Abstract

En un método y dispositivo de procesamiento de señales de video de acuerdo con la presente invención, un primer valor de predicción de un bloque de crominancia se deriva por medio de una muestra de un bloque de luminancia, se calcula un parámetro de compensación sobre la base de una región de referencia predeterminada, un segundo valor de predicción del bloque de crominancia se deriva aplicando el parámetro de compensación al primer valor de predicción, y el bloque de crominancia se puede restaurar sobre la base del segundo valor de predicción del bloque de crominancia.
