Title (EN) VARIABLE LENGTH CODES FOR SCALABLE VIDEO CODING
(FR) CODES A LONGUEUR VARIABLE POUR CODAGE VIDEO ADAPTABLE
Abstract:
(EN) A method for coding spatial and quality enhancement information in scalable video coding using variable length codes. Conventional systems have been capable of using variable length codes only with nonscalable video coding. In the present invention, the coded block pattern for each block of information, significance passes, and refinement passes can all be coded with different types of variable length codes.
(FR) Procédé de codage d'information d'amélioration spatiale et qualitative en codage vidéo adaptable, au moyen de codes à longueur variable. Les systèmes classiques pouvaient utiliser des codes à longueur variable seulement en codage vidéo non adaptable. Désormais, le motif de bloc codé pour chaque bloc d'information, les passages significatifs et les passages d'affinement peuvent tous être codés avec différents types de codes à longueur variable.
