ABSTRACT:
A method and system for controlling unauthorized signal usage in a content delivery network, such as a television network, is described. The method and system acquires at least two signal usage records for a receiver of the content, evaluates the at least two signal usage records for indicia of usage of a combination of signals not normally authorized on the receiver, and detects unauthorized signal usage upon the at least two signal usage records being consistent with such indicia.
