Abstract

Se proporcionan un método y un aparato para codificación y decodificación. El método comprende determinar si, como una condición para no aplicar división binaria a un bloque actual, determinar si el bloque actual es un bloque límite y si una profundidad de árbol de tipo múltiple resultante de división de árbol de tipo múltiple de una hoja de árbol cuádruple, es igual o mayor que una suma de una profundidad de partición de tipo múltiple límite máxima y un desplazamiento de profundidad. Se aplica división binaria de acuerdo con un resultado de la determinación de si se satisface esta condición.
