Abstract
A wireless base station architecture that is particularly well-suited for providing audio, video and data services. An exemplary embodiment preferably transmits to all of an area those "common services" (e.g., broadcast television) that are intended to be received by multiple recipients throughout the area, but, in contrast, transmits only into a sector those recipient-specific services (e.g., point-to-point voice services, interactive video services) that are intended for less than all of the recipients in the area. In an exemplary embodiment, a demultiplexor directs both broadcast video and recipient-specific or "sectorized" video signals to a video processor, which prepares them for transmission. The demultiplexor also directs sectorized audio signals to an audio processor/RF combiner, which prepares them for transmission. The video processor preferably directs the broadcast video signals to an antenna, which radiates the signal throughout the area, but directs the sectorized video signals to the audio processor/RF combiner. The audio processor/RF combiner combines the sectorized audio signals and the sectorized video signals before transmitting them to an antenna, which radiate…
