Patent ID: 8020000

Claim:
A method comprising: providing a trigger time point (T n ; T n+1 ) of a plurality of trigger time points within a multimedia signal, the trigger time point (T n ; T n+1 ) corresponding to a segment of a plurality of segments of the multimedia signal, the trigger time point (T n ; T n+1 ) corresponding to at least one of a predetermined distance from the start of the segment or a predetermined distance from the end of the segment, each segment of the plurality of segments being identified by one of the plurality of trigger time points and corresponding to specific content to be shown to a user; providing a representation of an action that corresponds to the specific content to be shown in the segment of the multimedia signal, the trigger time point (T n ; T n+1 ) indicating a time point within the multimedia signal at which the action is to be triggered during a playback of the multimedia signal; deriving a fingerprint based on the segment of the multimedia signal; and associating the derived fingerprint with the action.
