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.

2. An apparatus for use with a set-top box (STB) and a media presentation device, comprising:
-
means for interfacing an input to receive a first audio signal associated with a program selected by a user via the STB; means for transducing to receive a free-field radiating second audio signal output by at least one of the media presentation device or an audio system associated with the media presentation device; means for filtering having adaptive coefficients to delay and to attenuate the first audio signal to form an estimate of the second audio signal; means for comparing to compare the second audio signal to the estimate of the second audio signal to form an output; means for protecting privacy to facilitate burst mode operation of the means for comparing by periodically disabling the means for transducing and the means for comparing; and means for interfacing an output to provide a value indicative of whether the program selected by the user via the STB is presented at the media presentation device based on the output. - View Dependent Claims (3, 4, 5, 6, 7, 8, 9, 10, 11, 12)

13. An apparatus for use with a set-top box (STB) and a media presentation device comprising:
-
means for interfacing an input to receive a first audio signal associated with a program selected by a user via the STB; means for transducing to receive a free-field radiating second audio signal output by at least one of the media presentation device or an audio system associated with the media presentation device; means for comparing to compare the second audio signal to the first audio signal to form an output; means for interfacing an output to provide a value indicative of whether the program selected by the user via the STB is presented at the media presentation device based on the output; and means for protecting privacy comprising means for timing to facilitate burst mode operation of the comparing means by periodically disabling the transducing means and the comparing means. - View Dependent Claims (14)

15. An apparatus to generate media presentation information, the apparatus comprising:
-
means for comparing to periodically output a value indicative of whether media selected via a set-top box is presented at a media presentation location, by the means for comparing comparing a first audio signal associated with media of a media presentation device to ambient audio received in the media presentation location via an audio system associated with the media presentation device; means for protecting privacy to facilitate operation of the means for comparing by periodically preventing the means for comparing from receiving the ambient audio from a means for transducing for a first time period based on a granularity of the media presentation information that is to be reported, the granularity based on an amount of time, and enabling the means for comparing to receive the ambient audio from the means for transducing after the first time period expires; and means for metering to record presentation of the media based on the output. - View Dependent Claims (16)

17. An apparatus to generate media presentation information, the apparatus comprising:
-
means for comparing 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; means for protecting privacy to facilitate operation of the comparing means by periodically preventing the comparing means from receiving the ambient audio from means for transducing for a first time period based on a granularity of the media presentation information that is to be reported, the granularity based on an amount of time, and enabling the comparing means to receive the ambient audio from the transducing means after the first time period expires; means for metering to record presentation of the media based on the output; means for filtering to form an estimate of the ambient audio by delaying and attenuating the first audio signal, and the comparing means to compare the estimate of the ambient audio to the ambient audio to form the output, wherein the filtering means to have adaptive weights to delay and to attenuate the first audio signal. - View Dependent Claims (18, 19, 20, 21)
