Television distribution system and method |
摘要 |
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.
