Abstract

Se proporcionan un procedimiento de descodificación de imágenes, un descodificador y un medio de almacenamiento informático. El procedimiento incluye lo siguiente. Se adquiere una tasa de bits correspondiente a una imagen actual. El flujo de bits se analiza para obtener un indicador correspondiente a la imagen actual. Una función de descodificación cruzada se deshabilita cuando una forma de descodificación indicada por el indicador es la descodificación independiente de los componentes de color, en la que la función de descodificación cruzada permite la descodificación basada en la dependencia entre los componentes de color.
