Methods and systems for reducing spillover by detecting signal distortion
First Claim
1. A method to credit media presented by a media presentation device, the method comprising:
- determining, via a processor, an actual frequency spectrum of the media monitored by a meter;
determining, via the processor, absolute values of differences between amplitudes of corresponding frequency components of the actual frequency spectrum and an expected frequency spectrum, the expected frequency spectrum stored in a database in association with a media identifier corresponding to the media;
determining, via the processor, whether spillover occurred based on a summation of the absolute values satisfying a threshold; and
crediting, via the processor, the media with a media exposure if spillover did not occur.

Abstract
Methods, apparatus, and articles of manufacture for reducing spillover in a media monitoring system are disclosed. An example method includes determining an actual frequency spectrum of the media monitored by a meter, and determining absolute values of differences between amplitudes of corresponding frequency components of the actual frequency spectrum and an expected frequency spectrum, the expected frequency spectrum stored in a database in association with a media identifier corresponding to the media. An example method also includes determining whether spillover occurred based on a summation of the absolute values satisfying a threshold, crediting the media with a media exposure if spillover did not occur.
