Systems and methods to wirelessly meter audio/visual devices
View Patent ↗Example systems and methods to wirelessly meter audio/visual (A/V) devices are disclosed. A disclosed example method receives media content from an A/V source device, embeds a video overlay in the wirelessly received media content, and wirelessly transmits the media content and the video overlay to the wireless A/V device. The example method wirelessly receives audience identification information in response to the transmitted video overlay, and wirelessly receives audience behavior information.
1. A method to identify a source of media activity, comprising:
embedding, at a household, a first watermark in media received from a household media device;
wirelessly retransmitting the media with the first watermark to a portable television via a wireless access point at the household;
acoustically receiving audio-based media emanating from the portable television at the household; and
determining whether the audio-based media acoustically received from the portable television is sourced from the household media device or a local television station based on whether the audio-based media includes the first watermark embedded at the household.
2. A method as defined in claim 1 , wherein the media comprises an audio/visual (A/V) signal having an audio portion and a video portion.
3. A method as defined in claim 2 , wherein the A/V signal is at least one of a set-top box A/V signal, a video game console A/V signal, a video cassette recorder (VCR) A/V signal, a digital video recorder (DVR) A/V signal, or a digital versatile disk (DVD) A/V signal.
4. A method as defined in claim 2 , wherein the A/V signal is converted to a radio frequency (RF) signal.
5. A method as defined in claim 4 , wherein the RF signal is transmitted as an 802.11 compliant signal.
6. A method as defined in claim 1 , further comprising detecting a second watermark in the retransmitted media, the second watermark associated with broadcaster generated media identification information.
7. A method as defined in claim 1 , further comprising ignoring the audio-based media emanating from the portable television when the first watermark is absent.
8. A tangible machine readable storage device or storage disk comprising machine accessible instructions that, when executed, cause a machine to, at least:
embed, at a household, a first watermark in media received from a media device located at the household;
wirelessly retransmit the first media and the first watermark to a portable television via a wireless access point at the household;
acoustically receive audio-based media emanating from the portable television at the household; and
determine whether the audio-based media acoustically received from the portable television is sourced from the household media device or a source external to the household based on whether the audio-based media includes the first watermark embedded at the household.
9. A machine readable storage device or storage disk as defined in claim 8 , wherein the machine accessible instructions further cause the machine to receive the media as an audio/visual (A/V) signal having an audio portion and a video portion.
10. A machine readable storage device or storage disk as defined in claim 9 , wherein the machine accessible instructions further cause the machine to receive the A/V signal as at least one of a set-top box A/V signal, a video game console A/V signal, a video cassette recorder (VCR) A/V signal, a digital video recorder (DVR) A/V signal, or a digital versatile disk (DVD) A/V signal.
11. A machine readable storage device or storage disk as defined in claim 9 , wherein the machine accessible instructions further cause the machine to convert the A/V signal to a radio frequency (RF) signal.
12. A machine readable storage device or storage disk as defined in claim 9 , wherein the machine accessible instructions further cause the machine to transmit a radio frequency (RF) signal as an 802.11 compliant signal.
13. A machine readable storage device or storage disk as defined in claim 8 , wherein the machine accessible instructions further cause the machine to detect a second watermark in the audio-based media emanating from the portable television, the second watermark associated with broadcaster generated media identification information.
14. A machine readable storage device or storage disk as defined in claim 8 , wherein the machine accessible instructions further cause the machine to ignore the audio-based media emanating from the portable television when the first watermark is absent.
15. A system to distinguish media from a household media source from media from an external media source, comprising:
a wireless interface to embed, at a household, a watermark in media received from a household media device, and to wirelessly retransmit the watermark and the media from a transmission point within the household and to a portable television also within the household; and
a mobile device interface to acoustically receive audio-based media emanating from the portable television within the household and, to determine whether the audio-based media acoustically received from the portable television is sourced from the household media device or the external media source based on whether the audio-based media includes the first watermark which was embedded at the household.
16. A system as defined in claim 15 , wherein the household media device provides the media and comprises at least one of a set-top box, a video game console, a digital versatile disk (DVD) player, a digital video recorder (DVR), or a video cassette recorder (VCR).
17. A system as defined in claim 15 , wherein the wireless interface comprises a radio frequency (RF) receiver to receive a signal indicative of audience member identity.
18. A system as defined in claim 15 , wherein the wireless interface comprises a wireless access point to convert the media to a radio frequency (RF) signal.
19. A system as defined in claim 15 , wherein the mobile device interface comprises a microphone to receive an audio signal from the portable television.
20. A system as defined in claim 19 , wherein the mobile device interface comprises an infra-red (IR) receiver to receive an IR signal from an audience remote control.
21. A system as defined in claim 20 , wherein the mobile device interface comprises a radio frequency (RF) modulator to modulate at least one of the audio signal or the IR signal to an RF signal.
22. A system as defined in claim 15 , wherein the wireless interface comprises a wireless microphone receiver to receive a radio frequency (RF) signal from the mobile device interface.
23. A system as defined in claim 22 , wherein the wireless microphone receiver comprises an RF demodulator to demodulate the received RF signal, the demodulated signal to be transmitted to a data acquisition interface.
24. A system as defined in claim 15 further comprising a central data store to receive audience behavior data from a data acquisition interface.
25. A system as defined in claim 15 wherein the wireless interface comprises one or more of a wireless access point, a wireless user identifier (WUI), and a wireless microphone receiving device.
26. A system as defined in claim 25 wherein the wireless access point comprises a transmitter and receiver to transmit and receive audio-visual signals via an 802.11-type format.
27. A system as defined in claim 25 wherein the WUI comprises at least one of a radio frequency (RF) receiver, or an RF to infra-red (IR) converter.
28. A system as defined in claim 27 , wherein the WUI is a peoplemeter.
