Patent ID: 8660267

Claim:
A method comprising: generating a set of fingerprints based on a multimedia signal, the set of fingerprints including a first fingerprint among the set of fingerprints, the first fingerprint being generated based on content of a segment of the multimedia signal among a plurality of segments of the multimedia signal; determining that the first fingerprint among the set of fingerprints matches a second fingerprint stored in a first database, a second database storing a representation of an action as being associated with the second fingerprint and as corresponding to a trigger time point that is at least one of a predetermined distance from the start of the segment or a predetermined distance from the end of the segment, the determining being performed by a processor of a machine based on a comparison of the first fingerprint among the set of fingerprints with the second fingerprint stored in the first database; and retrieving the representation of the action stored as being associated with the second fingerprint and as corresponding to the trigger time point.
