Claim One:
1. A media monitoring method comprising: executing a media signature matching procedure, by executing an instruction with a processor, using a first analysis time window on monitored media signatures representative of monitored media to identify the monitored media, the media signature matching procedure to compare groups of neighboring monitored media signatures with respective groups of neighboring reference signatures representative of respective different reference media sources to determine first matching results, the first analysis time window defining a first size of the groups of neighboring monitored media signatures and of the groups of neighboring reference signatures to be compared by the media signature matching procedure, wherein a first one of the first matching results is determined by comparing a first group of neighboring monitored signatures spanning a duration corresponding to the first analysis time window to respective ones of the groups of neighboring reference signatures representative of the respective different reference media sources to determine respective signature comparison values corresponding to the different reference media sources; determining, by executing an instructions with the processor, the first matching results are indicative of a matching uncertainty condition when the first one of the first matching results indicates multiple reference media sources have respective signature comparison values that satisfy a comparison threshold; and in response to determining the first matching results obtained from executing the media signature matching procedure using the first analysis time window are indicative of the matching uncertainty condition, outputting second matching results obtained from executing, with the processor, the media signature matching procedure on the monitored media signatures using a second analysis time window defining a second size of the groups of neighboring monitored media signatures and of the groups of neighboring reference signatures to be compared by the media signature matching procedure, the second analysis time window being larger than the first analysis time window to reduce matching uncertainty associated with performing the media signature matching procedure on the monitored media signatures.
