Abstract

A signal receiver chip may be configured to handle a plurality of satellite signals. In this regard, for each received satellite signal the signal receiver chip may determine whether the received satellite signal is unprocessed or partially-processed off-chip; and when the received satellite signal is partially-processed off-chip, at least a portion of processing functions performed in the signal receiver chip may be bypassed. The received satellite signals may then be processed, to generate a corresponding output signals that is configured for communication over a local link. The processing functions bypassed in the signal receiver chip may comprise signal band conversion, particularly down converting from a first band used for over-the-air communication to a second band that is used during handling at receiver side. In this regard, the first band comprises K-band, Ku-band, or Ka-band, whereas the second band comprises L-band, half-L-band, or Extended-L-band.

Claims (35)

1. A system, comprising:

one or more circuits for use in a signal receiver chip that is configured to handle a plurality of satellite signals, the one or more circuits being operable to:

for each received satellite signal:

determine whether the received satellite signal is an unprocessed signal or is partially-processed off-chip;

when the received satellite signal is partially-processed off-chip, bypass at least a portion of processing functions performed in the signal receiver chip; and

process the received satellite signal to generate a corresponding output signal that is configured for communication over a local link.

2. The system of claim 1 , wherein the at least portion of processing functions bypassed in the signal receiver chip comprise signal band conversion.

3. The system of claim 2 , wherein the signal band conversion comprises down converting from a first band used for over-the-air communication to a second band that is used during handling at receiver side.

4. The system of claim 3 , wherein the first band comprises K-band, Ku-band, or Ka-band.

5. The system of claim 3 , wherein the second band comprises L-band, half-L-band, or Extended-L-band.

6. The system of claim 1 , wherein the local link that is configured based on one or more of: a coaxial cable connection, a twisted-pair connection, a Multimedia over Coax Alliance (MoCA) connection, an Ethernet connection, or a Direct Broadcast Satellite (DBS) based connection.

7. The system of claim 1 , wherein the output signal is communicated to a gateway device that distributes content carried in the output signal, to a plurality of client services in a network serviced by the gateway device.

8. The system of claim 7 , wherein the gateway device comprises a satellite set-top box (STB).

9. The system of claim 6 , wherein the one or more circuits are operable to combine a plurality of portions corresponding to multiple ones of the pluralities of satellite signals, into a single output signal.

10. A method, comprising:

receiving and handling by a signal receiver chip, each of a plurality of satellite signals, wherein handling each satellite signal comprises:

determining whether the received satellite signal is an unprocessed signal or is partially-processed off-chip;

when the received satellite signal is partially-processed off-chip, bypassing at least a portion of processing functions performed in the signal receiver chip; and

processing the received satellite signal to generate a corresponding output signal that is configured for communication over a local link.

11. The method of claim 10 , wherein the at least portion of processing functions bypassed in the signal receiver chip comprise signal band conversion.

12. The method of claim 11 , wherein the signal band conversion comprises down converting from a first band used for over-the-air communication to a second band that is used during handling at receiver side.

13. The method of claim 12 , wherein the first band comprises K-band, Ku-band, or Ka-band.

14. The method of claim 12 , wherein the second band comprises L-band, half-L-band, or Extended-L-band.

15. The method of claim 10 , comprising configuring the local link based on one or more of: a coaxial cable connection, a twisted-pair connection, a Multimedia over Coax Alliance (MoCA) connection, an Ethernet connection, or a Direct Broadcast Satellite (DBS) based connection.

16. The method of claim 10 , comprising communicating the output signal to a gateway device that distributes content carried in the output signal, to a plurality of client services in a network serviced by the gateway device.

17. The method of claim 16 , wherein the gateway device comprises a satellite set-top box (STB).

18. The method of claim 10 , wherein the one or more circuits are operable to combine a plurality of portions corresponding to multiple ones of the pluralities of satellite signals, into a single output signal.

19. A system, comprising:

a signal receiver chip that is configured to handle a plurality of received satellite signals, the signal receiver chip comprising:

a plurality of first input processing paths, for handling one or more received satellite signals that are unprocessed signals or are partially-processed off-chip;

a plurality of second input processing paths, for handling one or more received satellite signals that are partially-processed off-chip;

one or more circuits for processing input signals, wherein processing the input signals comprises recovering or extracting data carried by the plurality of received satellite signals; and

one or more circuits for generating output signals based on processing of the plurality of received satellite signals.

20. The system of method 19 , wherein each of the plurality of first input processing paths comprises signal conversion circuitry, for down converting a satellite signals handled thereby from a first band used for over-the-air communication to a second band that is used during handling within the signal receiver chip.

21. The system of method 19 , wherein the signal receiver chip comprises one or more local oscillator (LO) components for generating local signals during processing of the plurality of received satellite signals.
