Abstract
Un aparato para generar una señal de ocultamiento de error comprende: un generador de representaciones de LPC (100) para generar una representación de LPC sustituta; un calculador de ganancias (600) para calcular una información de ganancia a partir de las representaciones de LPC; un compensador (406, 408) para compensar un efecto de ganancia de la representación de LPC sustituta empleando la información de ganancia y un sintetizador de LPC (106, 108) para filtrar información de libro de códigos empleando la representación de LPC sustituta para obtener la señal de ocultamiento de error, donde el compensador (406, 408, 900) está configurado para ponderar la información de libro de códigos o una señal de salida de síntesis de LPC.An apparatus for generating an error concealment signal comprises: an LPC representation generator (100) for generating a substitute LPC representation; a profit calculator (600) to calculate a gain information from the LPC representations; a compensator (406, 408) to compensate for a gain effect of the substitute LPC representation using the gain information and an LPC synthesizer (106, 108) to filter codebook information using the substitute LPC representation to obtain the error concealment signal, where the compensator (406, 408, 900) is configured to weight the codebook information or an LPC synthesis output signal.
