Abstract

RESUMEN Un dispositivo para decodificar datos de video incluye una memoria configurada para almacenar datos de video y uno o más procesadores implementados en circuitos y configurados para almacenar conjuntos de parámetros de filtro de bucle adaptativo (ALF) en una matriz unidimensional en la memoria, en donde la matriz unidimensional tiene un tamaño predefinido de elementos de memoria N, donde N tiene un valor entero positivo, donde el procesador o los procesadores están configurados para almacenar, en uno o más de los elementos de memoria de la matriz, los parámetros de ALF correspondientes y un valor identificador de capa temporal (ID) que indica una capa temporal a partir de la cual se estimarán los parámetros de ALF correspondientes; decodificar uno o más bloques de datos de video; y filtrar el bloque o los bloques mediante la utilización de los parámetros de ALF de la matriz unidimensional. El dispositivo puede codificar además el bloque o los bloques antes de decodificar el bloque o los bloques.
