Methods and apparatus for using location information to manage spillover in an audience monitoring system
View Patent ↗Methods, apparatus, and articles of manufacture for using location information to manage spillover in an audience monitoring system are disclosed. An example method involves identifying a first location of a portable metering device at a first time based on a plurality of location coordinates received from a location information system. The example method also involves generating media monitoring information corresponding to a media signal received at the first time. Additionally, the example method involves identifying the media monitoring information as being associated with a spillover signal in response to determining that a media delivery device is not located at the first location of the portable metering device at the first time.
1. A method of detecting spillover, the method comprising:
identifying, by executing an instruction with a processor, a first location of a portable metering device at a first time based on a plurality of location coordinates received from a location information system;
generating, by executing an instruction with the processor, 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, media delivery device separate from the portable metering device;
identifying, by executing an instruction with the processor, 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
disregarding, by executing an instruction with the processor, 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.
2. The method as defined in claim 1 , wherein the spillover signal is indicative of media presented in a second location and detected by the portable metering device located in the first location, and the media monitoring information being associated with the spillover signal indicates that an audience member associated with the portable metering device was not sufficiently exposed to the media to indicate consumption of the media by the audience member.
3. The method as defined in claim 1 , further including obtaining, by executing an instruction with the processor, a time stamp associated with the media signal when the media signal is received by the portable metering device.
4. The method as defined in claim 1 , wherein the identifying of the first location of the portable metering device at the first time further includes comparing the plurality of location coordinates received from the location information system to a coordinate map of a household in which the media delivery device is located, the coordinate map identifying the first location.
5. The method as defined in claim 1 , wherein the first location of the portable metering device is an outdoor location.
6. 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.
7. The portable metering device as defined in claim 6 , wherein the spillover signal is indicative of media presented in a second location and detected by the portable metering device located in the first location, and the media monitoring information being associated with the spillover signal indicates that an audience member associated with the portable metering device was not sufficiently exposed to the media to indicate consumption of the media by the audience member.
8. The portable metering device as defined in claim 6 , wherein the processor is further to obtain a time stamp associated with the media signal when the media signal is received by the portable metering device.
9. The portable metering device as defined in claim 6 , wherein to identify the first location of the portable metering device at the first time, the processor is further to compare the plurality of location coordinates received from the location sensor to a coordinate map of a household in which the media delivery device is located, the coordinate map identifying the first location.
10. The portable metering device as defined in claim 6 , wherein the first location is an outdoor location.
11. 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.
12. The non-transitory computer readable medium as defined in claim 11 , wherein the spillover signal is indicative of the media presented in a second location and detected by the portable metering device located in the first location, and the media monitoring information being associated with the spillover signal indicates that an audience member associated with the portable metering device was not sufficiently exposed to the media presentation to indicate consumption of the media presentation.
13. The non-transitory computer readable medium as defined in claim 11 , having instructions stored thereon that, when executed, cause the portable metering device to obtain a time stamp associated with the media signal when the media signal is received by the portable metering device.
14. The non-transitory computer readable medium as defined in claim 11 , wherein to identify the first location of the portable metering device at the first time, the instructions, when executed, cause the portable metering device to compare the plurality of location coordinates received from the location sensor to a coordinate map of a household in which the media delivery device is located, the coordinate map identifying the first location.
15. The non-transitory computer readable medium as defined in claim 11 , wherein the first location is an outdoor location.
