Abstract
La invención se refiere a un método para procesar una señal digital, implementada durante la decodificación de la señal, con el fin de remplazar una sucesión de muestras perdidas durante la decodificación, el método que comprende los pasos de generar una estructura de una señal para remplazar la sucesión perdida, esta estructura que comprende componentes espectrales determinados a partir de muestras válidas recibidas durante la decodificación antes de la sucesión de las muestras perdidas; generar un residuo entre una señal digital disponible en el decodificador, que comprende muestras válidas recibidas y una señal generada a partir de dichos componentes espectrales; y extraer los bloques a partir de dicho residuo, método en el cual los bloques de las ventanas ponderadas se inyectan en la estructura usando un método de adición de traslape, los bloques inyectados se traslapan al menos parcialmente en el tiempo.
