Energy efficient method for home networking
To reduce energy consumption in a low power mode, a display device such as a TV deenergizes its display and components in its network stack while leaving its infrared (IR) receiver on. A home network device that is not a conventional TV remote control (RC), for instance, a smart speaker, can receive a voice command to energize the TV, and instead of sending a wake up command to the TV through the home network, transmits an IR wake up command or sonic wake up command or non-IP RF command to the TV, which energizes its network stack and display in response.
1. An assembly, comprising:
at least one processor configured with instructions to:
enter a low power mode of a controlled appliance comprising the at least one processor in which at least one video display of the controlled appliance is not activated to display images and at least one computer network communication element and/or system on a chip (SOC) processor of the controlled appliance is deenergized;
responsive to an infrared (IR) command and/or sonic command and/or non-Internet Protocol (IP) radiofrequency (RF) command from a networked device, energize the video display and configure the at least one computer network communication element and the SOC processor in an energized mode that consumes more power than the low power mode; and
within a period of time under two seconds after receiving the IR command and/or sonic command and/or non-IP RF command from the networked device, receive from the networked device, using the at least one computer network communication element, an IP-based discovery message polling the controlled appliance to establish IP communication between the controlled appliance and the networked device.
2. The assembly of claim 1 , wherein the controlled appliance comprises a TV.
3. The assembly of claim 1 , wherein the networked device comprises an Internet of Things (IoT) device configured to communicate via IP over a computer network.
4. The assembly of claim 1 , wherein the at least one computer network communication element comprises at least a network layer, a transport layer, and an application layer in a network stack.
5. The assembly of claim 3 , wherein the computer network comprises a home entertainment network.
6. The assembly of claim 1 , wherein the networked device comprises a speaker assembly.
7. The assembly of claim 1 , wherein the instructions are executable to:
responsive to an IR command from the networked device, energize the video display and the at least one computer network communication element.
8. The assembly of claim 1 , wherein the instructions are executable to:
responsive to a computerized sonic chirp from the networked device, energize the video display and the at least one computer network communication element.
9. The assembly of claim 1 , wherein the instructions are executable to:
responsive to a non-IP RF command from the networked device, energize the video display and the at least one computer network communication element.
10. An assembly, comprising:
at least one processor configured with instructions to:
responsive to a command to energize a controlled appliance, transmit to the controlled appliance at least one infrared (IR) and/or sonic command and/or non-Internet Protocol (IP) radiofrequency (RF) command to cause the controlled appliance to activate at least one video display of the controlled appliance and at least one computer network communication element of the controlled appliance; and
within a period of time under two seconds after transmitting the IR command and/or sonic command and/or non-IP RF command to the controlled appliance, transmit to the controlled appliance an IP-based discovery message polling the controlled appliance to establish IP communication between the controlled appliance and the assembly.
11. The assembly of claim 10 , wherein the assembly comprises an Internet of Things (IoT) device configured to communicate via IP over a computer network.
12. The assembly of claim 10 , wherein the at least one computer network communication element comprises at least part of a network stack, the part comprising at least a network layer, a transport layer, and an application layer in the network stack.
13. The assembly of claim 10 , wherein the instructions are executable to:
responsive to the command to energize the controlled appliance, transmit to the controlled appliance at least one non-IP RF command to cause the controlled appliance to energize the at least one video display of the controlled appliance and the at least one computer network communication element of the controlled appliance.
14. The assembly of claim 10 , wherein the assembly comprises a speaker assembly.
15. The assembly of claim 10 , wherein the instructions are executable to:
responsive to the command to energize the controlled appliance, transmit to the controlled appliance at least one IR command to cause the controlled appliance to energize the at least one video display of the controlled appliance and the at least one computer network communication element of the controlled appliance.
16. The assembly of claim 10 , wherein the instructions are executable to:
responsive to the command to energize the controlled appliance, transmit to the controlled appliance at least one computer-generated sonic command to cause the controlled appliance to energize the at least one video display of the controlled appliance and the at least one computer network communication element of the controlled appliance.
