ABSTRACT:
An apparatus and method for processing audience measurement data detects and corrects one or more corrupted time codes. The corrupted time codes are identified by calculating a first set of intervals between a set of read times that may, but need not, be consecutive, each of which corresponds to one of the time codes extracted from a broadcast signal. The first set of intervals are compared to a second set of intervals between the time codes to identify when one or more of the second intervals do not meet a predetermined criteria. At least one of the time codes associated with each of the second intervals that do not meet the criteria is identified as being corrupted. The method used to calculate a corrected time code involves using the magnitude of the corresponding first interval to calculate the corrected time code.
