摘要： Within a desired service area, multiple transmitters (TX) at separately located sites simultaneously broadcast the same multi-channel, multi-program signal. Broadcast waves from the transmitters (TX) propagate throughout substantially overlapping portions of the service area. At most receiving sites, the receiving antenna can receive a clear line-of-sight transmission from at least one and often two or more of the transmitters (TX). Each broadcast channel carries a multiplexed digital data stream containing packets of information for a plurality of programs, e.g. TV programs. A shared antenna system, typically including multiple receiving antenna (31) aimed at a plurality of the transmitters (TX), supplies received signals to terminals (100) in a plurality of living units (75). The shared receiving system distributes selected channels of digitized data to terminals in different living units via the telephone wiring for those units. The shared system also provides an interface (32) to a broadband landline network carrying broadcast channels with multiplexed transport streams formatted in essentially the same manner as the wireless broadcast information. The shared system can selectively supply RF broadcast streams from the landline network over the telephone wiring to the living units, in the same manner as for the wireless transmissions.

摘要： 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. The control processor executes the software received and stored in the memory to control subsequent operations of the terminal, including at least some operations of the audio/video processor and at least some responses to user inputs.

摘要： A cellular system for distributing a plurality of television programs ("VIDEO PROGRAMS") in a desired service area. A plurality of groups of spaced transmitting antennas (TX1-TXN) are disposed substantially on the peripheries of adjacent cells disposed in the service area. The antennas (TX1-TXN) are directional and each is directed so as to propagate substantially the same simulcast signal into a respective cell so that propagation patterns of the antennas associated each cell overlap. In a broadcast embodiment, the frequencies of the signals transmitted by all antennas are the same. In a dedicated service embodiment, the frequencies transmitted into adjacent cells are different. In said broadcast embodiment, an omni-directional antenna may be placed in a centrally located disposition in the overall service area. The signals are broadcast (171-17N) as spread spectrum signals and provisions may be made for increasing the transmitted power. The receivers include despreaders wiht Rake capabilities.

摘要： Within a desired service area, multiple transmitters (TX1-N) at separately located sites broadcast the same multi-channel, multi-program digital video signal. Broadcast waves from the transmitters (TX1-N) 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 (TX1-N) at certain receiving sites. However, at most receiving sites, the receiving antenna (31) can receive a clear-line-of-sight transmission from one of the transmitters (TX1-N) via a directional antenna having a narrow field of view. Some receiving antennae will receive direct transmissions from at least one of the transmitters (TX1-N). 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 (TX1-N). In the preferred implementation, the channels are 6MHz wide channels broadcast in the upper high-frequency microwave portion of the spectrum. Each such channel carries a mutiplexed digital data stream containing packets of information for a plurality of programs, e.g. TV programs.

摘要： 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 (1 and 2), MMDS (E1-F4) and ITFS (A1-D4) licenses for microwave video channels in the high end of the UHF frequency range. Once rights to use the channels have been acquired, a digital multiplexing system (10), including multiplexers (12), modulators (13), and RF combiner (15), 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.
摘要翻译：通过用数字多路复用业务代替模拟业务来升级RF广播频道的节目传输容量。 RF信道可以从一个或多个方获得，例如，在UHF频段高端的微波视频通道持有MDS（1和2），MMDS（E1-F4）和ITFS（A1-D4）许可证的各方。一旦获得使用频道的权利，就部署了包括多路复用器（12），调制器（13）和RF组合器（15）的数字多路复用系统（10），用于在每个可用的RF广播频道上广播数字传输流。对于通过一个通道提供模拟服务的许可证持有者，一个通道的数字传输流将包括代表该程序服务的信息的压缩数字数据。因此，提供商可以利用这种运输能力继续提供现有服务。该频道的广播传输流还包括表示一个或多个新节目服务的压缩数字数据。
