Abstract
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 Sand Sat least two characteristic numbers expressing at least one parameter characteristic of their content; b) generating from said numbers points Dand Dfor each of the two streams Sand Srepresenting at least one of said characteristic parameters in a space of at least two dimensions, the points Dcorresponding to the stream Sand the points Dcorresponding to the stream Sthat are situated in a time period T defining trajectories representative of the data streams Sand Sto be synchronized; c) shifting the time periods of duration T assigned to the digital data streams Sand Srelative 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.
