Abstract
An apparatus for providing local programming with direct broadcast satellite transmissions includes a terrestrial transmitter for transmitting converted local channel signals in a first frequency band. The first frequency band is contained within a satellite broadcast frequency band in which the direct broadcast satellite channels are transmitted. The apparatus also includes at each user or subscriber location, a first antenna for receiving the converted local channel signals from the terrestrial transmitter and a second antenna for receiving a direct broadcast satellite channel signals from the satellite. The apparatus further includes a combiner for combining the converted local channel signals and the direct broadcast satellite channel signals on a single propagation path. A signal processor/decoder processes the combined signals on the single propagation path to produce a desired channel output to drive a television set. To the processor/decoder the combined channel signal appears as if it had been all broadcast directly from the satellite. Therefore, the apparatus requires no additional receiver for receiving local programming along with regional and national programming provided by satellite transmission.
