ABSTRACT:
A method of revoking a descrambling privilege for copy controlled content to a host device is provided. The method includes receiving copy controlled content at a conditional access module. A revocation list is also received at the module. The method includes determining whether the host device associated with the module is on the list. If so, the conditional access module will not descramble the content.
