Abstract

An embodiment of an apparatus for distributing a digital audio signal includes a digital audio to packet data converter configured to receive a digital audio signal and convert the digital audio signal to a packetized audio data stream. The embodiment of the apparatus further includes a wireless packet data transmitter configured to transmit the packetized audio data stream over a wireless connection, and a wired packet data transmitter configured to transmit the packetized audio data stream over a wired network connection. The embodiment of the apparatus further includes a powerline packet data transmitter configured to transmit the packetized audio data stream over a powerline network connection.

Claims

1. An apparatus for distributing a digital audio signal comprising:

a digital audio to packet data converter configured to receive a digital audio signal and convert the digital audio signal to a packetized audio data stream;

a wireless packet data transmitter configured to transmit the packetized audio data stream over a wireless connection;

a wired packet data transmitter configured to transmit the packetized audio data stream over a wired network connection; and

a powerline packet data transmitter configured to transmit the packetized audio data stream over a powerline network connection.

2. The apparatus of claim 1, further comprising:

a distribution module configured to receive the packetized audio data stream and selectively distribute the packetized audio data stream to at least one of the wireless packet data transmitter, the wired packet data transmitter, and the powerline packet data transmitter.

3. The apparatus of claim 2, wherein the distribution module is further configured to allow a user to select to which of the wireless packet data modulator, the wired packet data modulator and the powerline packet data modulator that the packetized audio data stream is to be distributed.

4. The apparatus of claim 1, further comprising:

an analog to digital converter configured to receive an analog audio signal and convert the analog audio signal into the digital audio signal, the analog to digital converter further configured to provide the digital audio signal to the digital audio to packet data converter.

5. The apparatus of claim 4, further comprising:

at least one analog audio input connector in communication with the analog to digital converter, the at least one digital audio input connector configured to receive the analog audio signal and provide the analog audio signal to the analog to digital converter.

6. The apparatus of claim 5, wherein the at least one analog audio input connector includes at least one of a left/right analog RCA input connector pair, a left/right speaker-level analog input connector pair, and a left/right audio input jack.

7. The apparatus of claim 1, further comprising:

at least one digital audio input connector in communication with the digital audio to packet data converter, the at least one digital audio input connector configured to receive the digital audio signal and provide the digital audio signal to the digital audio to packet data converter.

8. The apparatus of claim 7, wherein the at least one digital audio input connector includes at least one of a docketing station input connector, an S/PDIF input connector, and a USB input connector.

9. The apparatus of claim 1, further comprising:

a wired network connector configured to receive the packetized audio data stream from the wired packet data transmitter, the wired network connector further configured to be coupled to a wired network and transmit the packet audio data stream to the wired network.

10. The apparatus of claim 1, further comprising:

a powerline network connector configured to receive the packetized audio data stream from the powerline packet data transmitter, the powerline network connector further configured to be coupled to a powerline network and transmit the packet audio data stream to the powerline network.

11. The apparatus of claim 1, wherein the digital audio to packet data converter, the wireless packet data transmitter, the wired packet data transmitter, and the powerline packet data transmitter are contained within a single enclosure.

12. The apparatus of claim 1, wherein the packetized audio data stream includes Ethernet packets.

13. An apparatus for receiving a distributed digital audio signal comprising:

a wireless packet data receiver configured to receive a packetized audio data stream over a wireless connection;

a wired packet data receiver configured to receive the packetized audio data stream over a wired network connection;

a powerline packet data receiver configured to receive the packetized audio data stream over a powerline network connection; and

a packet data to digital audio converter configured to receive the packetized audio data stream from at least one of the wireless packet data receiver, the wired packet data receiver, and the powerline packet data receiver, the packet data to digital audio converter further configured to convert the packetized audio data stream to a digital audio signal.

14. The apparatus of claim 13 further comprising:

a digital to analog converter configured to receive the digital audio signal from the packet data to digital audio converter and convert the digital audio signal to at least one analog audio signal.

15. The apparatus of claim 13 further comprising:

an audio amplifier configured to receive the at least analog audio signal and convert the at least one analog signal to at least one speaker-level analog output signal.

16. The apparatus of claim 15 further comprising:

at least one speaker-level output connector configured to receive the at least one speaker-level analog output signal.

17. The apparatus of claim 16, wherein the at least one speaker-level output connector is further configured to be coupled to at least one audio loudspeaker.

18. The apparatus of claim 13 further comprising:

a wired network input connector configured to receive the packetized audio data stream from a wired network and provide the packetized audio data stream to the wired packet data receiver.

19. The apparatus of claim 13 further comprising:

a powerline network input connector configured to receive the packetized audio data stream from a powerline network and provide the packetized audio data stream to the powerline packet data receiver.

20. The apparatus of claim 13, wherein the wireless packet data receiver, the wired packet data receiver, the powerline packet data receiver, and the packet data to digital audio to converter are contained within a single enclosure.
