Abstract: Systems, methods, and apparatus to identify linear and non-linear media presentations are disclosed. An example method to determine whether a media presentation is a linear or a non-linear media presentation comprises generating a reference log comprising a first media identifier of first media and a time at which the first media was presented, accessing a media presentation log comprising a second media identifier of second media and a time at which the second media was presented, and determining whether the second media correspond to a linear media presentation or a non-linear media presentation by comparing the media presentation log to the reference log.

Abstract: Methods and apparatus for identifying media are described. An example apparatus includes at least one memory, instructions in the apparatus; and processor circuitry to execute the instructions to: determine application identification information for a media presentation application executing on a media device; determine a first watermark for the application identification information from a lookup table; request media identification information for media from the media presentation application; determine a second watermark for the media identification information from the lookup table; insert the first watermark in the media prior to output of the media by the media device; and insert the second watermark in the media prior to the output of the media by the media device.
