Abstract

L'invention concerne un procédé d'insertion de données (14, 16) d'une première séquence vidéo (6) dans des données (18, 20) d'une seconde séquence vidéo (10), une portion (34) de l'image (14, 16) de la première séquence vidéo (6) étant destinée à recouvrir une portion (34) de l'image (18, 20) de la seconde séquence vidéo (10). Le procédé comprend une étape de génération d'un flux codé (23) selon une norme de codage vidéo scalable de type SVC, le flux généré (23) comprenant une couche de base (26) transportant des données compressées (25) de seconde séquence vidéo (10), une couche d'amélioration (28) transportant des données compressées (27) de la première séquence vidéo (6), et des informations de reconstruction (30) d'une séquence vidéo à partir des données compressées de la couche de base (26) et de la couche d'amélioration (28). L'invention concerne également un procédé de suppression, un support d'enregistrement et un codeur.
