A computer-implemented system and method are described for encoding video For example, a method according to one embodiment comprises selecting a tile size for subdividing each image in a sequence of images based on a specified type of encoding algorithm to be used for encoding the tiles, wherein M tiles are encoded for each image, each tile being encoded according to a first encoding format or a second encoding format, each tile having a designated tile location within each image, specifying a rotating pattern to be used for encoding the tiles over a sequence of N images, the rotating pattern comprising encoding only certain tiles of each image using the first encoding format, and rotating the tile locations selected for the first encoding format over the N images to ensure that all M tiles have been encoded according to the first encoding format across the N images

Linvention concerne un système informatisé et un procédé de codage vidéo. Par exemple, un procédé selon un mode de réalisation consiste à: choisir une taille des pavés permettant de subdiviser chaque image en une suite d'images sur la base d'un type spécifié d'algorithme de codage à utiliser pour coder les pavés, M pavés étant codés pour chaque image, chaque pavé étant codé selon un premier format de codage ou un second format de codage, chaque pavé occupant un emplacement désigné dans chaque image; spécifier une configuration de rotation à utiliser pour coder les pavés dans une suite de N images, la configuration de rotation consistant à coder uniquement certains pavés de chaque image selon le premier format de codage; et mettre en rotation les emplacements des pavés choisis pour le premier format de codage dans les N images afin d'assurer que tous les M pavés ont été codés selon le premier format de codage dans l'ensemble des N images.
