Abstract
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 download triggers to provide advertisements to the subscriber's set top box and advertising triggers to insert advertisements when an advertising opportunity occurs. The advertisements can be downloaded in advance of any advertising triggers to a local storage means associated with the set top box, if available.
