Abstract
Methods and apparatus for crediting a media presentation device are disclosed. An example method includes obtaining ambient audio of a location including a media presentation device during a time period, detecting encoded information present in the ambient audio, crediting a first portion of the time period for the media presentation device to first media based on the encoded information, determining an on/off state of the media presentation device for a second portion of the time period different than the first portion based on the ambient audio, and crediting the second portion of the time period based on the on/off state of the media presentation device.
