Abstract:
1. A method of providing conditional access to video content, the video content being encrypted by a second layer of encryption resulting in singly encrypted video content and the singly encrypted video content encrypted by a first layer of encryption resulting in multiply encrypted video, the method comprising: (a) receiving the multiply encrypted video content over a broadcast network by a subscriber's set top box without a user request; (b) receiving first decryption data with the multiply encrypted video content by the subscriber's set top box; (c) applying the first decryption data to the multiply encrypted video content by the subscriber's set top box to remove the first layer of encryption from the multiply encrypted video content to retrieve the singly encrypted video content; (d) preloading the subscriber's set top box with the singly encrypted video content for access at a later time; (e) transmitting a user request for viewing of the singly encrypted video content over the broadcast network from the subscriber's set top box; (f) receiving second decryption data over the broadcast network by the subscriber's set to box in response to the user request; and (g) applying the second decryption data to the stored singly encrypted video content by the subscriber's set top box to remove the second layer of encryption to retrieve the video content.
