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 throughout substantially overlapping portions of the service area. Each broadcast channel carries a multiplexed digital data stream containing packets of information for a plurality of programs, e.g. television programs. A shared antenna system, typically including multiple receiving antennae aimed at a plurality of the transmitters, supplies received signals to terminals in a plurality of living units. The shared system includes delayed signal processing circuitry to supply an optimal signal from the receiving antennae to the terminals. The delayed signal processing circuitry has a processing time window of a predetermined value at least as large as the difference in arrival time of signals propagating to the shared system from the nearest and farthest transmitters from which the shared system receives direct transmissions.
