Abstract: A service gateway provides a proxy between a client protocol and a plurality of standard communication protocols. The service gateway provides asymmetrical routing, data compression and encryption to optimize client processing power and communication link bandwidth. The service gateway enables content translation between clients and service providers. The service gateway keeps track of client available memory and sequence numbers in messages to generate error codes when applicable. A store and forward message capability is provided along with abstract session identifiers. The service gateway supports user datagram protocol.

Abstract: A common communication language that can address all the applications running in a multitude of set top boxes (STBs) or client devices and application servers. The present invention, DATP protocol encapsulates a Meta language that provides a generic portable communication application programmer interface that requires light processor utilization and is well suited for a typical STB possessing limited processing power. DATP requires relatively few processing cycles compared to typical Internet communication protocols. DATP reduces the overhead of the communication protocol handler at the STB and makes the communication protocol handler common for all STBs applications. The preferred DATP protocol is portable for all STBs since it is written in a native language that interfaces with the underlying operating system of the STB. A SGW (SGW) performs as a DATP server. The SGW translates between DATP messages and standard communication protocols.

Abstract: An encrypted private session key for a private-key encryption method is quickly exchanged between a first device and a second device by computing encryption acceleration data using a public key for a public-key encryption method. The encryption acceleration data and the public key are sent to and used on the second device to encrypt a private session key exchanged between the first device and second device. The private-key encryption method is quickly initialized on the second device using encryption initialization data for the private-key encryption method computed on the first device using the exchanged private session key sent to the second device. The encryption acceleration data and encryption initialization data reduce a number of calculations needed on the second device to initialize and use the private-key encryption method, thereby reducing the overall time needed to create a cryptographically secure communications channel between the first device and the second device.

Abstract: The present invention provides a method and apparatus for managing the presentation and regulation of E-Commerce, content and service providers access in an interactive television environment comprising interactions between a server, a client, and a service provider. Components are provided for managing and completing a purchase or delivery of an item offered by a service provider. A purchase transaction uses client information comprising partial client information from the client and a list of purchased items. Upon receiving partial information from the client, the server retrieves corresponding additional related information within its database and transmits this retrieved data from the server, along with the list of purchased items to complete the transaction. Business Agents are provided for logging the transaction, creating an electronic receipt, logging patches, logging error events, and viewer logging.
