Abstract

Un aparato electrónico realiza un método de descodificación de datos de video; el método incluye: recibir, a partir de la señal de video, un cuadro de imagen que incluye un primer componente y un segundo componente; reconstruir muestras del primer componente a través de un primer filtro en bucle; reconstruir muestras del segundo componente a través de un segundo filtro en bucle; determinar un clasificador para el primer componente a partir de una o más muestras reconstruidas del segundo componente con respecto a una muestra reconstruida respectiva del primer componente; seleccionar un primer desplazamiento de muestra para la respectiva muestra reconstruida del primer componente según el clasificador; aplicar una pluralidad de filtros en paralelo con la selección del primer desplazamiento de muestra para obtener una pluralidad de desplazamientos paralelos; y recortar una salida de una combinación de la respectiva muestra reconstruida del primer componente, el primer desplazamiento de muestra y la pluralidad de desplazamientos paralelos de la pluralidad de filtros.
