Abstract:
1. An apparatus for processing audience measurement data, said audience measurement data including a plurality of sequential data records, each of said data records including a time code retrieved from a broadcast signal, and a read time that corresponds to said time code such that a set of first intervals between said read times are mathematically related to a corresponding set of second intervals between said time codes, provided that said time codes are not corrupted, said apparatus comprising: a data input port for receiving said plurality of data records; and a processor coupled to said data input port, said processor being adapted to determine the magnitudes of said first and second intervals, wherein said processor is adapted to compare magnitudes of said first and second intervals to identify one or more of said time codes that are corrupted and to identify one or more of said time codes that are not corrupted, and wherein said processor is further adapted to calculate a corrected time code for each said time code that is corrupted.
