Abstract

Un decodificador decodifica un primer grupo de datos y utiliza el primer grupo de datos decodificados para reconstruir la señal de acuerdo con un primer nivel de calidad. El decodificador decodifica además un segundo grupo de datos e identifica una operaci6n de sobremuestreo especificada por el segundo grupo de datos decodificados. El decodificador aplica la operación de sobremuestreo identificada en el segundo grupo de datos decodificados a la señal reconstruida en el primer nivel de calidad para reconstruir la señal en un segundo nivel mayor de calidad. Para mejorar la señal reconstruida el decodificador busca los datos residuales del segundo grupo de datos decodificados. Los datos residuales indican cómo modificar la señal reconstruida en el segundo nivel de calidad después de la aplicación de la operación de sobremuestreo como se describe ante. El decodificador entonces modifica la señal reconstruida en el segundo nivel de calidad como se especifica mediante los datos residuales.
