Patent ID: 7043684

Claim:
A method of synchronizing two digital data streams with the same content, the method comprising the steps of: a) generating at given intervals for each of the two digital data streams S 1 and S 2 at least two characteristic numbers expressing at least one characteristic parameter of their content; b) generating from said numbers points D 1 and D 2 for each of the two streams S 1 and S 2 representing at least one of said characteristic parameters in a space of at least two dimensions, the points D 1 corresponding to the stream S 1 and the points D 2 corresponding to the stream S 2 being situated in a time period T and defining trajectories representative of the data streams S 1 and S 2 to be synchronized; c) shifting the time periods of duration T assigned to the digital data streams S 1 and S 2 relative to each other by calculating a criterion of superposition of said trajectories having an optimum value representing the required synchronization; d) choosing the shift between the time periods corresponding to said optimum value as a value representative of the synchronization.
