Abstract:
1. A method comprising: determining a plurality of trigger fingerprints from content being played back on a playback device, each trigger fingerprint identifying a corresponding trigger time point of a sequence of trigger time points in the content and at which trigger time point at least one corresponding action is to be triggered, the determining being performed by a processor; accessing a database that includes a plurality of reference fingerprints, previously derived from the content, and a plurality of reference actions, each reference fingerprint identifying at least one corresponding reference action to be performed at a reference time point identified by the reference fingerprint; identifying the corresponding reference action by obtaining a match in the database between a trigger fingerprint among the plurality of trigger fingerprints and a reference fingerprint among the plurality of reference fingerprints; and performing a reference action that corresponds to the reference fingerprint on the playback device.
