A system and method for the retrieval and transfer of encrypted content from a failed set-top box by a content transcription device. When content is recorded to the storage device of a set-top box, the content is encrypted with a content instance key. This content instance key is encrypted with the public key of the set-top box and a duplicate of the content instance key is encrypted by another public key other than the public key of the set-top. In the event the set-top fails, the encrypted content on the storage device may be retrieved from the storage device by decrypting the duplicate content instance key with the private key that corresponds with the public key that encrypted the duplicate of the content instance key.
The present U.S. application is a divisional of copending U.S. patent application Ser. No. 10/920,926, filed on Aug. 18, 2004, entitled “RETRIEVAL AND TRANSFER OF ENCRYPTED HARD DRIVE CONTENT FROM DVR SET TOP BOXES,” which is related to U.S. application entitled “RETRIEVAL AND TRANSFER OF ENCRYPTED HARD DRIVE CONTENT FROM DVR SET-TOP BOX UTILIZING SECOND DVR SET-TOP BOX” and to U.S. application entitled “UTILIZATION OF ENCRYPTED HARD DRIVE CONTENT BY ONE DVR SET-TOP BOX WHEN RECORDED BY ANOTHER”, to the same inventor, which are incorporated herein by reference.
The present invention relates to the field of set-top terminals and, more particularly, relates to the storage, recovery and transfer of encrypted content from a storage device for reuse without utilizing the original secure microprocessor.
20. The method of claim 13, wherein the encrypted copy of the at least one access rights element is a copy of a first digital rights element defining first access rights to at least the television program instance for a particular user, and the storage device includes a second access rights element defining second access rights to at least the television program instance for the particular user, and the first access rights are different from the second access rights.
