摘要:
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.
