REDUCING SIGNATURE MATCHING UNCERTAINTY IN MEDIA MONITORING SYSTEMS

摘要

Methods, apparatus, systems and articles of manufacture (e.g., physical storage media) to reduce signature matching uncertainty in media monitoring systems are disclosed. Example media monitoring methods disclosed herein include executing a media signature matching procedure using a first analysis window on monitored media signatures representative of monitored media to identify the monitored media. Example media monitoring methods disclosed herein also include, in response to determining first matching results obtained from executing the media signature matching procedure using the first analysis window are indicative of a matching uncertainty condition, outputting second matching results obtained from executing the media signature matching procedure on the monitored media signatures using a second analysis window that is larger than the first analysis window.

1. A media monitoring method comprising:
executing a media signature matching procedure, with a processor, using a first analysis window on monitored media signatures representative of monitored media to identify the monitored media; and in response to determining first matching results obtained from executing the media signature matching procedure using the first analysis window are indicative of a matching uncertainty condition, outputting second matching results obtained from executing the media signature matching procedure on the monitored media signatures using a second analysis window that is larger than the first analysis window.
