Abstract

Un dispositivo de ejemplo para codificar (codificar o decodificar) datos de video incluye una memoria para almacenar datos de video y uno o más procesadores implementados en circuitos y configurados para formar un bloque de interpredicción para un bloque de crominancia actual de los datos de video; formar un bloque de intrapredicción para el bloque de crominancia actual de los datos de video; determinar un número de bloques vecinos a un bloque de luminancia correspondiente al bloque de crominancia actual que están codificados por intrapredicción; determinar un primer peso y un segundo peso de acuerdo con el número de bloques vecinos que están codificados por intrapredicción; aplicar el primer peso al bloque de interpredicción y el segunda peso al bloque de intrapredicción; combinar el primer bloque de interpredicción ponderado y el segundo bloque de intrapredicción ponderado para formar un bloque de predicción para el bloque de crominancia actual; y codificar el bloque de crominancia actual utilizando el bloque de predicción.
