Method for the synchronization of two digital data flows with identical content

摘要

The invention relates to 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 S₁ and S₂ at least two characteristic numbers expressing at least one parameter characteristic of their content; b) generating from said numbers points D₁ and D₂ for each of the two streams S₁ and S₂ representing at least one of said characteristic parameters in a space of at least two dimensions, the points D₁ corresponding to the stream S₁ and the points D 2 corresponding to the stream S 2 that are situated in a time period T defining trajectories representative of the data streams S₁ and S₂ to be synchronized; c) shifting the time periods of duration T assigned to the digital data streams S₁ and S₂ 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.
