Abstract: To provide interactivity, a public wireless packet data network is combined with a broadband digital broadcast network. In the preferred embodiment, the broadcast network utilizes multiple transmitters at separately located sites simultaneously broadcasting the same multi-channel, multi-program signal. Broadcast waves from the transmitters propagate throughout substantially overlapping portions of the service area. Customer premises receiving systems include a receiving antenna and one or more digital entertainment terminals. The terminal includes a channel selector and digital receiver for capturing a digital transport stream from a selected channel. A processor converts selected program information from the transport stream for presentation, e.g. via a television set. The terminal also includes a CPU controlling the operation of the channel selector and the processor in response to user inputs.

Abstract: Within a desired service area, multiple transmitters at separately located sites simultaneously broadcast the same multi-channel, multi-program signal. Broadcast waves from the transmitters propagate substantially throughout the service area and overlap in a substantial portion of the area. The signals are broadcast as spread spectrum signals and the receivers include despreaders with rake capabilities to obtain enhanced output signals with multi-path reception. In the preferred implementation, the channels are 6 MHz wide channels broadcast in the super high frequency microwave portion of the spectrum. Each such channel carries a multiplexed digital data stream containing packets of information for a plurality of programs, e.g., television programs.

Abstract: An arrangement (apparatus and method) for obtaining a single copy of a received signal from a simulcast broadcast area. Within a desired service area, multiple transmitters at separately located sites simultaneously broadcast the same multi-channel, multi-program signal. Broadcast waves from the transmitters propagate throughout substantially overlapping portions of the service area. Each such channel carries a multiplexed digital data stream containing packets of information for a plurality of programs, e.g. television programs. A receiver system comprises an antenna adapted to receive direct transmissions from two or more of the transmitters as well as multipath signals from two or more of the transmitters. To compensate for the potentially interfering signal receptions, the terminal device includes a delay processor, such as an adaptive delay equalizer or a rake receiver.

Abstract: A control node, such as a services control point, of an intelligent telephone network interfaces to a wireless broadband network for signaling communications with broadband terminals. In normal operation, the terminals present video or other broadband information carried on the wireless network, typically via an associated television set. During processing of a telephone call, a central office switching system of the telephone network will recognize a predetermined event in call processing which triggers a query to the control node. Ultimately, the control node will return an instruction to the switching system to continue call processing. However, as part of its own processing, the control node sends a message through the broadband network to the broadband terminal of the subscriber to which the telephone call relates. If operational, the terminal may display call related information contained in the message, e.g. Caller ID information for an incoming call.

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: A cellular system for distributing a plurality of television programs in a desired service area. A plurality of groups of spaced transmitting antennas are disposed substantially on the peripheries of adjacent cells disposed in the service area. The antennas are directional and directed to propagate substantially simulcast signals into the cell with which the antenna is associated so that the propagation patterns of the transmitting antennas associated with the cell overlaps over substantially a major portion of the area enclosed within the cell. Antennas disposed substantially on the peripheries of adjacent cells propagate directional signals into each of the adjacent cells. In a broadcast version the frequencies of the signals transmitted by all of the antennas are the same. In a dedicated service version the frequencies of the signals transmitted into adjacent cells are different.

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.

Abstract: The program transport capacity of an RF broadcast channel is upgraded by replacing analog services with digitally multiplexed services. RF channels can be obtained from one or more parties, e.g. parties holding MDS, MMDS and ITFS licenses for microwave video channels in the high end of the UHF frequency range. Once rights to use the channel have been acquired, a digital multiplexing system is deployed for broadcasting a digital transport stream over each available RF broadcast channel. For license holders who offered an analog service over one channel, the digital transport stream for one channel will include compressed digital data representing information from that program service. The provider therefore can use this transport capacity to continue to offer the existing service. The broadcast transport stream for that channel also includes compressed digital data representing one or more new program services.

Abstract: Within a desired service area, multiple transmitters at separately located sites broadcast the same multi-channel, multi-program digital video signal. Broadcast waves from the transmitters propagate throughout substantially overlapping portions of the service area. Obstructions in the service area, e.g. mountains, buildings, trees, etc., may block reception from one or more of the transmitters at certain receiving sites. However, at most receiving sites, the receiving antenna can receive a clear line-of-sight transmission from one of the transmitters via a directional antenna having a narrow field of view. Some receiving antennae will receive direct transmissions from at least to of the transmitters. To compensate for differences in propagation time to such receiving antennae, time delays of predetermined amounts are imposed between broadcasts by two or more of the respective transmitters.
