    摘要： A method for matching a query against a broadcast stream includes receiving one or more broadcast streams, from which it generates and stores an audio fingerprint of a selected portion of each received broadcast stream. A query is received from which the method generates an audio fingerprint. From that point, the method continues by identifying audio content from the query, using the query audio fingerprint and a database of indexed audio content. The method concludes by identifying the source of the query using the query audio fingerprint and the stored audio fingerprints. Embodiments of the method further include predictively caching audio fingerprint sequences and corresponding audio item identifiers from a server after storing audio fingerprints extracted from the broadcast stream; and using the predictively cached audio fingerprint sequences to identify an audio item within the audio signal based on at least some additional audio fingerprints of the audio signal.

    摘要： 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.
