摘要： 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.

摘要： 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.

摘要： 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.
