Abstract
Methods and apparatus for crediting a media presentation device are disclosed. An example method includes detecting whether encoded information is present in audio obtained from a media device during a time period. Determining an on/off state of the media device based on a gain level applied by an automatic gain controller during collection of the audio. Crediting the media device with presenting media during the time period when the encoded information is detected irrespective of the on/off state determined for the media device, and not crediting the media device with presenting the media during the time period when the encoded information is not detected and the on/off state determined for the media device is an off state.
