Synchronization of multimedia streams

摘要

This method for synchronizing a first multimedia stream rendered on a first terminal and a second multimedia stream rendered on a second terminal (6), comprises a step of generation, from an original audio sequence of the first stream, of original audio fingerprints, and further comprises steps of :
a) generation (56) from a first sequence (52) of the first stream first audio fingerprints;
b) comparison (58) between the first fingerprints and the original fingerprints in order to obtain one or more coarse synchronization positions (P1) ;
c) correlation (60) of the first sequence (52) with one or more pieces of the original sequence located around the coarse synchronization positions (P1) in order to obtain an accurate synchronization position (P2) ;
d) rendering of the second stream on the second terminal using the accurate synchronization position (P2).
