Abstract

Un método de división de un bloque de codificación de video para JVET, que comprende representar una unidad de árbol de codificación de JVET como un nodo raíz en una estructura de árbol cuaternario más binario (QTBT) que puede tener una ramificación cuaternaria del nodo raíz y ramificación de árboles binarios de cada uno de los nodos hoja del cuaternario usando división binaria asimétrica para separar una unidad de codificación representada por un nodo hoja cuaternario en dos unidades de codificación hijas de tamaño desigual, representar las dos unidades de codificación hijas como nodos hoja en una ramificación de árbol binario del nodo hoja cuaternario y codificar las unidades de codificación hijas representadas por nodos hoja del árbol binario con JVET, en el que adicionalmente no se permite la división de unidades de codificación hijas separadas a partir de nodos hoja cuaternarios a través de división binaria asimétrica.
