Abstract
Methods, apparatus, systems and articles of manufacture to monitor media are disclosed. An example apparatus includes an orderer to order metadata according to timing information, the metadata corresponding to digital media from a media provider; a data shifter to adjust the ordered metadata using a plurality of offsets to generate a plurality of adjusted ordered metadata; a comparator to perform a plurality of comparisons by comparing the plurality of adjusted ordered metadata to reference data; and compute a plurality of errors corresponding to the plurality of comparisons; and the data shifter to identify an offset of the plurality of offsets corresponding to a lowest computed error of the plurality of errors; and adjust the ordered metadata using the offset.
