Abstract

Un método para descodificar una señal de video de multicapa, de acuerdo con la presente invención, determina si una imagen correspondiente en una capa inferior se utiliza como imagen de referencia de capa intermedia para una imagen actual en una capa superior, en función de un identificador de nivel de tiempo de la capa inferior, realiza predicción de capa intermedia para la imagen actual al utilizar la imagen correspondiente si la imagen correspondiente en la capa inferior se utiliza como la imagen de referencia de capa intermedia para la imagen actual en la capa superior, restablece la imagen actual al utilizar una muestra de predicción adquirida a través de la predicción de capa intermedia y una capa residual de la imagen actual, y aplica de manera selectiva un filtro de bucle a un límite de mosaico de la imagen actual restablecida en función de un indicador de filtro de capa para la capa superior.
