Audio watermarking for people monitoring
Methods, apparatus, systems and articles of manufacture (e.g., physical storage media) to utilize audio watermarking for people monitoring are disclosed. Example people monitoring methods disclosed herein include determining, at a user device, whether a first trigger condition for emitting an audio watermark identifying at least one of the user device or a user of the user device is satisfied. Such example methods also include, in response to determining that the first trigger condition is satisfied, providing a first audio signal including the audio watermark to an audio circuit that is to output an acoustic signal from the user device.
1. An apparatus to trigger a targeted advertisement, the apparatus comprising:
a meter to:
obtain audio data via a microphone at a media presentation location;
detect a watermark in the audio data;
classify the watermark into at least one of a media watermark classification or a people monitoring watermark classification; and
in response to classification of the watermark into the people monitoring watermark classification:
identify a trigger condition corresponding to the watermark; and
send, via a network, audience data to a data processing facility, the audience data including information to indicate the trigger condition corresponding to the watermark, the audience data to cause transmission of the targeted advertisement via the network to the media presentation location; and
a media presentation device at the media presentation location to present the targeted advertisement to an audience corresponding to the audience data.
2. The apparatus as defined in claim 1 , wherein the meter is to determine the trigger condition corresponds to a first geographic area.
3. The apparatus as defined in claim 2 , wherein the targeted advertisement is selected based on the first geographic area.
4. The apparatus as defined in claim 1 , wherein the meter is to determine the trigger condition corresponds to a first time period.
5. The apparatus as defined in claim 4 , wherein the targeted advertisement is selected based on the first time period.
6. The apparatus as defined in claim 1 , wherein the audio data is based at least in part on first media content presented on the media presentation device at a first time.
7. The apparatus as defined in claim 6 , wherein the media presentation device is to present the targeted advertisement at a second time, the second time after the first time.
8. The apparatus as defined in claim 1 , wherein the media presentation device includes at least one of a television, a multimedia computer system, or a wireless telephone.
9. The apparatus as defined in claim 1 , wherein the watermark includes codes.
10. A system to present a targeted advertisement at a monitored site, the system comprising:
means for reporting audience data, the reporting means to:
detect a watermark in audio data acquired at the monitored site;
classify the watermark into at least one of a media watermark classification or a people monitoring watermark classification; and
in response to classification of the watermark into the people monitoring watermark classification:
identify a trigger condition associated with the watermark; and
send, via a network, the audience data to a data processing facility, the audience data including information to indicate the trigger condition associated with the watermark, the audience data to cause the targeted advertisement to be presented to the monitored site, the targeted advertisement transmitted via the network and associated with the audience data; and
means for presenting media at the monitored site, the presenting means to present the targeted advertisement to an audience corresponding to the audience data.
11. The system as defined in claim 10 , wherein the reporting means is to determine the trigger condition corresponds to a first geographic area.
12. The system as defined in claim 11 , wherein the reporting means is to determine the trigger condition corresponds to a first time period.
13. The system as defined in claim 10 , wherein the reporting means is to acquire the audio data via a microphone during a first time, the audio data based at least in part on first media presented on the presenting means.
14. The system as defined in claim 13 , wherein the presenting means is to present the targeted advertisement as second media during a second time occurring after the first time.
15. The system as defined in claim 10 , wherein the presenting means includes at least one of a television, a multimedia computer system, or a wireless telephone.
16. A tangible machine readable storage medium comprising machine readable instructions that, when executed, cause a processor to at least:
obtain audio data via a microphone;
detect a watermark in the audio data;
classify the watermark into at least one of a media watermark classification or a people monitoring watermark classification; and
in response to classification of the watermark into the people monitoring watermark classification:
identify a trigger condition corresponding to the watermark; and
send, via a network, audience data to a data processing facility, the audience data including information to indicate the trigger condition corresponding to the watermark, the audience data to cause transmission of a targeted advertisement via the network, the targeted advertisement to be presented on a media presentation device, the targeted advertisement associated with the audience data.
17. The tangible machine readable storage medium as defined in claim 16 , wherein the instructions, when executed, cause the processor to identify the trigger condition corresponds to a first geographic area associated with the audience data.
18. The tangible machine readable storage medium as defined in claim 17 , wherein the targeted advertisement is selected based on the first geographic area.
19. The tangible machine readable storage medium as defined in claim 16 , wherein the instructions, when executed, cause the processor to identify the trigger condition corresponds to a first time period.
20. The tangible machine readable storage medium as defined in claim 19 , wherein the targeted advertisement is selected based on the first time period.
21. The tangible machine readable storage medium as defined in claim 16 , wherein the audio data is based at least in part on first media content presented on the media presentation device at a first time.
22. The tangible machine readable storage medium as defined in claim 21 , wherein the media presentation device is to present the targeted advertisement at a second time, the second time after the first time.
23. The tangible machine readable storage medium as defined in claim 16 , wherein the instructions, when executed, cause the processor to identify at least one of codes or auxiliary codes within the watermark.
