Abstract
Multiple systems for delivering satellite signals are described. An apparatus in accordance with the present invention comprises a receive antenna, including at least one low noise block amplifier (LNB); and a module, coupled to and proximate the receive antenna, the module comprising a multiswitch, coupled to the LNB, for directing the satellite signal received by the LNB to an output of the multiswitch, at least one tuner, coupled to the output of the multiswitch, for tuning to a specific portion of the satellite signal, the specific portion of the satellite signal selected based on commands received from a new Integrated Receiver Decoder (IRD), at least one demodulator, coupled to the at least one tuner, for demodulating the specific portion of the signal into a plurality of demodulated signals, and an interface for delivering a specific demodulated signal to the new IRD, wherein the specific demodulated signal is selected based on the commands received from the new IRD, and the specific demodulated signal is mapped to a new address based on a private channel number associated with the new ERD.
Claims
AMENDED CLAIMS received by the International Bureau on 07 November 2007
(07.11.2007)
-33-
WHAT IS CLAIMED IS:
1. A system for delivering satellite signals, comprising: a receive antenna, including at least one low noise block amplifier (LNB); and a module, coupled to and proximate the receive antenna, the module comprising: a multiswitch, coupled to the LNB, for directing the satellite signal received by the LNB to an output of the multiswitch; at least one tuner, coupled to the output of the multiswitch, for tuning to a specific portion of the satellite signal, the specific portion of the satellite signal selected based on commands received from a new Integrated Receiver Decoder (IRD); at least one demodulator, coupled to the at least one tuner, for demodulating the specific portion of the signal into a plurality of demodulated signals; and an interface for delivering a specific demodulated signal to the new IRD3 wherein the specific demodulated signal is selected based on the commands received from the new IRD, and the specific demodulated signal is mapped to a new address based on a private channel number associated with the new IRD, the private channel number being determined by the module in response to a request from the IRD to the module for the private channel number.
2. The system of claim 1 , wherein the commands and the specific demodulated signal are carried on a single connection between at least one new IRD and the interface.
3. The system of claim 2, further comprising: a plurality of new IRDs, wherein each new IRD has a unique private channel number, and the interface delivers a combined signal comprising a plurality of specific demodulated signals, each demodulated signal selected based on commands received from each of the plurality of new IRDs,
-35-
10, A system for selectively delivering satellite video signals received from a plurality of satellites to at least one Integrated Receiver Decoder (IRD), comprising: a multiswitch, for selectively directing the satellite video signals based on which satellite of the plurality of satellites broadcast the satellite video signal to an output of the multiswitch; at least one tuner, coupled to the output of the multiswitch, for tuning to a specific portion of the satellite video signal, the specific portion of the satellite signal selected based on a command received from the IRD; at least one demodulator, coupled to the at least one tuner in a respective fashion, for demodulating the specific portion of the signal into a plurality of demodulated signals; and an interface for delivering a specific demodulated signal to the IRD, wherein the specific demodulated signal is mapped to a new address based on a private channel number associated with the IRD, the private channel number being determined by the module in response to a request from the IRD to the module for the private channel number.
11. The system of claim 10, further comprising an automatic gain controller, coupled between the multiswitch and the interface, for controlling the signal strengths of the specific demodulated signals.

16. The system of claim 15, wherein the interface has an output comprising a combined signal, which comprises a plurality of individual signals, a first individual signal comprising an output of the network tuner, and additional individual signals comprising at least one specific demodulated signal.
17. The system of claim 16, wherein the IRD receives the entire combined signal and tunes to the individual signals based on the new address associated with the individual signal,
18. A system for selectively delivering satellite video signals received from a plurality of satellites to at least one Integrated Receiver Decoder (IRD), comprising: a multiswitch, for selectively directing the satellite video signals based on which satellite of the plurality of satellites broadcast the satellite video signal to an output of the multiswitch; at least one tuner, coupled to the output of the multiswitch, for tuning to a specific portion of the satellite video signal, the specific portion of the satellite signal selected based on a command received from the IRD; and an interface for delivering the specific portion of the satellite signal to the IRD, wherein the portion is mapped to a new address based on a reassignable private channel number associated with the IRD, the reassignable private channel number being determined by the module in response to a request from the IRD to the module for the reassignable private channel number,
19. The system of claim 18, wherein the interface is a network interface.
