Abstract:
A method and system for identification of a deviation from a periodic behavior pattern in a sequence of multimedia content segments are provided. The method includes generating at least one signature for each multimedia content segment of the sequence of multimedia content segments; comparing at least two of the generated signatures to detect a periodic behavior pattern, wherein the compared at least two signatures represent consecutive multimedia content segments; and comparing at least one signature of at least a subsequently received multimedia content segment to at least one signature representing the periodic behavior pattern to identify a deviation from the periodic behavior pattern.
