Activating functions in processing devices using encoded audio and detecting audio signatures
View Patent ↗Methods and apparatus for performing an action on a device based on audio are disclosed. An example method includes determining at a first device whether the audio includes a monitoring code indicating that the audio is to be monitored, generating a signature using a portion of the audio containing the monitoring code, and causing the action to be performed on a second device based on at least one of the monitoring code or the signature.
1. A method of performing an action based on audio, the method comprising:
determining, by executing an instruction with a processor, at a first device whether the audio includes a monitoring code indicating that the audio is to be monitored;
in response to the monitoring code being located in the audio, generating, by executing an instruction with the processor, a signature using a portion of the audio containing the monitoring code; and
transmitting, by executing an instruction with the processor, a control signal to a second device via a network communication based on at least one of the monitoring code or the signature, the control signal to cause the second device to perform the action.
2. The method of claim 1 , further including causing a second action to be performed on the first device based on at least one of the monitoring code or the signature.
3. The method of claim 1 , wherein the first device controls the performance of the action on the second device.
4. The method of claim 1 , wherein the audio includes a second monitoring code, the second monitoring code received at the first device after the monitoring code, and further generating the signature based on an audio portion located before the second monitoring code.
5. The method of claim 1 , wherein the audio further includes a source identification code indicating a source of the audio, and further generating the signature based on the source identification code.
6. The method of claim 1 , further including generating a plurality of signatures at time intervals in response to the monitoring code being located in the audio.
7. The method of claim 1 , wherein the action includes at least one of displaying an image, displaying text, displaying a web page, playing a video, playing audio, or executing software on the second device.
8. A device comprising:
a detector to detect a monitoring code located in audio, the monitoring code indicating that the audio is to be monitored; and
a processor to:
generate a signature in response to the detected monitoring code, the signature generated based on a portion of the audio containing the monitoring code, and
transmit a control signal to a second device via a network communication based on at least one of the monitoring code or the signature, the control signal to cause the second device to perform an action.
9. The device of claim 8 , wherein the processor is further to cause a second action to be performed on the second device.
10. The device of claim 8 , wherein the detector is to detect a second monitoring code in the audio, the second monitoring code to be received after the monitoring code, the processor to generate the signature based on a second portion of the audio located before the second monitoring code.
11. The device of claim 8 , wherein the audio further includes a source identification code indicating a source of the audio, the processor to generate the signature based on the source identification code.
12. The device of claim 8 , wherein the processor is further to generate a plurality of signatures at time intervals in response to the monitoring code being located in the audio.
13. The device of claim 8 , wherein the action includes at least one of displaying an image, displaying text, displaying a web page, playing a video, playing audio, or executing software on the second device.
14. A tangible computer readable storage device or storage disk comprising instructions that, when executed, cause a first device to at least:
detect at the first device a monitoring code located in audio indicating that the audio is to be monitored;
in response to the detected monitoring code, generate a signature using a portion of the audio containing the monitoring code; and
transmit a control signal via a network connection to a second device based on at least one of the monitoring code or the signature, the control signal to cause the second device to perform an action.
15. The tangible computer readable storage device or storage disk of claim 14 , wherein the instructions cause the first device to initiate a second action on the second device.
16. The tangible computer readable storage device or storage disk of claim 14 , wherein the instructions are further to cause the first device to detect a second monitoring code in the audio, the second monitoring code to be received after the monitoring code, the instructions further to cause the first device to generate the signature based on an audio portion located before the second monitoring code.
17. The tangible computer readable storage device or storage disk of claim 14 , wherein the audio further includes a source identification code indicating a source of the audio, the instructions to cause the first device to generate the signature based on the source identification code.
18. The tangible computer readable storage device or storage disk of claim 14 , wherein the instructions are further to cause the first device to generate a plurality of signatures at time intervals in response to the monitoring code being located in the audio.
19. The tangible computer readable storage device or storage disk of claim 14 , wherein the action includes at least one of displaying an image, displaying text, displaying a web page, playing a video, playing audio, or executing software on the second device.
