Methods and apparatus to discriminate between linear and non-linear media

摘要

Methods and apparatus to discriminate between linear and non-linear media 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.

1. A method to automatically determine whether a media presentation is a linear media presentation or a non-linear media presentation, the method comprising:
generating, by executing an instruction with a processor, a reference log including first media identifiers of first media and first times at which the first media was presented as a linear media presentation; receiving, at the processor, at least one of an audio fingerprint or a watermark code generated by a media monitoring device electronically monitoring the media presentation of second media, the audio fingerprint based on an audio characteristic of the second media electronically measured at discrete times by the media monitoring device; identifying, by executing an instruction with the processor, second media identifiers of the second media from the at least one of the audio fingerprint or the watermark code by matching the at least one of the audio fingerprint or the watermark code to a reference audio fingerprint or a reference watermark code in a reference database; generating, by executing an instruction with the processor, a media presentation log for the media presentation, the media presentation log including the second media identifiers of the second media and second times at which the second media was presented; comparing, by executing an instruction with the processor, the media presentation log to the reference log to determine a number of matches between ones of the first media identifiers and ones of the second media identifiers, the matches between the ones of the first media identifiers and the ones of the second media identifiers being in a same order in the media presentation log and in the reference log; and classifying, by executing an instruction with the processor, the media presentation of the second media as a linear media presentation when the number of matches satisfies a threshold.
