1. A method for determining the temporal relationship between a first video sequence and a second video sequence, said method comprising:
- obtaining from said first video sequence a first parameter such that the evolvement of said first parameter over time corresponds to the change of the entropy of said first video sequence over time;
obtaining from said second video sequence a second parameter such that the evolvement of said second parameter over time corresponds to the change of the entropy of said second video over time,matching the evolvement of said first parameter over time to the evolvement of said second parameter over time, whereinsaid matching of said evolvement of said first and said second parameter over time is performed by calculating a correlation function between the evolvement of said first parameter over time with the evolvement of said second parameter over time to thereby determine the temporal relationship between the two video sequences.

8. An apparatus for determining the temporal relationship between a first video sequence and a second video sequence, said apparatus comprising:
-
a module for obtaining from said first video sequence a first parameter such that the evolvement of said first parameter over time corresponds to the change of the entropy of said first video sequence over time; a module for obtaining from said second video sequence a second parameter such that the evolvement of said second parameter over time corresponds to the change of the entropy of said second video over time; a module for matching the evolvement of said first parameter over time to the evolvement of said second parameter over time, wherein said matching of said evolvement of said first and said second parameter over time is performed by calculating a correlation function between the evolvement of said first parameter over time with the evolvement of said second parameter over time to thereby determine the temporal relationship between the two video sequences. - View Dependent Claims (9, 10, 11, 12, 13)
