Abstract

Selon l'invention, le codage vidéo peut comprendre la réception d'une vidéo comprenant une séquence d'images. Un changement de scène peut être détectée dans la vidéo. Avant la détection du changement de scène, la vidéo peut être codée à l'aide d'une première méthode de codage. Après la détection du changement de scène, la vidéo peut être codée à l'aide d'une seconde méthode de codage.
