Methods and systems for reducing crediting errors due to spillover using audio codes and/or signatures
First Claim
1. A method to reduce crediting errors due to spillover in a media measuring system, comprising:
- determining if first media monitoring data provided from a first meter identifies a same media as second media monitoring data provided from a second meter, the first meter and the second meter to monitor presented media at respective different locations;
if the first media monitoring data identifies the same media as the second media monitoring data, detecting if spillover occurred by determining if an absolute value of a difference between a first timestamp associated with the first media monitoring data and a second timestamp associated with the second media monitoring data is less than a threshold; and
if spillover occurred, determining which of the first media monitoring data or the second media monitoring data to credit as a media exposure.

Abstract
Methods, apparatus, and articles of manufacture for reducing exposure crediting errors due to spillover in a media monitoring system are disclosed. An example method includes determining if first media monitoring data provided from a first meter identifies a same media as second media monitoring data provided from a second meter. If the first media monitoring data identifies the same media as the second media monitoring data, the example method includes detecting if spillover occurred by determining if an absolute value of a difference between a first timestamp associated with the first media monitoring data and a second timestamp associated with the second media monitoring data is less than a threshold. If spillover occurred, the example method includes determining which of the first media monitoring data or the second media monitoring data to credit as a media exposure.

11. A spillover manager to reduce crediting errors due to spillover in a media measuring system, comprising:
-
a media comparator to; determine if first media detected by a first meter is equivalent to second media detected by a second meter, the first meter and the second meter to monitor presented media at different locations; and if the first media is not equivalent to the second media, determine that spillover did not occur; and a timestamp comparator to determine whether spillover occurred by determining if an absolute value of a difference between a first timestamp associated with the first media detected by the first meter and a second timestamp associated with the second media detected by the second meter is less than a threshold and to determine which of the first media or the second media to credit as a media exposure. - View Dependent Claims (12, 13, 14, 15, 16, 17, 18, 19, 20)

21. A tangible computer readable storage medium comprising instructions that, when executed, cause a computing device to at least:
-
determine if first media monitoring data provided from a first meter identifies a same media as second media monitoring data provided from a second meter, the first meter and the second meter to monitor presented media at respective different locations; if the first media monitoring data identifies the same media as the second media monitoring data, detect if spillover occurred by determining if an absolute value of a difference between a first timestamp associated with the first media monitoring data and a second timestamp associated with the second media monitoring data is less than a threshold; and if spillover occurred, determine which of the first media monitoring data or the second media monitoring data to credit as a media exposure. - View Dependent Claims (22, 23, 24, 25, 26, 27, 28, 29, 30)
