Abstract
Selon un exemple, la présente invention comprend les étapes consistant à recevoir une séquence vidéo codée comprenant des images codées d'une séquence vidéo et à recevoir des paramètres de synchronisation destinés à la séquence vidéo codée qui comprennent une échelle de temps et un nombre d'unités dans un tic-tac d'horloge tout au plus une fois dans une structure de syntaxe d'ensemble de paramètres vidéo (vps) référencée par la séquence vidéo codée et tout au plus une fois dans une partie d'informations d'utilisation vidéo (vui) d'une structure de syntaxe d'ensemble de paramètres de séquence (sps) référencée par la séquence vidéo codée. Un autre exemple selon l'invention comprend les étapes consistant à coder des images d'une séquence vidéo pour générer une séquence vidéo codée et à signaler les paramètres de synchronisation de la séquence vidéo codée en signalant au moins en partie une échelle de temps et un nombre d'unités dans un tic-tac d'horloge tout au plus une fois dans une structure de syntaxe vps et tout au plus une fois dans une partie vui d'une structure de syntaxe sps.
