Abstract

Métodos de procesamiento de video comprenden recibir datos de entrada de un bloque actual, verificar si el bloque actual es un bloque de raíz considerando uno o más criterios predefinidos, aplicar una restricción de modo, una restricción de división de croma o las restricciones de división de modo y croma al bloque actual si el bloque actual está configurado para ser un bloque de raíz, y codifica o decodifica el bloque actual. La restricción de modo restringe todos los bloques divididos del bloque actual para que sean procesados por un mismo modo de predicción y las restricciones de división de croma prohíben que los componentes de croma del bloque actual se particionen más, mientras que permite que un componente de luma del bloque actual se particione en bloques más pequeños.
