Abstract

A method and system for communicating audio, video, and/or control signals within a home entertainment system. One or more signals are communicated between an input device and one or more output devices via one or more networks. The output device can include loudspeakers, display devices, and headphones. In some embodiments an output device, for example a center channel loudspeaker, transmits signals to other output devices. For example, the center channel loudspeaker can transmit a combined audio signal and control signal to a remote loudspeaker over a first network and transmit a video signal to a display device over a second network. The display device displays the video signal. The networks can be wireless, wired, infrared, RF, and powerline.

Claims

1. A system comprising:

a first housing for a loudspeaker, the first housing having therein

a first loudspeaker configured to play audio signals,

an audio input configured to receive a multi-channel audio signal,

a processor configured to convert the received multi-channel audio signal into a plurality of single-channel audio signals, each single-channel audio signal representing a different portion or channel of the multi-channel audio signal and being assigned to either a first group of audio signals or a second group of audio signals, not both, each group comprising at least one of the single-channel audio signals,

an amplifier module wired to the processor and configured to amplify the first group of audio signals and then drive the first loudspeaker with the amplified first group of audio signals, and

a wireless transmitter configured to transmit i) the second group of audio signals and ii) data indicative of user input, as a combined signal, to a separate, second housing having therein a second loudspeaker, wherein, during playback of the multi-channel audio signal, the processor is further configured to route i) the first group of the audio signals, not the second group, to the amplifier module, and ii) the second group of audio signals, not the first group, to the wireless transmitter.

2. The system of claim 1 further comprising an input device external to the first and second housings and configured to transmit i) the multi-channel audio signal to the audio input in the first housing and ii) the user input to the processor in the first housing.

3. The system of claim 2 wherein the user input comprises a selection made by a user that the second loudspeaker be used to play the multi-channel audio signal.

4. The system of claim 2 wherein the user input comprises at least one of the following:

a volume level, a balance level, a fader level, and a sub-bass level.

5. The system of claim 1 wherein the user input comprises at least one of the following:

a volume level, a balance level, a fader level, and a sub-bass level.

6. The system of claim 1 wherein the user input comprises a selection made by a user that the second loudspeaker be used to play the multi-channel audio signal.

7. The system of claim 1 further comprising an input device internal to the first housing and configured to transmit the multi-channel audio signal to the audio input in the first housing.

8. The system of claim 1 wherein the first group of audio signals comprises a center channel.

9. The system of claim 8 wherein the second group of audio signals comprises a left front channel, a right front channel, a surround left channel and a surround right channel.

10. The system of claim 1, wherein the first housing is a first home entertainment loudspeaker housing having integrated therein the first loudspeaker, the audio input, the processor, the amplifier module, and the wireless transmitter.

11. The system of claim 10, wherein the second housing is a second home entertainment loudspeaker housing having integrated therein the second loudspeaker.

12. The system of claim 11, wherein the second home entertainment loudspeaker housing is either a subwoofer or a surround sound speaker.

13. The system of claim 1 further comprising a display device that is configured to display a video signal associated with the multi-channel audio signal.

14. The system of claim 13, wherein the audio input is further configured to receive the video signal, along with the multi-channel audio signal, wherein the display device is further configured to receive the video signal through a wired or wireless connection with the first housing.
