Methods and apparatus to adjust signature matching results for audience measurement
First Claim
1. A method to adjust a signature matching result associated with monitoring a media presentation, the method comprising:
- obtaining a monitored signature representative of the monitored media presentation from a monitoring device;
obtaining an environmental characteristic associated with the monitored signature from the monitoring device; and
adjusting the signature matching result using an adjustment value when the monitored signature is determined to match a reference signature representative of reference media, the adjustment value selected from a plurality of adjustment values based on the matched reference signature and the environmental characteristic, wherein the monitored signature includes a video signature, and the environmental characteristic includes at least one of a brightness level or an ambient light level measured by the monitoring device.

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 content presentation disclosed herein comprises obtaining a monitored signature representative of the monitored media content presentation from a monitoring device, obtaining an environmental characteristic associated with the monitored signature from the monitoring device, and adjusting the signature matching result using an adjustment value when the monitored signature is determined to match a reference signature representative of reference media content, the adjustment value selected from a plurality of adjustment values based on the matched reference signature and the environmental characteristic.

11. A tangible machine readable storage medium, excluding propagating signals, and comprising machine readable instructions which, when executed, cause a machine to at least:
-
obtain a monitored signature representative of a monitored media presentation from a monitoring device; obtain an environmental characteristic associated with the monitored signature from the monitoring device; and adjust a signature matching result using an adjustment value when the monitored signature is determined to match a reference signature representative of reference media, the adjustment value selected from a plurality of adjustment values based on the matched reference signature and the environmental characteristic, wherein the monitored signature includes a video signature, and the environmental characteristic includes at least one of a brightness level or an ambient light level measured by the monitoring device. - View Dependent Claims (12, 13)

14. An apparatus to adjust a signature matching rate associated with monitoring a media presentation, the apparatus comprising:
-
a signature comparator to obtain a first monitored signature representative of the monitored media presentation from a monitoring device, the signature comparator to compare the first monitored signature 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 monitored signature is determined to match a first reference signature representative of reference media source from the plurality of reference media sources, the signature matching rate representative of a frequency with which reference signatures representative of a first reference media source are successfully matched during a measurement time interval, the first adjustment value selected based on the matched first reference signature and a first environmental characteristic associated with first monitored signature, the first environmental characteristic obtained from the monitoring device, wherein the first monitored signature includes a video signature, and the first environmental characteristic includes at least one of a brightness level or an ambient light level measured by the monitoring device. - View Dependent Claims (15, 16, 17, 18, 19, 20)
