Definitions

  • the extended portions 601a and 601b are padded with offscreen data, and a picture 610 including the extended portions 601a and 601b is upsampled to have the same size as that of the enhanced layer picture 600. Accordingly, data of an area 611 in the enlarged base layer picture, which corresponds to an actual image portion of the enhanced layer picture 600, can be used for prediction of the actual image portion of the enhanced layer picture 600.
  • the information of PIGS. 5a and 5b can be used as information for selection of a portion of a base layer picture, which is to be used for prediction of an enhanced layer picture, or can be used as position information of an area overlapping with an enhanced layer picture, which is to be associated with a base layer picture for use in prediction of the enhanced layer picture.

Abstract

Dans ce procédé pour décoder un signal vidéo, au moins une partie d'une image actuelle dans une couche actuelle est prédite sur la base d'au moins une partie d'une image de référence et d'informations de décalage. Les informations de décalage peuvent indiquer un décalage de position entre au moins un pixel de frontière de l'image de référence et au moins un pixel de frontière de l'image actuelle.
