Abstract
La présente invention concerne un procédé et un dispositif de synchronisation de flux de données médiatiques (AU, VI) comportant respectivement des contenus de données médiatiques (A1, A2, V1, V2) d'une classe médiatique prédéfinie. Une synchronisation temporelle des flux de données (AU, VI) est effectuée en fonction des contenus de données médiatiques (A1, A2, V1, V2).
