Abstract
Un método para codificar implementado por un dispositivo de decodificación o un dispositivo de codificación, que comprende obtener información de indicación para una posición de luma (cbWidth/2, cbHeight/2) de un bloque de codificación actual, con respecto a una posición de muestra de luma superior izquierda (xCb, yCb) del bloque de codificación actual, en donde cbWidth representa un ancho del bloque de codificación actual en las muestras de luma, cbHeight representa una altura del bloque de codificación actual en las muestras de luma; establecer un valor de un modo de intra-predicción de luma asociado con el bloque de codificación actual en un primer valor por defecto, cuando la información de indicación indica que se aplica una Intra-Predicción basada en Matriz, MIP, para las muestras de luma en la posición de luma (cbWidth/2, cbHeight/2), con respecto a la posición de muestra de luma superior izquierda (xCb, yCb) del bloque de codificación actual; y obtener un valor de un modo de intra-predicción de croma basado en el valor del modo de intra-predicción de luma del bloque de codificación actual.
