) is designed to allow targeted advertising directed to television terminals (220) connected to an operations center (202) or a cable headend (208). Program channels carry television programs. The invention uses upstream data reception hardware (262, 275, 297), databases (301) and processing hardware (285, 293) and software to accomplish these functions. During commercial breaks in the television programs, advertisements, which are also broadcast on the program channel, are displayed. However, additional feeder channels carry alternate advertising that may be better suited for certain viewing audiences. The operations center (202) or the cable headend (208) generate a group assignment plan (293, 299) that assigns the television terminals (220) to groups, based on factors such as area of dominant influence and household income. A switching plan (291) is then generated that instructs the television terminals (220) to remain with the program channel or to switch to one of the altemate feeder channels during the program breaks. The television terminals (220) record which channels were viewed during the program breaks, and report this information to the cable headend (208) and the operations center (202). The reported information is used to generate billing for commercial advertisers, and to analyze viewer watching habits.
