Patent AT-E401740-T1: [Translated] SECURE RECORDING AND PLAYBACK OF MEDIA PROGRAMS USING MUTUALLY MATCHED RECEIVER AND STORAGE DEVICE
A method and apparatus for storing and retrieving program material for subsequent replay is disclosed. The method comprises the steps of receiving a data stream comprising the program material encrypted according to a first (CW) encryption key, decrypting the program material; re-encrypting the program material according to a second encryption key (516); and storing the re-encrypted material in a media storage device (528). The program material is played back by retrieving the re-encrypted material (518) from the media storage device (528) and decrypting the re-encrypted program material. In one embodiment, the second encryption key (516) is derived from metadata describing replay rights. In a further embodiment, the media storage device (528) also stores the second encryption key (516) which has been further encrypted by a key (520) that is unique to the device used to receive the program material.
