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. The audio/video processor converts compressed, digital information received over the broadband channel into signals for driving an audio/video display device, such as a standard television set.

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. Resident operating system and application software in the terminal provides all communication with nodes of the network.

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. When a user presses a GUIDE button on a remote control service, the DET displays the available information service providers in accordance with the VIP program map, thereby enabling the user to conveniently access the broadband services offered by the selected information service provider.

This invention relates to a catalyst containing palladium and optionally chromium on an alumina which is used for the selective hydrogenation of acetylenic hydrocarbons in olefin gas streams. The catalyst is characterized by the use of an alumina support having a surface area of less than about 5 square meters per gram, a Hg pore volume of between about 0. 2 and about 0. 5 cubic centimeters per gram and wherein at least 40% of the pore volume is contained in pores having pore diameters of greater than about 10 microns.

An improvement on a process for decreasing the total sulfur content of off-gases from a Claus process is described wherein the sulfur dioxide-containing off-gas is mixed with a reducing gas and passed over a metallic reduction catalyst at elevated temperature to reduce the sulfur dioxide and other convertible sulfur compounds present to hydrogen sulfide followed by cooling of the thusly reduced gas stream at least partially by direct cooling with an aqueous quench liquid and removal of the hydrogen sulfide from the cooled gaseous stream by adsorption on an absorbent or absorbent for hydrogen sulfide, in which process the flow of either or both of the sulfur dioxide containing off-gas and the reducing gas to catalytic reduction is controlled by monitoring the sulfur dioxide content of the reduced gas stream. The improvement comprises monitoring the sulfur dioxide content of the reduced gas stream by subjecting a portion of the liquid quench streams utilized to cool the hydrogen sulfide-containing gas stream from catalyst reduction to stripping with an inert gas thereby substantially removing the hydrogen sulfide and carbon dioxide contained in said quench liquid and measuring the pH of the stripped quench liquid.

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. If the broadcast version number differs from the version number for the operating system the terminal currently is running, then the terminal will capture only the file containing the operating system for the corresponding terminal type.
