Abstract:
Example methods and apparatus to verify presentation of media content are disclosed. A disclosed example apparatus for use with a set-top box (STB) and a media presentation device includes an audio input interface to receive a first audio signal associated with a program selected by a user via the STB, a microphone 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, a comparator to compare the second audio signal to the first audio signal to form an output, and an output interface to provide a value indicative of whether the program selected by the user via the STB is presented at the media presentation device.
