Abstract: A method of securely receiving data on a user's system from a web broadcast infrastructure with a plurality of channels. The method comprising receiving promotional metadata from a first web broadcast channel, the promotional metadata related to data available for reception; assembling at least part of the promotional metadata into a promotional offering for review by a user; selecting by a user, data to be received related to the promotional metadata; receiving data from a second web broadcast channel, the data selected from the promotional metadata, and wherein the data has been previously encrypted using a first encrypting key; and receiving the first decrypting key via a computer readable medium, the first decrypting key for decrypting at least some of the data received via the second web broadcast channel. In another embodiment, a method and system to transmit data securely from a web broadcast center is disclosed.

Abstract: A method, a system and computer readable medium of securely receiving data on a user's system from a web broadcast infrastructure with a plurality of channels. The method includes encrypting the data using a first encrypting key, wherein the first encrypting key is self-contained with all the information necessary to decrypt the data encrypted with the first encrypting key and encrypting the first decrypting key, using a second encrypting key. Next promotional metadata related to at least part of the encrypted data on a first web broadcast channel for reception by at least one user's system is broadcasted. Broadcasting at least part of the encrypted data over a second broadcast channel and transferring the encrypted first decrypting key, which has been encrypted with the second encrypting key, to the user's system via a computer readable medium.

Abstract: A method of securely providing data to a user's system over a broadcast infrastructure. The method comprising the steps of: encrypting the data using a first encrypting key; encrypting a first decrypting key using a second encrypting key; dividing at least part of the encrypted data into a series of logical packages; placing at least some of the logical packages into a broadcast carousel for cyclical broadcast over the broadcast infrastructure; broadcasting the packages in broadcast carousel so that they can be received by at least one user's system, wherein the broadcast is cyclical and repeats periodically; and transferring the encrypted first decrypting key, which has been encrypted with the second encrypting key, to the user's system. In another embodiment, a system is disclosed to carry out the above method in a broadcast infrastructure and an image overlaid on top of a primary image being displayed isused to denote that additional logical packages are available for receipt by broadcast.

Abstract: A method for receiving digital content data on a user's system for playing or recording, the content data being compressed and encrypted with a first encrypting key, said method comprising the steps of: tuning a receiver to a selected frequency; receiving content data through a broadcast transmission at the selected frequency; assembling the content data that is received; and transferring the content data to a player for playing the content data after all the content data has been received. In accordance with another embodiment of the present invention, an information processing system and computer readable medium is disclosed for carrying out the above method.
