Patent

CA 2636571

The present invention relates to a method for conducting interlayer texture prediction in encoding or decoding of video signal . The present method constructs a pair of frame macro blocks from a single field macro block or vertically-adjacent two field macro blocks of a base layer, and using texture information of the constructed pair of frame macro blocks in interlayer texture prediction of a pair of frame macro blocks of a current layer.

La présente invention concerne une méthode de prédiction inter-couche lors du codage ou du décodage d'un signal vidéo. La méthode de l'invention consiste à construire une paire de macroblocs de trames à partir d'un seul macrobloc de champ ou de deux macroblocs de champs verticalement adjacents d'une couche de base, et à utiliser des informations de texture de la paire construite de macroblocs de trames dans la prédiction de texture inter-couche d'une paire de macroblocs de trames d'une couche courante.
