Abstract

L'invention concerne un dispositif de commande de codage multi-flux. Lors du codage de chaque donnée vidéo par au moins deux systèmes de codage différents l'un de l'autre, une unité de prédiction de codage (204) établit, pour le codage effectué par chaque système de codage dans une unité de codage (202), le paramétrage du codage suivant en fonction d'une quantité de codes et/ou d'un paramètre de codage suite au codage, de la quantité de codes et du paramètre de codage avant le codage, du débit de trames à coder et du débit de sortie d'une unité de sortie (203). Il est donc possible de réguler la quantité de codes totale par unité de temps respectivement codée par une pluralité de systèmes de codage en fonction du débit de transmission de l'unité de sortie 203. Il est donc possible d'éviter une dégradation de la qualité d'image et d'obtenir une image à haute résolution lorsque des données de codes respectivement codées par une pluralité de systèmes de codage sont fournies simultanément.
