Abstract

Procédé de transposition d’un flux audiovisuel L’invention concerne un procédé de transposition (100) d’un flux source de données visuelles conformées selon un premier format d’affichage en un flux transposé de données visuelles conformées selon un deuxième format d’affichage, le procédé (100) comprenant au moins les étapes suivantes effectuées : a. Identification (110) d’un premier modèle de mise en forme ; b. Détection (120) d’au moins une zone d’intérêt dans au moins une image ; c. Sélection (130) d’au moins un deuxième modèle de mise en forme ; d. Composition (140) d’au moins une image reformatée selon le deuxième format d’affichage et selon le deuxième modèle de mise en forme, à partir d’une partie au moins de la zone d’intérêt et d’une partie au moins de ladite image ; et, e. Répétition (150) des étapes a à d de sorte à former ledit flux transposé de données visuelles. Figure pour l’abrégé : Fig.2Method for transposing an audiovisual stream The invention relates to a method for transposing (100) a source stream of visual data shaped according to a first display format into a transposed stream of visual data shaped according to a second display format. , the method (100) comprising at least the following steps performed: a. Identifying (110) a first formatting model; b. Detection (120) of at least one area of interest in at least one image; vs. Selecting (130) at least one second formatting model; d. Composition (140) of at least one reformatted image according to the second display format and according to the second formatting model, from at least part of the area of interest and from at least part of said image; summer. Repeating (150) steps a through d so as to form said transposed stream of visual data. Figure for abstract: Fig.2
