Patent ID: 7336784

Claim:
An audio/video distribution system with enhanced digital rights management configured for use with a source of programming, the system comprising: a source encryptor for transmitting the programming in encrypted form with missing content such that even if the programming is hacked, the programming is not usable, wherein the encrypted programming is wrapped in a time envelop based upon a signal generated by an atomic clock at a time of said transmitting the programming and includes applicable policies, rights and/or rules associated therewith to the recipient location; an authentication device at the recipient location to interact with a third party responsible for authorization of accessing the programming; and a receiver at the recipient location, the receiver including: an input for receiving the programming, an encryptor for encrypting again the programming so that the programming is unique to the receiver, a decryptor, an output for delivering the programming to the audio/video output device, a bi-directional link for communicating with a third party authenticator, a sensor for receiving a programming request from the authentication device, and a processor operative to: a) send a signal to the third party in response to the programming request, b) cause the decryptor to add the missing content while decrypting the programming in response to an authorization signal from the third party, wherein the decryptor succeeds only at a specific time specified in the time envelop such that an attempted unauthorized decryption at a later time would not be possible, c) cause the decryptor to control the usage in accordance with the policies, rights or rules, and d) output the programming to the audio/video output device.
