Patent ID: 8406426

Claim:
At least one non-transitory computer-readable medium encoded with instructions which, when executed by processors of a first set top box and a second set top box, performs a method comprising: in the first set top box: encrypting content received and decrypted by the first set top box, the encrypting using a first cryptography key uniquely associated with the first set top box; storing the encrypted content on a digital storage medium; encrypting the first cryptography key using a second cryptography key that is stored in a secure protected storage location in the first set top box to form an encrypted first cryptography key; and storing the encrypted first cryptography key on the digital storage medium; in the second set top box, to which the digital storage medium has been installed after being removed from the first set top box: determining that the content is not encrypted using a cryptography key uniquely associated with the second set top box; sending a request to obtain the second cryptography key to a third party; and receiving and using the second cryptography key to decrypt the encrypted first cryptography key.
