Patent number: 6498922Abstract: 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.Type: GrantFiled: August 20, 1999Date of Patent: December 24, 2002Assignee: Com Dev LimitedInventors: Ken Lazaris-Brunner, Gary Beauchamp, Bharat Tailor

Patent number: 6408164Abstract: An analog processor for use with digital satellites is disclosed. The analog processor is connected between the receiving circuitry of the satellite and a pool of digital on-board processors, and segments the bandwidth of uplink RF beams into sub-bands that can be processed more readily with standard, low-risk, low-power digital processors. Using the present invention, the risk of employing a particular digital processor technology can be managed and optimized. The present invention also provides for the dynamic allocation and reallocation of the available on-board digital processing bandwidth based on the anticipated traffic pattern and changes in the traffic pattern. In addition, the present invention facilitates the use of standard and non-standard redundancy schemes at minimal hardware expense.Type: GrantFiled: June 9, 1999Date of Patent: June 18, 2002Assignee: Com Dev LimitedInventors: Ken Lazaris-Brunner, Gary Beauchamp, Bharat Tailor

Patent number: 5825325Abstract: An improved multi-beam bent-pipe communications satellite system and method includes a subchannel switching processor for extracting and switching subchannels of information to and from a plurality of uplink and downlink beams and an intersatellite link for routing certain of the extracted subchannels to another satellite in the system. The subchannel switching processor preferably employs a partial subchannelization processor that combines a coaxial switching network for switching some of the uplink channels at the channel level with an analog or digital transparent subchannel switching network connected to a portion of the uplink channels for extracting and switching at the subchannel level. The switched subchannels are combined to form channels, and then routed to either the downlink beams (where they are combined with other switched channels), or to the intersatellite link for transmission to another satellite.Type: GrantFiled: September 17, 1996Date of Patent: October 20, 1998Assignee: Com Dev LimitedInventors: Val O'Donovan, Gary Beauchamp, Robert Peach

Patent number: 5822312Abstract: A repeater for a multibeam communications satellite combines the features of coaxial channel interbeam switching and subchannelization of some of the channels. In one embodiment described, the input radio-frequency signals from the input beams are fed through the input multiplexers to form channels. Some, but not all, channels are subsequently subchannelized for interbeam switching. In another embodiment of the invention, a portion of the incoming radio frequency signals bypasses the input demultiplexer and is filtered for noise-limiting reasons, converted down to an intermediate frequency and then subchannelized using SAW filters. The specification also teaches that digital techniques can be used to obtain the same results.Type: GrantFiled: April 17, 1996Date of Patent: October 13, 1998Assignee: COM DEV LimitedInventors: Robert Peach, Nigel Miller, Bharat Tailor, Kamal Ali, Gary Beauchamp, Simon Lam, Ken Lazaris-Brunner
