Methods and systems for reducing crediting errors due to spillover using audio codes and/or signatures

摘要

An example method includes determining if first media monitoring data provided by a first meter in a first location identifies a same media as second media monitoring data provided by a second meter in a second location. When the first and second media monitoring data identify the same media, the example includes determining whether spillover occurred based on a time difference between a first timestamp associated with the first media monitoring data and a second timestamp associated with the second media monitoring data. Based on an occurrence of the spillover, the first media monitoring data is stored as credited media monitoring data for the first location indicative of a media exposure to an audience at the first location, and the second media monitoring data is not stored as credited media monitoring data for the second location when the first timestamp is earlier than the second timestamp.

1. A method to reduce media measurement errors attributable to spillover detected by meters located in different monitored locations, comprising:
determining, with a processor, if first media monitoring data provided by a first meter in a first location identifies a same media as second media monitoring data provided by a second meter in a second location; when the first and second media monitoring data identify the same media, determining, with the processor, whether spillover occurred based on a time difference between a first timestamp associated with the first media monitoring data and a second timestamp associated with the second media monitoring data; and based on an occurrence of the spillover, storing, with the processor, the first media monitoring data as credited media monitoring data for the first location and not storing the second media monitoring data as credited media monitoring data for the second location when the first timestamp is earlier than the second timestamp, the credited media monitoring data for the first location indicative of a media exposure to an audience at the first location.
