Abstract

Un dispositivo para decodificar datos de video incluye una memoria configurada para almacenar datos de video y uno o más procesadores implementados en circuitería y configurados para almacenar conjuntos de parámetros de filtro de bucle adaptativo (ALF) en un arreglo unidimensional en la memoria, el arreglo unidimensional que tiene un tamaño predefinido de N elementos de memoria, N que es un valor de número entero positivo, en donde el uno o más procesadores se configuran para almacenar, en uno o más de los elementos de memoria del arreglo, tanto parámetros de ALF correspondientes como un valor de identificador (ID) de capa temporal que indica una capa temporal a partir de la cual se van a estimar los parámetros de ALF correspondientes; decodificar uno o más bloques de los datos de video; y filtrar el uno o más bloques utilizando los parámetros de ALF del arreglo unidimensional. El dispositivo puede codificar además el uno o más bloques antes de decodificar el uno o más bloques.
