Abstract

A system and method for storing and retrieving program material for subsequent replay is disclosed. The method includes accepting a receiver ID associated with a receiver key stored in a memory of the receiver, determining a pairing key for encrypting communications between the conditional access module and the receiver, encrypting the pairing key with the receiver key, and transmitting a message comprising the encrypted pairing key to the receiver. The apparatus comprises a receiver for receiving a data stream transmitting a media program encrypted according to a media encryption key and an encrypted media encryption key and a conditional access module, communicatively coupleable with the receiver.
