Title (EN) SYSTEM AND METHOD FOR ACHIEVING INTER-LAYER VIDEO QUALITY SCALABILITY
(FR) SYSTEME ET PROCEDE DESTINES A ASSURER UNE VARIABILITE D'ECHELLE ENTRE COUCHES DE LA QUALITE VIDEO
Abstract: front page image
(EN)A system and method for providing quality scalability in a video stream. A bit stream is provided with a video sequence having a base layer and an enhancement layer. The enhancement layer includes a plurality of enhancement layer blocks, each of which includes a block coefficient. Each layer block coefficient is assigned to one of a plurality of zones, and layer block coefficients assigned to a particular one of the plurality of zones are removed periodically.
(FR)Système et procédé destinés à assurer une variabilité d'échelle dans un flux vidéo. On forme un flux binaire avec une séquence audio possédant une couche de base et une couche d'accentuation. La couche d'accentuation comprend une pluralité de couches d'accentuation dont chacune comprend un coefficient de bloc. Chaque coefficient de bloc de couche est attribué à l'une des zones, et les coefficients de bloc de couche attribués à une zone prédéterminée sont retirés périodiquement.
