Patent ID: 8903524

Claim:
A process for scanning and/or synchronizing audio/video events, the process comprising the following operating steps: acquiring at least one signal with at least one audio processor, the at least one signal associated with audio content of an audio/video event; dividing the acquired at least one signal into a plurality of segments corresponding to different moments of the signal; generating a spectrogram comprising a plurality of frequency bands in each segment of the plurality of segments of the divided signal; locating within the generated spectrogram, among the bands of each segment of the signal, one or more peaks in which a magnitude of the corresponding band is greater than each of a plurality of magnitudes of the other bands; locating among said located peaks of the generated spectrogram one or more transition peaks, each of which at a given moment have a band differing from the bands of the peaks at a previous moment; combining, in at least one or more transitions, the moment and the band of a transition peak, with the moment and the band of one or more subsequent transition peaks; and associating one or more hashes corresponding to one or more transitions with at least one moment at which the transitions occur in the acquired at least one signal.
