<p>Example methods disclosed herein to identify media sources comprise obtaining monitored signatures generated from monitored media, comparing the monitored signatures with reference signatures generated from reference media provided by a plurality of reference sources, determining tracking segments associated with respective ones of the reference sources, each tracking segment representing sequences of matches between the monitored signatures and respective reference signatures for a respective one of the reference sources, and evaluating time lengths of the tracking segments to identify which reference source in the plurality of reference sources provided the monitored media.</p> |
