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.

Service gateway for interactive television

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. SGW enables SP clients at STBs utilizing DATP to communicate with service applications using a variety of communication protocols. A content converter is provided to convert standard Web content into content suitable for display on a client-viewing device, e.g., a TV.

Digital television application protocol for interactive television

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. The invention further comprises a method for measuring audience behavior and response to particular events or programs and advertisements; and a method for adaptive delivery of advertisements to a client. Advertisements are scheduled according to an agreement and manifested into campaign rules and desired run times. A profile of a viewer that resides on the client device is used as the criteria for selection of a particular advertisement from a broadcast and for polling of audience viewing habits. The present invention further monitors the integrity and connectivity of the interactive television network and service providers.
