Abstract: Delivery of audiovisual data may be accomplished using a satellite system. The user may have a set-top box connected to a satellite dish and a network connection. An operator server may receive a request for a title from the user via the network connection. The operator server may then determine if the title is in a transmission schedule and add it to the schedule if it is not. The data corresponding to the request may be encrypted using an encryption algorithm, and a corresponding decryption key may be generated. The key may then be forwarded to the user via the network connection. Then, according to the transmission schedule, the database containing the data will forward the data to a transmitter where it is communicated to a satellite in orbit, which then communicates the data to the satellite dish. The data may be stored in the set-top box for later playback.

Abstract: A specially designed system for E-Business and for access to sources (goods, services and information) is provided which is based on an enclosed network environment comprising a group of servers connected to an independent network with established and secured communication with the surroundings. This ensures that clients are properly mediated and secured access is available via the interface. The interface is the place where all internal services are provided to the Client. The system ensures transparent and safe implementation of Internet business, quick and easy acquisition of any kind of information whatsoever (data) from electronic sources without the need for special knowledge or skills (knowledge of electronic addresses, ability to control searching servers, etc.), and guarantees the observance of license agreements and protection of copyright, allows mass dissemination of the use of electronic trade by user groups who do not possess special knowledge.

Abstract: A method of utilization of an E-Business system solution and of access to information sources is provided which identifies a client and a source and distributes the data stream on demand. Both analog and digital data may be used by the system. The proposed solution is based on the identification of a client after his entry to the system. Upon receipt of a data stream demand from the Client, the system identifies the required data source and at the same time it sets up a secured transfer channel together with performing data stream distribution process optimizing. The system also may reserve for the client a channel for optional feedback. The data sources are the providers and/or distributors of services, information, or goods. The method of sale or distribution is then ensured by the data stream transfer.
