Wireless streaming system with low power mode and associated remote control
A wireless streaming system includes a wireless network interface circuit to receive streaming content from a wireless router. A processor is connected to the wireless network interface circuit. A memory is connected to the processor. The memory stores instructions executed by the processor to enter a sleep mode that periodically invokes a wireless interface chip off state and a wireless interface chip on state. The sleep mode is exited in response to the receipt of a wake packet observed during the wireless interface chip on state.
1. A remote control, comprising:
a wireless interface circuit configured to communicate with a wireless media system, wherein the wireless media system periodically invokes a wireless interface chip on state and off state; and
a processor coupled to the wireless interface circuit, the processor configured to:
identify a remote control input during a sleep state of the remote control;
probe the wireless media system in response to the remote control input;
identify a lack of response to the probe by the wireless media system; and
continuously transmit a message to the wireless media system via the wireless interface circuit until the wireless interface circuit detects that the wireless media system has received the message during a wireless media system on state, wherein the message is a wake message.
2. The remote control of claim 1 , wherein the processor is further configured to:
enter the sleep state in response to a sleep state command.
3. The remote control of claim 1 , wherein the processor is further configured to:
enter the sleep mode in response to an absence of activity by the wireless media system for a period of time exceeding a threshold.
4. The remote control of claim 1 , wherein the wake message is a packet associated with a Wake on Wireless Local Area Network (WoWLAN) standard.
5. The remote control of claim 1 , wherein the remote control input comprises a detection of an accelerometer signal exceeding a threshold.
6. The remote control of claim 1 , wherein the processor is further configured to periodically transmit the message to the wireless media system until the wireless interface circuit receives a response from the wireless media system.
7. A method, comprising:
identifying a remote control input during a sleep state of a remote control;
probing a wireless media system in response to identifying the remote control input, wherein the wireless media system periodically invokes a wireless interface chip on state and off state;
identifying a lack of response to the probe by the wireless media system; and
continuously transmitting a message to the wireless media system via a wireless interface circuit until detecting that the wireless streaming system has received the message during a wireless media system on state, wherein the message is a wake message.
8. The method of claim 7 , further comprising:
entering the sleep state in response to a sleep state command.
9. The method of claim 7 , further comprising:
entering the sleep mode in response to an absence of activity by the wireless media system for a period of time exceeding a threshold.
10. The method of claim 7 , wherein the wake message is a packet associated with a Wake on Wireless Local Area Network (WoWLAN) standard.
11. The method of claim 7 , wherein the remote control input comprises a detection of an accelerometer signal exceeding a threshold.
12. The method of claim 7 , further comprising:
periodically transmitting the message to the wireless media system until receiving a response from the wireless media system.
13. A non-transitory computer-readable device having instructions stored thereon that, when executed by at least one computing device, causes the at least one computing device to perform operations comprising:
identifying a remote control input during a sleep state of a remote control;
probing a wireless media system in response to identifying the remote control input, wherein the wireless media system periodically invokes a wireless interface chip on state and off state;
identifying a lack of response to the probe by the wireless media system; and
continuously transmitting a message to the wireless media system via a wireless interface circuit until detecting that the wireless streaming system has received the message during a wireless media system on state, wherein the message is a wake message.
14. The computer-readable device of claim 13 , the operations further comprising:
entering the sleep state in response to a sleep state command.
15. The computer-readable device of claim 13 , the operations further comprising:
entering the sleep mode in response to an absence of activity by the wireless media system for a period of time exceeding a threshold.
16. The computer-readable device of claim 13 , wherein the remote control input comprises a detection of an accelerometer signal exceeding a threshold.
17. The computer-readable device of claim 13 , the operations further comprising:
periodically transmitting the message to the wireless media system until receiving a response from the wireless media system.
18. The remote control of claim 1 , wherein the wake message is an unencrypted wake packet.
19. The method of claim 7 , wherein the wake message is an unencrypted wake packet.
20. The computer-readable device of claim 13 , wherein the wake message is an unencrypted wake packet.
