Band translation with protection of in-home networks

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.
