Abstract

Methods and systems are provided for band translation with protection. A signal processing circuitry (chip) may be configured to receive and process a plurality of input signals, and generate one or more output signals based on the plurality of input signals. The processing may comprise determining when including a component of a first input signal into at least one output signal would have an effect on a component of a second input signal that is also to be included in the output signal, and applying, based on the effect, one or more adjustments to processing of one or both of the first signal and the second signal to mitigate the effect before generating the output signal. In this regard, applying the one or more adjustments may comprise applying one or both of filtering and spectral inversion to one or both of the first signal and the second signal.

Claims

1-20. -20. (canceled)

21. A method, comprising:

processing, via a signal processing chip, a plurality of input signals;

determining, during said processing, when including a component of a first signal from said plurality of input signals into at least one output signal would have an effect on a component of a second signal from said plurality of input signals that is also to be included in said at least one output signal; and

applying, based on said effect, one or more adjustments to processing of one or both of said first signal and said second signal to mitigate said effect before generating output signals based on said plurality of input signals; and

generating one or more output signals based on said plurality of input signals.

22. The method of claim 21, wherein applying said one or more adjustments comprises applying spectral inversion to one or both of said first signal and said second signal.

23. The method of claim 21, wherein applying said one or more adjustments comprises applying filtering to one or both of said first signal and said second signal.

24. The method of claim 21, comprising configuring said one or more adjustments to adjust one or more characteristics of said at least one output signal that are associated with one or both of said component of said first signal and said component of said second signal.

25. The method of claim 24, wherein adjusting said one or more characteristics comprises modifying one or more frequency bands, within said at least one output signal, assigned to one or both of said component of said first signal and said component of said second signal.

26. The method of claim 21, comprising determining, when assessing said effect, whether said component of said first signal and said component of said second signal will overlap within a same frequency band in said at least one output signal.

27. The method of claim 21, wherein one of said first signal and said second signal is associated with internal communications within an in-premises network.

28. The method of claim 27, wherein said internal communications comprise Multimedia over Coax Alliance (MoCA) based communications, and said one of said first signal and said second signal comprises a MoCA signal.

29. The method of claim 27, wherein other one of said first signal and said second signal is received from a source external to said in-premises network.

30. The method of claim 29, wherein said source external to said in-premises network comprises a satellite, and said other one of said first signal and said second signal comprises a satellite signal.

31. A system, comprising:

plurality of input circuits, each configured to receive one of a plurality of input signals; and

one or more processing circuits configured to process said plurality of input signals, wherein said one or more processing circuits are operable to;

determine, during said processing of said plurality of input signals, when including a component of a first signal from said plurality of input signals into at least one output signal would have an effect on a component of a second signal from said plurality of input signals that is also to be included in said at least one output signal;

apply, based on said effect, one or more adjustments to processing of one or both of said first signal and said second signal to mitigate said effect before generating output signals based on said plurality of input signals; and

generate one or more output signals based on said plurality of input signals.

32. The system of claim 31, wherein said one or more circuits are operable to, when applying said one or more adjustments, apply spectral inversion to one or both of said first signal and said second signal.

33. The system of claim 31, wherein said one or more circuits are operable to, when applying he one or more adjustments, apply filtering to one or both of said first signal and said second signal.

34. The system of claim 31, wherein said one or more circuits are operable to configure said one or more adjustments to adjust one or more characteristics of said at least one output signal that are associated with one or both of said component of said first signal and said component of said second signal are adjusted.

35. The system of claim 34, wherein adjustment of said one or more characteristics comprises modifying one or more frequency bands, within said at least one output signal, assigned to one or both of said component of said first signal and said component of said second signal.

36. The system of claim 31, wherein said one or more circuits are operable to determine, when assessing said effect, whether said component of said first signal and said component of said second signal will overlap within a same frequency band in said at least one output signal.

37. The system of claim 31, wherein one of said first signal and said second signal is associated with internal communications within an in-premises network.
