Abstract

RESUMEN Un método para decodificar datos de video comprende recibir un flujo de bits de datos de video codificados, donde los datos de video codificados representan bloques de luminancia particionados y bloques de crominancia particionados, donde los bloques de crominancia se particionan de forma independiente de los bloques de luminancia, determinar un modo de codificación respectivo que corresponde a los respectivos bloques de luminancia particionados, decodificar los respectivos bloques de luminancia particionados de acuerdo con los respectivos modos de codificación determinados, decodificar un primer elemento de sintaxis que indica que los respectivos modos de codificación asociados con los respectivos bloques de luminancia particionados se van a utilizar para decodificar un primer bloque de crominancia particionado, donde el primer bloque de crominancia particionado está alineado con dos o más bloques de luminancia particionados, determinar un modo de codificación de crominancia para el primer bloque de crominancia particionado de acuerdo con una función de los modos de codificación respectivos de los dos o más bloques de luminancia particionados, y decodificar el primer bloque de crominancia particionado de acuerdo con el modo de codificación de crominancia determinado.
