Abstract

Selon l'invention, on génère des signaux acoustiques (snd) à partir d'un flux de données vidéo qui contient une séquence chronologique d'images individuelles (img). On commence par déterminer un champ vecteur de déplacement (vfd) à partir des données image des images individuelles (img), par exemple, à l'aide d'un algorithme MPEG puis on dérive au moins une grandeur caractéristique (chs) du champ vecteur de déplacement (vfd), par exemple, un vecteur de déplacement prédominant dans un module d'analyse (AAN). Et à l'appui de ces grandeurs (chs), on génère un signal acoustique (snd) à l'aide d'un module de synthèse (SYN).
