A multi-beam DBS satellite system capable of providing spectrally efficient
regional programming is disclosed. The inventive system includes at least
one DBS satellite having a repeater connected between multiple uplink
antennas and multiple downlink antennas. The repeater has a switching
processor and a formatting processor. The switching processor includes
circuitry for filtering individual channels of information from the uplink
frequency division multiplexed (FDM) beams received at the uplink
antennas, and also includes circuitry for switching the channels of
information to form a set of switched channels. These switched channels
are then combined and routed to the formatting processor. The formatting
processor converts the switched FDM information into a combined digital
TDM signal that preferably corresponds to the DVB standard. Using this
repeater, the present invention is capable of linking different
geographical sources of programming information to multiple downlink beams
in a flexible and spectrally efficient manner for direct transmission to
home receivers.
