View Patent ↗Example methods, apparatus, and articles of manufacture of a media presentation device is disclosed. The disclosed example includes an output device, an input to receive user input, and a monitor installed in the media presentation device at a time of manufacture of the media presentation device, the monitor provided to a manufacturer of the media presentation device by an audience measurement entity. The monitor to obtain demographic information of a user via the input and present an agreement to the user via the output device of the media presentation device. The monitor to enable collection of monitoring information when the agreement is accepted, prevent collection of monitoring information when the agreement is not accepted and collect monitoring information identifying at least one of a media presentation on the media presentation device or a user interaction with the media presentation device when the collection of the monitoring information is enabled.
1. A media presentation device comprising:
a first processor, wherein media is presented on the media presentation device by executing an instruction with the first processor;
a memory;
an output device;
an input to receive user input; and
a monitor installed in the media presentation device at a time of manufacture of the media presentation device, the monitor provided to a manufacturer of the media presentation device by an audience measurement entity, the monitor including:
a signal line interface to collect monitoring information, the signal line interface including a video-out line physically coupled to a video output of the media presentation device during installation of the monitor in the media presentation device, and an audio-out line physically coupled to an audio output of the media presentation device during the installation of the monitor in the media presentation device;
a second processor; and
a second memory, the second memory including machine readable instructions that, when executed by the second processor, cause the second processor to:
obtain demographic information of a user via the input;
present an agreement to the user via the output device of the media presentation device;
enable collection of monitoring information when the agreement is accepted;
not enable collection of the monitoring information when the agreement is not accepted; and
