Patent ID: 7346332

Claim:
An apparatus for receiving an audio signal via a powerline network, the apparatus comprising: a housing; a powerline module located in the housing, the power line module comprising: a frequency converting module configured to convert a powerline signal of an intermediate frequency, received via a powerline network, into a baseband signal; an A/D converting module configured to convert the baseband signal into a digital signal; a signal processing module configured to convert the digital signal into a combined signal; and a powerline magnetics module configured to provide isolation between the powerline network and the frequency converting module, the frequency converting module operating on a substantially lower voltage than the powerline network; a receiver module located in the housing and configured to extract a control signal and an audio signal from the converted combined signal, the receiver module manipulating the audio signal based on the extracted control signal; a plug coupled to the housing and configured for insertion into an electrical receptacle; a power supply in the housing, coupled to the plug and configured to distribute electrical energy to the receiver module; and an output wire configured to couple the housing to an output device.
