Methods and apparatus to adjust signature matching results for audience measurement
First Claim
1. A method for monitoring a media presentation, the method comprising:
- obtaining, from a monitoring device, a first signature representative of the monitored media presentation;
obtaining, from the monitoring device, an environmental characteristic associated with the first signature; and
adjusting a signature matching rate, which corresponds to a number of times signatures obtained from the monitoring device are determined to match corresponding reference signatures representative of first reference media during a measurement time interval, using a first adjustment value when the first signature is determined to match a first reference signature representative of the first reference media, the first adjustment value being selected from a plurality of adjustment values based on the matched first reference media and the environmental characteristic.

Abstract
Methods and apparatus to adjust signature matching results for audience measurement are disclosed. An example method to adjust a signature matching result associated with monitoring a media presentation disclosed herein comprises obtaining, from a monitoring device, an audio signature representative of the monitored media presentation, obtaining, from the monitoring device, an environmental characteristic associated with the audio signature, and adjusting the signature matching result using an adjustment value when the audio signature is determined to match a reference signature representative of reference media, the adjustment value being selected from a plurality of adjustment values based on the matched reference signature and the environmental characteristic.

6. A method for monitoring a media presentation, the method comprising:
-
presenting reference media in a controlled environment having a first configuration setting from a plurality of possible configuration settings; determining a set of test signatures by monitoring the presentation of the reference media in the controlled environment; counting a number of successful matches between the set of test signatures and a respective set of reference signatures representative of the reference media to determine an adjustment value; storing the adjustment value in memory for subsequent selection to adjust a signature matching result, the adjustment value to be selected when an environmental characteristic associated with a first signature representative of the monitored media presentation corresponds to the first configuration setting; obtaining, from a monitoring device, the first signature representative of the monitored media presentation; obtaining, from the monitoring device, the environmental characteristic associated with the first signature; and adjusting the signature matching result using the adjustment value when the first signature is determined to match a reference signature representative of the reference media, the adjustment value being selected from a plurality of adjustment values based on the matched reference signature and the environmental characteristic. - View Dependent Claims (7)

8. A tangible machine readable storage device or storage disk comprising machine readable instructions which, when executed, cause a machine to at least:
adjust a signature matching rate using a first adjustment value when a first signature representative of a monitored media presentation is determined to match a first reference signature representative of first reference media, the first adjustment value being selected from a plurality of adjustment values based on the matched first reference media and an environmental characteristic associated with the first signature representative of the monitored media presentation, the signature matching rate corresponding to a number of times signatures representative of the monitored media presentation are determined to match corresponding reference signatures representative of the first reference media during measurement time interval. - View Dependent Claims (9, 10)

11. A tangible machine readable storage device or storage disk comprising machine readable instructions which, when executed, cause a machine to at least:
-
present reference media in a controlled environment having a first configuration setting from a plurality of possible configuration settings; determine a set of test signatures by monitoring the presentation of the reference media in the controlled environment; count a number of successful matches between the set of test signatures matches and a respective set of reference signatures representative of the reference media to determine an adjustment value; and store the adjustment value in memory for subsequent selection to adjust a signature matching result, the adjustment value to be selected when an environmental characteristic associated with a first signature representative of a monitored media presentation corresponds to the first configuration setting; and adjust the signature matching result using the adjustment value when a first signature representative of the monitored media presentation is determined to match a reference signature representative of reference media, the adjustment value being selected from a plurality of adjustment values based on the matched reference signature and the environmental characteristic associated with the first signature.

12. An apparatus to adjust a signature matching rate associated with monitoring a media presentation, the apparatus comprising:
-
a signature comparator to compare a first signature representative of the monitored media presentation with a plurality of reference signatures representative of a plurality of reference media sources; and a match rate adjuster to adjust the signature matching rate using a first adjustment value when the first signature is determined to match a reference signature representative of a first reference media source from the plurality of reference media sources, the signature matching rate being representative of a frequency with which reference signatures representative of the first reference media source are successfully matched during a measurement time interval, the first adjustment value being selected based on the matched reference signature and a first environmental characteristic associated with the first signature, the first environmental characteristic and the first signature being obtained from a same monitoring device. - View Dependent Claims (13, 14, 15, 16, 17, 18, 19)
