Activating functions in processing devices using start codes embedded in audio
View Patent ↗Apparatus, system and method for performing an action such as accessing supplementary data and/or executing software on a device capable of receiving multimedia are disclosed. After multimedia is received, a monitoring code is detected and a signature is extracted in response thereto from an audio portion of the multimedia. The ancillary code includes a plurality of code symbols arranged in a plurality of layers in a predetermined time period, and the signature is extracted from features of the audio of the multimedia. Supplementary data is accessed and/or software is executed using the detected code and/or signature.
1. A method of performing an action in a device based on receipt of and/or exposure to audio, comprising:
receiving audio at the device, the audio having a monitoring code indicating that the audio is to be monitored;
in response to detection of the monitoring code, generating a signature based on the audio using at least a portion of the audio containing the monitoring code; and
causing the performance of the action at least in part by the device based on at least one of the monitoring code or the signature.
2. The method of claim 1 , wherein the monitoring code comprises a plurality of substantially single-frequency code components.
3. The method of claim 2 , wherein generating the signature comprises one of (a) generating a signature data set reflecting time-domain variations of the received audio in a plurality of frequency sub-bands of the received audio, or (b) generating a signature data set reflecting frequency-domain variations in the received audio.
4. The method according to claim 1 , wherein the action comprises presenting at least one of video, audio, images, HyperText Markup Language (HTML) content, a Uniform Resource Locator (URL), a shortened URL, metadata, or text.
5. The method according to claim 1 , wherein the action comprises activating software on the device.
6. The method according to claim 1 , wherein the action comprises processing at least one of the monitoring code or the signature on the device.
7. The method according to claim 1 , wherein the action comprises transmitting at least one of the monitoring code or the signature from the device for processing, and receiving data in the device generated based on the processing.
8. The method according to claim 1 , wherein the device comprises at least one of a cell phone, a smart phone, a personal digital assistant, a personal computer, a portable computer, a television, a set-top box, or a media box.
9. A method of performing an action in a processing device based on receipt of and/or exposure to audio, comprising:
detecting a monitoring code in received audio, the monitoring code indicating that the audio is to be monitored;
generating a signature in response to detection of the monitoring code, the signature representative of the audio, the signature generated based on at least a portion of the audio containing the monitoring code; and
performing the action with the device based on at least one of the monitoring code or the signature.
10. The method according to claim 9 , wherein the action comprises processing at least one of the monitoring code or the signature on the device to at least one of execute a link, present media, display a web page, or activate software.
11. The method according to claim 9 , wherein the action comprises transmitting at least one of the monitoring code or the signature from the device for processing, and receiving data in the device generated based on the processing.
12. A processing device to perform an action based on receipt of and/or exposure to audio, the processing device comprising:
an input device to receive audio carrying a monitoring code indicating that the audio is to be monitored; and
a processor to detect the monitoring code and, in response to detection of the monitoring code, generate a signature characterizing the audio using at least a portion of the audio containing the monitoring code, wherein the processor is to cause the performance of the action based on at least one of the monitoring code or the signature.
13. The processing device of claim 12 , wherein the monitoring code comprises a plurality of substantially single-frequency code components.
14. The processing device of claim 13 , wherein the processor is to generate the signature by one of (a) generating a signature data set reflecting time-domain variations of the received audio data in a plurality of frequency sub-bands of the received audio, or (b) generating a signature data set reflecting frequency-domain variations in the received audio.
15. The processing device according to claim 12 , wherein the action comprises presenting at least one of one of video, audio, images, HyperText Markup Language (HTML) content, a Uniform Resource Locator (URL), a shortened URL, metadata, or text.
16. The processing device according to claim 12 , wherein the action comprises activating software on the device.
17. The processing device according to claim 12 , wherein the action comprises processing at least one of the monitoring code or the signature on the device to at least one of execute a link, present media, display a web page, or activate software.
18. The processing device according to claim 12 , further comprising an output device, wherein the action comprises transmitting at least one of the monitoring code or the signature from the device using the output device, and the input device is to receive data generated based on processing of the monitoring code or the signature which occurs separate from the device.
19. The processing device according to claim 12 , wherein the processing device comprises at least one of a cell phone, a smart phone, a personal digital assistant, a personal computer, a portable computer, a television, a set-top box, and a media box.
20. The method according to claim 9 , wherein the action comprises presenting at least one of video, audio, images, HyperText Markup Language (HTML) content, a Uniform Resource Locator (URL), a shortened URL, metadata, text or activating software on the device.
