Abstract

Un método de decodificación incluye recibir un flujo de bits que tiene una pluralidad de capas y un conjunto de parámetros de video (VPS), donde el VPS incluye una bandera de capa de referencia directa, donde la bandera de capa de referencia directa igual a un primer valor especifica que una segunda capa no es una capa de referencia directa para una primera capa, y donde la bandera de capa de referencia directa igual a un segundo valor especifica que la segunda capa es la capa de referencia directa para la primera capa; derivar una bandera de capa de referencia al: establecer inicialmente la bandera de capa de referencia al primer valor; y actualizar la bandera de capa de referencia al segundo valor cuando la bandera de capa de referencia directa tiene el segundo valor; y decodificar una imagen de la primera capa de acuerdo con la bandera de capa de referencia para obtener una imagen decodificada.
