Frequency pairing for device synchronization
A device may include a processor, a receiver, and a transmitter. The receiver may be configured to receive a content signal. The transmitter may be configured to transmit the content signal. The transmitter may be configured to transmit an associated inaudible signal. The content signal, the associated inaudible signal, or both, may be transmitted to one or more electronic devices. Each of the one or more electronic devices may be configured with audio interfaces. The receiver may be configured to receive a respective message from each of the one or more electronic devices. Each respective message may be based on the associated inaudible signal. Each respective message may include a respective electronic device identifier. The transmitter may be configured to transmit one of the respective messages.
1. A method for removing duplicate messages received at an I/O device, the method comprising:
receiving, at the input/output (I/O) device, an audible signal and an associated inaudible signal from a media service;
transmitting, to a plurality of electronic devices, the inaudible signal, the inaudible signal causing the plurality of electronic devices to await an input from a user, the input associated with the audible signal;
receiving, from a first electronic device of the plurality of electronic devices, a first message based on the user input, wherein the first message instructs the I/O device to perform an action;
receiving, from at least one other electronic device, a duplicate message of the first message; and
removing duplicate messages received at the I/O device.
2. The method of claim 1 , further comprising transmitting the first message to the media service.
3. The method of claim 1 , further comprising receiving a predetermined contextual response from the first electronic device, wherein the predetermined contextual response is based on the inaudible signal.
4. The method of claim 1 , wherein the inaudible signal and the audible signal are transmitted from the I/O device in parallel.
5. The method of claim 1 , further comprising associating the user input with a user identifier (ID), a content ID, or both.
6. The method of claim 1 , wherein the inaudible signal comprises a frequency signature, a wake command, an instruction, a content ID, a source ID, or any combination thereof.
7. The method of claim 6 , wherein the frequency signature is receivable by an electronic device type of the plurality of electronic devices.
8. The method of claim 1 , wherein the first message further comprises one or more of a user ID, a content ID, and a device ID.
9. The method of claim 1 , wherein the audible signal and the inaudible signal are received from the media service as a single multiplexed signal.
10. The method of claim 1 , wherein the audible signal and the inaudible signal are received from the media service separately.
11. The method of claim 1 , wherein the user input is a voice input or a gesture.
12. The method of claim 1 , wherein an application on the I/O device receives the instruction in the first message and performs the action.
13. A system comprising:
a media service;
an input/output (I/O) device configured to:
receive an audible signal and an associated inaudible signal from the media service;
transmit the inaudible signal to a plurality of electronic devices;
receive a first message, wherein the first message instructs the I/O device to perform an action;
receive duplicate messages of the first message; and
remove duplicate messages; and
a plurality of electronic devices, each electronic device comprising:
a receiver configured to receive the inaudible signal, the inaudible signal causing the plurality of electronic devices to enter a receiving mode;
a monitor to detect an input from a user, the input associated with the audible signal; and
a transmitter configured to transmit, to the I/O device, a message based on the user input, wherein the transmitted message instructs an application on the I/O device to perform an action.
14. The system of claim 13 , the I/O device further configured to transmit the first message to the media service.
15. The system of claim 13 , wherein the transmitter of the plurality of electronic devices is further configured to queue a contextual response based on the inaudible signal received from the I/O device, wherein the contextual response is based on the inaudible signal.
16. The system of claim 13 , wherein the inaudible signal and the audible signal are transmitted from the I/O device in parallel.
17. The system of claim 13 , wherein the first message further comprises one or more of a user ID, a content ID, and a device ID.
18. The system of claim 15 , wherein the inaudible signal comprises a frequency signature, wherein the frequency signature is receivable by an electronic device type of the plurality of electronic devices.
19. The system of claim 13 , wherein the audible signal and the inaudible signal are transmitted by the media service as a single multiplexed signal.
20. The system of claim 13 , wherein the audible signal and the inaudible signal are transmitted by the media service separately.
