Patent ID: 10614115

Abstract:
A computer system arranged to determine whether a candidate media-component matches one or more reference media-components, wherein the computer system comprises: at least one processing device arranged to receive the candidate media-component and the at least one processing device further comprising: a window generator arranged to select a portion of the candidate media-component; a fingerprint generator arranged to generate a fingerprint from the portion of the candidate media-component selected by the window generator, wherein the at least one processing device is arranged to cause the window generator to move through the candidate media component thereby selecting a plurality of portions of the candidate media component from at least some of which the fingerprint generator is arranged to generate a candidate fingerprint thereby creating a sequence of candidate fingerprints; a comparator arranged to compare at least some of the candidate fingerprints within the sequence of candidate fingerprints against fingerprints within the sequences of reference fingerprints accessed from a store to determine if the store contains a sequence of reference fingerprints which matches the sequence of candidate fingerprints; the comparator being arranged to assess at least one characteristic of the comparison between the fingerprints within the sequence; wherein the system is arranged to determine that the candidate media-component matches a reference media-component should the at least one processing device determine that the candidate sequence of fingerprints matches a sequence of reference finger prints.
