Abstract: An inventive client/server system provides a platform for cable system operators to deliver a full range of sophisticated new products to cable television subscribers. Preferably a middleware solution, the information platform provides a flexible, versatile, and adaptable Internet-centric platform that network operators can use to deploy interactive television applications. The information platform mediates the communication between an abundance of Web-based content and the television set. Content and applications are written entirely in industry standard HTML and Java. Traditional television programming is integrated with Web content using TV-specific extensions to HTML and Java. Applications can be loaded from the network, from carousels, or from file systems, such as flash memory or EEPROM. The information platform consists of client-side middleware integrated with a native electronic program guide application.

Abstract: Systems and methods are described for preparing multimedia data using digital video data compression. Various embodiments of the invention use pre-rendering and encoding techniques that format the video image data into fat macroblocks. The fat macroblocks include header information that identifies the beginning locations of strips of macroblocks representing slices of the image, and of the macroblocks disposed within the strips. The header information enables macroblocks disposed in a strip of fat macroblocks to be individually addressed thereby providing transmission bandwidth, data processing, and data storage advantages for preparing and transmitting data for updating video images including less than full screen motion. The advantages are achieved in part because updates only require that the first macroblock of each strip of macroblocks be transmitted.

Abstract: A store and forward (S&F) architecture is provided that supports multiple applications within an extensible network to direct information of various formats to any of multiple destinations. In the presently preferred embodiment of the invention, Java applications running on a client send non-priority data to any server on the application network or, alternatively, anywhere on a global telecommunications network such as the Internet, at some time in the future. In the preferred embodiment, S&F allows a client application to send usage statistics to a database on the application network. It also enables T-commerce purchases to be made by the user, where the purchase and other relevant information is sent to a destination web server as if the purchase had taken place on the web via a full web browser on an Internet-connected PC.
