Latest Patents

One of Darr's latest patents focuses on downloading application software through a broadcast channel. Set-top terminals utilized in broadband broadcast networks are becoming increasingly intelligent and programmable. However, transmitting executable code, data, and interactive audio/video materials through a selectively dedicated link requires an extensive, broadband point-to-point network, which can be prohibitively expensive for large numbers of customers. Darr's invention provides a solution by allowing the downloading of application software and transmitting audio/video information through a single channel of a digital broadcast network. This network also supports two-way, low-speed data communications for signaling and interactive text services. The signaling via data communication with a text server controls the downloading of executable code from the digital broadcast channel into a programmable digital set-top terminal. The execution of the downloaded code enables selective capture and presentation of audio and video segments received over the digital broadcast channels. The resident operating system and application software in the terminal facilitate all communication with nodes of the network. The downloaded code forms a non-resident application with a set of predetermined function calls for activating communication functions of the resident software.
