Title (EN) APPARATUS OF PREDICTIVE CODING/DECODING USING VIEW-TEMPORAL REFERENCE PICTURE BUFFERS AND METHOD USING THE SAME
(FR) DISPOSITIF DE CODAGE/DECODAGE PREDICTIF PAR LE BIAIS DE TAMPONS D'IMAGES DE REFERENCE A DIMENSION SPATIO-TEMPORELLE ET PROCEDE D'UTILISATION
Abstract:
(EN) Provided are an apparatus and method for predictive coding/decoding for improving a compression rate of multiview video using one or two additional reference frame buffers. The predictive encoding apparatus includes: a multiview reference picture providing unit for providing a reference picture for a predictive encoding according to temporal and spatial GOP structure information; a prediction unit for creating a vector by predicting which part of the reference picture inputted from the multiview reference picture providing unit is referred by a picture to currently encode; a transforming and quantizing unit for obtaining a difference signal between the predicted signal inputted from the prediction unit and a picture signal to currently encode, transforming the obtained difference signal, quantizing the transformed signal, and compressing the quantized signal; and an entropy encoding unit for encoding the quantized signal and the vectors according to a predetermined scheme and outputting the encoded signal.
(FR) Dispositif et procédé pour le codage/décodage prédictif permettant d'améliorer un taux de compression en vidéo multivue, par le biais d'un ou plusieurs tampons d'images de référence complémentaires. Le dispositif comprend : unité fournissant des images de référence multivue qui fournit une image de référence pour un codage prédictif selon une information de structure spatio-temporelle de groupe d'images ; unité de prédiction pour la création de vecteur par prédiction de la partie de l'image de référence issue de l'unité précédente qui est prise en référence par une image à coder ; unité de transformation et de quantification permettant de déterminer un signal de différence entre le signal prédit issu de l'unité de prédiction et un signal d'image à coder, de transformer le signal de différence obtenu, de quantifier le signal transformé et de comprimer le signal quantifié ; unité de codage par entropie pour le codage du signal quantifié et des vecteurs selon un schéma préétabli et pour la fourniture du signal codé.
