Abstract: Set-top terminals utilized in broadband broadcast networks are becoming increasingly intelligent (programmable). However, transmitting executable code, data and interactive audio/video materials through a selectively dedicated link requires an extensive, broadband point-to-point broadband network, which is prohibitively expensive to implement for large numbers of customers. The present invention provides for downloading application software and transmitting audio/video information through one channel of a digital broadcast network. The network also provides two-way, low-speed data communications capacity, e.g. for signaling and/or interactive text services. Signaling via data communication with a text server controls downloading of executable code from the digital broadcast channel into a programmable digital set-top terminal. Execution of the downloaded code in turn controls selective capture and presentation of audio and video segments received over one of the digital broadcast channels.

Abstract: Dynamic programming of a digital entertainment terminal (DET) facilitates operation of the terminal to offer a variety of functionally different broadband services. The terminal includes a network interface module which couples the terminal to a specific type of communication network for receiving a digital broadband channel. The DET downloads on a narrowband signaling channel a VIP program map that identifies the available video information service providers (VIPs) on the basis of the location of their corresponding software control signals. The software control signals are transmitted cyclically to enable access by a random DET at any time. A program memory captures the VIP program map and at least a portion of the software control signals received over the digital broadband channel as software executable by the control processor during turn-on of the DET.

Abstract: Set-top terminals utilized in broadband broadcast networks are becoming increasingly intelligent. Upgrading the operation of such terminals periodically requires upgrading the software, particularly the operating system, of the programmable processor which controls the terminal operation. To facilitate frequent upgrades, the network will carry a cyclic broadcast of a packetized data file containing the operating system. Periodically, a terminal will capture and store the broadcast operating system. In the preferred embodiment, the broadcast includes operating system files for a number of different terminal types and data identifying the current broadcast version of the operating system for each type of terminal. The terminal will check the broadcast version number for its terminal type operating system.

Abstract: Dynamic programming of a digital entertainment terminal (DET) facilitates operation of the terminal to offer a variety of functionally different broadband services. The terminal can be reprogrammed, as-needed, for each different service offered by one or more information service providers. The terminal includes a network interface module which couples the terminal to a specific type of communication network for receiving a digital broadband channel and providing two-way control signaling communication between the terminal and the network. The terminal also includes a control processor with a program memory. The control processor receives user inputs and controls operations of the terminal and sending and receiving of control signals over the two-way control signaling channel. The program memory stores data received over the digital broadband channel as software executable by the control processor.
