Abstract
A method, apparatus, and article of manufacture provide the ability to activate functionality in a set-top box 500. A feature authorization message is received in a set-top box 500. The feature authorization message comprises one or more rules to be evaluated (wherein each of the rules comprises one or more tests for a status of one or more conditional access module 502 attributes), one or more event requirements for rule evaluation, and one or more features that are dependent by the rule evaluation result (wherein each of the one or more features represents a set of one or more abilities of hardware and/or software of the set-top box 500). When one or more of the event requirements have been met, the one or more rules are evaluated to obtain a result. The ability to use the one or more features are then set based on the result.
