Abstract

In embodiments of the present invention, improved capabilities are described for a home audio-visual system that is at least in part controlled through a mesh network, wherein the home audio-visual system produces at least two effects. Each of the at least two effects may be controlled through separate mesh network nodes responsive to user initiated instructions. Each of the separate mesh network nodes may be adapted to receive the user initiate instructions through a channel management operation. In embodiments of the present invention, a home audio-visual system may communicate information through a mesh network, wherein the home audio-visual system includes one or more electrical devices that produce the information. The home audio-visual system may be associated with a channel management operation that is associated with one or more nodes of the mesh network to effect the communication of the information. In embodiments of the present invention, a media server may be enabled to control the delivery of a plurality of media content streams to a plurality of electrical devices, wherein the media server is adapted to be controlled through a mesh network node using a mesh network channel management operation. In embodiments, a command to the media server through the mesh network node may be transmitted in response to a user initiated instruction input to a hand held remote control, causing the mesh network node to receive the user initiated command through manipulation of a channel control operation. In embodiments, the media server may control the delivery of at least one of the plurality of media content streams to at least one of the plurality of electrical devices based on the user initiated command.

Claims

1. A method comprising:

providing a home audio-visual system that is at least in part controlled through a mesh network, wherein the home audio-visual system produces at least two effects;

controlling each of the at least two effects through separate mesh network nodes responsive to user initiated instructions; and

adapting each of the separate mesh network nodes to receive the user initiated instructions through a channel management operation.

2. The method of claim 1, wherein the channel management operation involves selecting a communication transmission speed.

3. The method of claim 1, wherein the channel management operation involves selecting a communication channel.

4. The method of claim 1, wherein the channel management operation involves performing a silent acknowledgement operation.

5. The method of claim 1, wherein at least one of the at least two effects is an audio effect.

6. The method of claim 1, wherein at least one of the at least two effects is a visual effect.

7. The method of claim 1, wherein at least one of the at least two effects is a room darkening effect.

8. The method of claim 1, wherein at least one of the at least two effects is a room illumination effect.

9. The method of claim 1, wherein the user initiated instruction is adapted to control each of the at least two effects simultaneously.

10. The method of claim 1, wherein a single user initiated instruction is adapted to control each of the at least two effects.

11. The method of claim 1, wherein the home audio-visual system includes at least one of a television, a satellite receiver, a cable converter, a VCR, a digital video disc player, a laser disc player, a video accessory, an audio amplifier, an audio tuner, an audio amplifier-tuner combination, a CD player, a DVD player, a high definition DVD player, an audio cassette player, a digital audio tape player, an audio equipment, an equalizer, a phonograph player, a video component, a streaming media player, an mp3 player, a light, a lamp, a gateway, a modem, or ISDN.

12. A method comprising:

providing a home audio-visual system that communicates information through a mesh network, wherein the home audio-visual system includes one or more electrical devices that produce the information; and

controlling a channel management operation associated with one or more nodes of the mesh network to effect the communication of the information.

13. The method of claim 12, wherein the information is communicated to a user.

14. The method of claim 12, wherein the information relates to an audio-visual system setting.

15. The method of claim 12, wherein the information relates to metadata.

16. The method of claim 12, wherein the information is control information intended to be used by at least one of the one or more electrical devices within the audio-visual system.

17. A method comprising:

providing a media server enabled to control the delivery of a plurality of media content streams to a plurality of electrical devices, wherein the media server is adapted to be controlled through a mesh network node using a mesh network channel management operation;

transmitting a command to the media server through the mesh network node in response to a user initiated instruction input to a hand held remote control;

causing the mesh network node to receive the user initiated command through manipulation of the channel control operation; and

causing the media server to control the delivery of at least one of the plurality of media content streams to at least one of the plurality of electrical devices based on the user initiated command.

18. The method of claim 17, wherein the channel management operation involves selecting a communication transmission speed.

19. The method of claim 17, wherein the channel management operation involves selecting a communication channel.

20. The method of claim 17, wherein the channel management operation involves performing a silent acknowledgement operation.
