Abstract
(EN)
A method of coding and a decoder are provided. The method of coding comprising: obtaining a allow vertical TT split flag for a current node; wherein the condition that the width of the current node is larger than a predefined threshold leads to the value of the allow vertical TT split flag is first value, the value of the allow vertical TT split flag is first value indicating that vertical TT split is not allowed to be applied to the current node; determining the partition type of the current node according to the allow vertical TT split flag; partitioning the current node according to the partition type.

L'invention concerne un procédé de codage et un décodeur. Le procédé de codage comprend les étapes consistant à : obtenir un drapeau de division TT verticale pour un nœud courant; la condition selon laquelle la largeur du nœud courant est supérieure à un seuil prédéfini conduit à la valeur du drapeau de division TT verticale d'autorisation étant une première valeur, la valeur du drapeau de division TT verticale d'autorisation étant une première valeur indiquant que la division TT verticale n'est pas autorisée à être appliquée au nœud actuel; déterminer le type de partition du nœud courant selon le drapeau de division TT verticale de validation; partitionner le nœud courant selon le type de partition.
