METHOD FOR SYNCHRONIZING A CONTENT STREAM AND A SCRIPT FOR OUTPUTTING ONE OR MORE SENSORY EFFECTS IN A MULTIMEDIA SYSTEM

摘要

A method for synchronizing a content stream (10) and a script (70) comprises the acts of calculating (80) a fingerprint (30) comprising a number of bits, from a portion (20) of the content stream; determining (50) a time value (40) corresponding to the calculated fingerprint (30); synchronizing a portion of the script (90) that corresponds to the time value (40) and the portion (20) of the content stream (10). The method is characterized in comprising a step in which the number of bits is determined in dependence of at least one of the fingerprints chosen from a group comprising the calculated fingerprint (30), an expected fingerprint (130) corresponding to said calculated fingerprint, another calculated fingerprint (110) calculated from another portion (100) of said content stream, and another expected fingerprint (120) corresponding to said another calculated fingerprint (110). The script (70) represents one or more sensory effects to be output in an effects signal to an effects controller.
