Abstract

La presente descripción proporciona un dispositivo de codificación y decodificación, así como un método de codificación y decodificación. En particular, la presente descripción se refiere a un método para decodificar un flujo de bits de video implementado por un dispositivo de decodificación, en donde el flujo de bits de video incluye datos que representan una imagen codificada que comprende columnas de mosaicos, el método de decodificación que comprende: obtener un elemento de sintaxis al analizar el flujo de bits de video, en donde el elemento de sintaxis se utiliza para derivar el ancho de las columnas de mosaicos, en donde el ancho de las columnas de mosaicos es uniforme; predecir la imagen de acuerdo con el ancho de las columnas de mosaicos.
