Abstract

L'invention concerne un procédé de transformation de multiples flux vidéo en un seul flux vidéo. Selon un mode de réalisation, le procédé consiste à recevoir des flux vidéo au niveau d'un dispositif de codage, chaque flux vidéo multiple étant formé par des trames vidéo; à coder les trames vidéo pour chaque flux vidéo à de multiples débits binaires pour former de multiples qualités de résolution pour chaque flux vidéo; et à combiner les flux pour les multiples qualités de résolution des flux vidéo afin de former un flux de trames de grappes vidéo. L'invention concerne également un appareil de transformation de multiples flux vidéo en un seul flux vidéo. L'invention concerne également un support non transitoire lisible par ordinateur mémorisant des instructions de programme. Les instructions du programme, lorsqu'elles sont exécutées par un ordinateur ou un processeur, amènent l'appareil à mettre en œuvre le procédé.
