Methods and apparatus to verify presentation of media content
First Claim
1. An apparatus to generate media presentation information, the apparatus comprising:
- a computer-implemented comparator to periodically output a value indicative of whether media selected via a set-top box is presented at a media presentation location, by the comparator 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;
a computer-implemented privacy protector to facilitate operation of the comparator by periodically preventing the comparator from receiving the ambient audio from a transducer 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 comparator to receive the ambient audio from the transducer after the first time period expires; and
a computer-implemented meter to record presentation of the media based on the output.

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.

7. A method to generate media presentation information, the method comprising:
-
comparing, by executing at least one or more first instructions on a processor, via a comparator, a first audio signal associated with media of a media presentation device to ambient audio received in a media presentation location via an audio system associated with a the media presentation device to form an output; implementing, by executing at least one or more second instructions on a processor, a privacy protocol by periodically disabling the receiving of the ambient audio from a transducer 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 receiving of the ambient audio from the transducer after the first time period expires; and in response to the output, recording, by executing at least one or more third instructions on a processor, presentation of the media. - View Dependent Claims (8)
