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.

Abstract: The present invention is a Web based operating system that provides general access to resources distributed throughout the Internet. It provides a graphical user interface through which users may perform common “desktop” operations, such as invoking applications, copying files, and setting sharing attributes of files, and translate them to the operations that are appropriate for the resources that are the target of the request. Additionally, the invention provides a general-purpose attribute store or registry to keep the persistent state needed by the WebTop and other applications, including users preferences, application-invocation information, and application settings and any other attribute-type information.
