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.
