Title
(EN) METHOD FOR DECODING VIDEO SIGNAL ENCODED USING INTER-LAYER PREDICTION
(FR) PROCEDE PERMETTANT DE DECODER UN SIGNAL VIDEO CODE PAR PREDICTION ENTRE LES COUCHES
Abstract
(EN)
A method for receiving and decoding an encoded bitstream of a first layer and an encoded bitstream of a second layer into a video signal is provided. It is determined whether or not a block temporally coincident with a target block in a picture of the first layer is present in the bitstream of the second layer. An operation for checking information (intra_base_flag and residual_prediction_flag) indicating whether or not the target block has been predicted based on data of a block in a different layer corresponding to the target block is skipped if no block temporally coincident with the target block is present in the bitstream of the second layer. This method eliminates the need for encoders to transmit unnecessary information (intra_base_flag and residual_prediction_flag) when performing inter-layer prediction using a temporally adjacent frame.

La présente invention concerne un procédé qui consiste à recevoir et à décoder un flux binaire codé d'une première couche et un flux binaire codé d'une seconde couche en un signal vidéo. Le mode de réalisation décrit dans cette invention consiste à déterminer si un bloc temporairement coïncident avec un bloc cible dans une image de la première couche est présent dans le flux binaire de la seconde couche. Le procédé comprend également une opération qui consiste à vérifier si les informations (à l'intérieur de la balise de base et de la balise de prédiction résiduelle) indiquent, ou non, que le bloc cible a été prédit sur la base des données d'un bloc dans une couche différente correspondant au bloc cible est éliminé si aucun bloc temporairement coïncident avec le bloc cible ne se trouve dans le flux binaire de la seconde couche. Ce procédé permet d'éviter que les codeurs ne transmettent des informations inutiles (à l'intérieur de la base de base et de la balise de prédiction résiduelle) lors de l'exécution de la prédiction entre les couches au moyen d'une trame temporairement adjacente.
