System and method in a broadband receiver for efficiently receiving and processing signals
View Patent ↗A system and method in a broadband receiver (e.g., a satellite television receiver) for efficiently receiving and processing signals, substantially as shown in and/or described in connection with at least one of the figures, as set forth more completely in the claims.
1. A satellite dish system for receiving satellite signals, said satellite dish system comprising:
at least one module comprising a first full-band capture receiver and a second full-band capture receiver communicatively coupled to a low noise block downconverter (LNB) wherein:
said first full-band capture receiver is operable to, at least:
receive a first signal from said LNB; and
digitize the received first signal over all frequencies of the first signal that are used for carrying satellite television signal, the digitization resulting in a first digitized signal; and
said second full-band capture receiver is operable to, at least:
receive a second signal from said LNB; and
digitize the received second signal over all frequencies of the second signal that are used for carrying satellite television signal, the digitization resulting in a second digitized signal.
2. The satellite dish system of claim 1 , wherein said at least one module comprises a digital channelizer communicatively coupled to said first full-band capture receiver and said second full-band capture receiver and operable to, at least:
receive said first digitized signal from said first full-band capture receiver, the received first digitized signal comprising a first plurality of channels;
receive said second digitized signal from said second full-band capture receiver, the received second digitized signal comprising a second plurality of channels;
select a portion of the first plurality of channels and second plurality of channels; and
output one or more digital signals comprising the selected portion.
3. The satellite dish system of claim 2 , wherein said digital channelizer comprises a polyphase filter and is operable to utilize said polyphase filter to select the portion of the plurality of channels.
4. The satellite dish system of claim 2 , wherein said digital channelizer comprises an FFT engine and said selection of said portion of the plurality of channels comprises, at least in part;
utilization of said FFT engine to calculate a running FFT of the received first digitized signal received from said first full-band capture receiver; and
selection of outputs of said FFT engine for further processing.
5. The satellite dish system of claim 2 , wherein said at least one module comprises a demodulator communicatively coupled to said digital channelizer and operable to, at least:
receive the output one or more digital signals from said digital channelizer;
convert the output one or more digital signals received from said digital channelizer to one or more transport streams; and
output the one or more transport streams.
6. The satellite dish system of claim 5 , wherein said at least one module comprises an IP bridge communicatively coupled to said demodulator and operable to encapsulate at least a portion of the one or more transport streams in IP packets.
7. The satellite dish system of claim 2 , where said one or more digital signals comprising the selected portion is a single digital signal.
8. The satellite dish system of claim 1 , wherein said first and second full-band capture receivers capture substantially identical frequency bands.
9. The satellite dish system of claim 1 , wherein said at least one module comprises an IP bridge operable to encapsulate at least a portion of the one or more digital signals in IP packets.
10. The satellite dish system of claim 9 , wherein said IP bridge is operable to perform packet identification (PID) filtering to select only a portion of the one or more digital signals for encapsulation in said IP packets.
11. The satellite dish system of claim 9 , wherein said at least one module comprises a communication interface module operable to communicate the IP packets to a device external to the satellite dish system.
12. The satellite dish system of claim 11 , wherein said communication interface module is operable to communicate the IP packets to the device external to the satellite dish system utilizing a communication protocol specifically adapted for communication with in-home devices over a television cable medium.
13. The satellite dish system of claim 1 , where the device external to the satellite dish system is an in-the-home device.
14. The satellite dish system of claim 13 , where the device external to the satellite dish system is a home gateway.
15. The satellite dish system of claim 13 , where the device external to the satellite dish system is different from a set top box.
16. The satellite dish system of claim 13 , where the device external to the satellite dish system is a network controller of an in-the-home communication network.
17. The satellite dish system of claim 1 , where the device external to the satellite dish system is a general purpose data communication device that is not specifically adapted for satellite communication.
