Patent ID: 7567671

Claim:
A method to securely distribute media content with associated media information as part of a media package in a media distribution system, the method comprising the steps of: a) encrypting the media content prior to distribution and storing it as part of the media package so that it can be decrypted using a program key; b) encrypting the program key using a first set of local hardware identifiers available on a first digital system and creating local decryption information that is used with the first set of local hardware identifiers to decrypt the encrypted program key; c) storing the locally encrypted program key and local decryption information in the media package; d) transferring the media package to an e-PVR in a second digital system with a second set of local hardware identifiers when presentation of the media content is requested by a user; e) attempting to decrypt the locally encrypted program key using the local decryption information and the second set of local hardware identifiers; and f) failing to decrypt the locally encrypted program key when first and second set of local identifiers is not the same and the first and second digital system is not the same, and succeeding when the first and second digital system is the same and the first and second hardware identifiers are the same, and when successful presenting the media content.
