TELEVISION DISTRIBUTION SYSTEM AND METHOD

摘要

A transmission system is described which includes multiple transmitters (TX1, TXN) at separately located cites simultaneously broadcast the same multi-channel, multi-program signal throughout a desired service area. Broadcast waves from the transmitters (TX1, TXN) propagate 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.
