System and method of selective advertising on a TV channel

摘要

A method and system for providing selective advertising on a television channel is accomplished by downloading appropriate advertisements from an advertising server to a subscriber's set top box over an out-of-band channel. The set top box monitors for events. When an event occurs, the set top box signals the head-end to download ads to the set top box. The ads may be selected using demographic or common channel preference pattern information associated with the set top box.
