Abstract

In embodiments of the present invention, improved capabilities are described for powering, controlling, and operating a home audio visual system using a mesh network that includes an energy savings mode based at least in part on intermittently powered mesh network nodes that are associated with the home audio-visual system. In embodiments, the intermittently powered mesh network nodes may periodically wake up, listen for wake up calls and/or initiate a full power mode in the home audio visual system when a intermittently power mesh network node is awakened and receives a subsequent full power instruction. Intermittently powered mesh network nodes may be further associated with instruction routing that utilizes silent acknowledgement.

Claims (31)

1. A method comprising:

providing a home audio-visual system that includes an energy savings mode;

providing an intermittently powered mesh network node in association with the home audio-visual system, wherein the intermittently powered mesh network node comprises a plurality of receive demodulators, and further comprising allowing a first demodulator that detects a valid signal to take control of receiving a subsequent transmission;

adapting the intermittently powered mesh network node to periodically wake up, listen for a wake up call and initiate a full power mode in the home audio-visual system when the intermittently powered mesh network node is awakened and receives a subsequent full power instruction; and

further comprising acknowledging the wake up call with a silent acknowledgement, in which the wake up call from a source node is sent to a node of the home audio-visual system by an intermediate node, and the source node detects transmission of the wake up call by the intermediate node to the home audio visual system without a specific acknowledgement message to the source node.

2. The method of claim 1 wherein the energy savings mode of the home audio-visual system draws a low amount of external power.

3. The method of claim 2 , wherein the low amount of external power is in the range of 0-1 mA.

4. The method of claim 1 , wherein the energy savings mode of the home audio-visual system draws no external power.

5. The method of claim 4 , wherein the full power instruction is used to close a power relay.

6. The method of claim 1 , wherein the full power instruction is used to provide power to an integrated circuit.

7. The method of claim 1 , wherein the full power instruction is used to provide a power supply to a control circuit.

8. The method of claim 7 , wherein the control circuit is used to perform quality surveillance of a mesh network power supply.

9. The method of claim 1 , wherein the intermittently powered mesh network node requests configuration information when the intermittently powered mesh network node powers up.

10. The method of claim 1 , wherein the intermittently powered mesh network node transmits a command when the intermittently powered mesh network node powers up.

11. The method of claim 1 , wherein the intermittently powered mesh network node acknowledges a command when the intermittently powered mesh network node powers up.

12. The method of claim 1 , wherein the intermittently powered mesh network node responds to a node request when the intermittently powered mesh network node powers up.

13. The method of claim 1 , wherein the intermittently powered mesh network node is powered at least in part using a battery, a fuel cell, a solar cell, an alternative energy source, an AC power source, or DC power source.

14. 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.

15. A method comprising:

providing a home audio-visual system that includes an energy savings mode;

providing an intermittently powered mesh network node in association with the home audio-visual system, wherein the intermittently powered mesh network node comprises a plurality of receive demodulators, and further comprising allowing a first demodulator that detects a valid signal to take control of receiving a subsequent transmission; and

adapting the intermittently powered mesh network node to periodically wake up, listen for a wake up call and initiate a full power mode in the home audio-visual system when the intermittently powered mesh network node is awakened and receives a subsequent full power instruction; wherein the wake up call is routed to the intermittently powered mesh network node using silent acknowledgement.

16. The method of claim 15 , wherein the energy savings mode of the home audio-visual system draws a low amount of external power.

17. The method of claim 16 , wherein the low amount of external power is in the range of 0-1 mA.

18. A method comprising:

providing a home audio-visual system that includes an energy savings mode;

providing an intermittently powered mesh network node in association with the home audio-visual system, wherein the intermittently powered mesh network node is a battery-powered node, wherein the intermittently powered mesh network node comprises a plurality of receive demodulators, and further comprising allowing a first demodulator that detects a valid signal to take control of receiving a subsequent transmission; and

adapting the intermittently powered mesh network node to periodically wake up, listen for a wake up call and initiate a full power mode in the home audio-visual system when the intermittently power mesh network node is awakened and receives a subsequent full power instruction; and

further comprising acknowledging the wake up call with a silent acknowledgement, in which the wake up call from a source node is sent to a node of the home audio-visual system by an intermediate node, and the source node detects transmission of the wake up call by the intermediate node to the home audio visual system without a specific acknowledgement message to the source node.

19. The method of claim 18 , wherein the energy savings mode of the home audio-visual system draws a low amount of external power.

20. The method of claim 19 , wherein the low amount of external power is in the range of 0-1 mA.
