Abstract

Se describe un método de decodificación de datos de vídeo que comprende la recepción de una corriente de bits que comprende información de imágenes codificadas; la decodificación de una imagen con base en la información de imagen codificada y la obtención de datos de luminancia asignados a los canales de luminancia que comprenden una pluralidad de canales y datos de croma asignados a un canal de croma que comprende un canal a partir de los datos generados por la decodificación de la imagen; la fusión de los datos de luminancia obtenidos como datos de luminancia que tienen un componente; la división de los datos de luminancia que tienen un componente; la división de los datos de croma obtenidos en datos de croma que tienen una pluralidad de componentes; y la reconstrucción de la imagen con base en los datos de luminancia que tienen un componente generado por la fusión de los datos de luminancia obtenidos en los datos de croma divididos que tienen la pluralidad de componentes.
