Title (EN) METHOD OF ENCODING AND DECODING VIDEO SIGNALS
(FR) PROCEDE DE CODAGE ET DE DECODAGE DE SIGNAUX VIDEO
Abstract:
(EN) Disclosed herein is a method of encoding video signals. The method includes creating a bit stream of a first layer by encoding the video signals, and creating a bit stream of a second layer by encoding the video signals based on the first layer. When residual data, corresponding to an image difference, within the first layer, is up-sampled and used for the encoding of the second layer, the residual data is up-sampled for each block that is predicted based on motion compensation.
(FR) L'invention porte sur un procédé de codage de signaux vidéo. Ce procédé consiste à créer un flux binaire d'une première couche codant les signaux vidéo et un flux binaire d'une seconde couche codant les signaux vidéo en fonction de la première couche. Lorsque des données résiduelles, correspondant à une différence d'image, dans la première couche, sont suréchantillonnées et utilisées pour le codage de la seconde couche, ces données résiduelles sont suréchantillonnées pour chaque bloc prévu en fonction d'une compensation du mouvement.
