Methods and apparatus for using location information to manage spillover in an audience monitoring system

A portable metering device to detect spillover, the apparatus portable metering device comprising:

• a location sensor to receive a plurality of location coordinates;
• and
• a processor to:
• identify a first location of the portable metering device at a first time based on the plurality of location coordinates obtained by the location sensor;
• generate media monitoring information corresponding to a media signal received by the portable metering device at the first time, the media signal associated with media presented at the first time by a media delivery device separate from the portable metering device;
• identify the media monitoring information as being associated with a spillover signal in response to determining that the media delivery device is not located at the first location of the portable metering device at the first time;
• and
• disregard the media monitoring information when the media monitoring information is associated with the spillover signal, the disregarding to improve an accuracy of a media exposure credit by excluding media monitoring information associated with spillover.

A non-transitory computer readable medium comprising instructions stored thereon that, when executed, cause a portable metering device to:

• identify a first location of the portable metering device at a first time based on a plurality of location coordinates received from a location information system;
• generate media monitoring information corresponding to a media signal received by the portable metering device at the first time, the media signal associated with media presented at the first time by a media delivery device separate from the portable metering device;
• identify the media monitoring information as being associated with a spillover signal in response to determining that the media delivery device is not located at the first location of the portable metering device at the first time;
• and
• disregard the media monitoring information when the media monitoring information is associated with the spillover signal, the disregarding to improve an accuracy of a media exposure credit by excluding media monitoring information associated with spillover.
