摘要

Example methods disclosed herein to identify media sources include determining whether a first time difference between a first meter signature and a second meter signature associated with presented media is equivalent to a second time difference between a first reference signature determined to match the first meter signature and a second reference signature determined to match the second meter signature, the first and second reference signatures being associated with a first one of a plurality of media sources. Such example methods also include, in response to determining that the first time difference and the second time difference are equivalent, appending the second reference signature to a first tracking segment associated with the first one of the media sources to cause a first time length associated with the first tracking segment to be increased based on at least a respective timestamp associated with the second reference signature.

1. A method to identify media sources, the method comprising:
comparing, with a processor, meter signatures generated from presented media with reference signatures generated from reference media provided by a plurality of media sources, the meter signatures and the reference signatures having respective timestamps; determining, with the processor, whether a first time difference between a first meter signature and a second meter signature is equivalent to a second time difference between a first reference signature determined to match the first meter signature and a second reference signature determined to match the second meter signature, the first and second reference signatures being associated with a first one of the media sources; in response to determining that the first time difference and the second time difference are equivalent, appending, with the processor, the second reference signature to a first tracking segment associated with the first one of the media sources to cause a first time length associated with the first tracking segment to be increased based on a respective timestamp associated with the second reference signature; and evaluating, with the processor, the first time length to determine whether the first one of the media sources provided the presented media.
