Abstract

Example methods and apparatus to verify presentation of media content are disclosed. A disclosed example apparatus for generating media presentation information includes a comparator to periodically output a value indicative of whether media selected via a set-top box is presented at a media presentation location by comparing a first audio signal associated with the media to ambient audio received in the media presentation location via an audio system associated with a media presentation device. The example apparatus also includes a privacy protector to facilitate operation of the comparator by periodically preventing the comparator from receiving of the ambient audio. The example apparatus also includes a metering module to record presentation of the media based on the output.

Claims

1. An apparatus to generate media presentation information, the apparatus comprising:

a comparator to periodically output a value indicative of whether media selected via a set-top box is presented at a media presentation location by comparing a first audio signal associated with the media to ambient audio received in the media presentation location via an audio system associated with a media presentation device;

a privacy protector to facilitate operation of the comparator by periodically preventing the comparator from receiving of the ambient audio; and

a metering module to record presentation of the media based on the output.

2. An apparatus as defined in claim 1, further including:

a transducer to receive the ambient audio in the media presentation location, and

the privacy protector to include a timer to facilitate the operation of the comparator by periodically disabling the transducer.

3. An apparatus as defined in claim 1, further including:

a filter to form an estimate of the ambient audio by delaying and attenuating the first audio signal, and

the comparator to compare the estimate of the ambient audio to the ambient audio to form the output.

4. An apparatus as defined in claim 3, wherein the filter to have adaptive weights to delay and to attenuate the first audio signal.

5. An apparatus as defined in claim 4, wherein the filter is to set the adaptive weights to zero when the receiving of the ambient audio is enabled.

6. An apparatus as defined in claim 3, wherein the comparator is to form the output by:

subtracting the estimate of the ambient audio from the ambient audio to form a residual signal; and

comparing the residual signal to a threshold.

7. An apparatus as defined in claim 3, wherein the output represents whether the estimate of the ambient audio is present in the ambient audio.

8. A method to generate media presentation information, the method comprising:

comparing, via a comparator, a first audio signal associated with media to ambient audio received in a media presentation location via an audio system associated with a media presentation device to form an output;

implementing a privacy protocol by periodically disabling the receiving of the ambient audio; and

in response to the output, recording presentation of the media.

9. An apparatus as defined in claim 8, further including:

receiving, at a transducer, the ambient audio in the media presentation location, and

wherein the implementing of the privacy protocol includes;

disabling the transducer from the receiving of the ambient audio;

initializing a timer; and

restarting the transducer receiving the ambient audio when the timer expires.

10. A method as defined in claim 8, further including:

forming an estimate of the ambient audio by delaying and attenuating the first audio signal; and

comparing the estimate of the ambient audio to the ambient audio to form the output.

11. A method as defined in claim 10, wherein the delaying and the attenuating of the first audio signal includes applying a filter having adaptive weights to the first audio signal.

12. A method as defined in claim 11, further including setting the adaptive weights to zero when the receiving of the ambient audio is enabled.

13. A method as defined in claim 10, wherein the forming of the output includes:

subtracting the estimate of the ambient audio from the ambient audio to form a residual signal; and

comparing the residual signal to a threshold.

14. A method as defined in claim 10, wherein the output represents whether the estimate of the ambient audio is present in the ambient audio.

15. A tangible machine-readable storage device or storage disk comprising instructions which, when executed, cause a machine to at least:

compare a first audio signal associated with media to ambient audio received in a media presentation location via an audio system associated with a media presentation device to form an output;

implement a privacy protocol by periodically disabling the receiving of the ambient audio; and

record presentation of the media based on the output.

16. A machine-readable storage device or storage disk as defined in claim 15, wherein the machine-readable instructions, when executed, cause the machine to:

receive, at a transducer, the ambient audio in the media presentation location; and

implement the privacy protocol by;

disabling the transducer from the receiving of the ambient audio;

initializing a timer; and

restarting the transducer receiving the ambient audio when the timer expires.

17. A machine-readable storage device or storage disk as defined in claim 15, wherein the machine-readable instructions, when executed, cause the machine to:

form an estimate of the ambient audio by delaying and attenuating the first audio signal; and

compare the estimate of the ambient audio to the ambient audio to form the output.

18. A machine-readable storage device or storage disk as defined in claim 17, wherein the machine-readable instructions, when executed, cause the machine to apply a filter having adaptive weights to the first audio signal to delay and to attenuate the first audio signal.

19. A machine-readable storage device or storage disk as defined in claim 18, wherein the machine-readable instructions, when executed, cause the machine to set the adaptive weights to zero when the receiving of the ambient audio is enabled.

20. A machine-readable storage device or storage disk as defined in claim 17, wherein the machine-readable instructions, when executed, cause the machine to:

subtract the estimate of the ambient audio from the ambient audio to form a residual signal; and

compare the residual signal to a threshold to form the output, the output representing whether the estimate of the ambient audio is present in the ambient audio.
