Abstract
Systems, devices and automated processes detect piracy of broadcast television signals through selective delay of decrypted code words that are used to render satellite or other received television signals. Smart cards or similar access control hardware are programmed to selectively delay delivery of cryptographic code words based upon the identity of the receiver device. The delayed delivery of the code words produces intentional glitches in the content rendered by the receiver, thereby allowing viewers of the rendered content to ascertain the identity of the device.
