Abstract

REFERIDO A UN METODO Y UN APARATO PARA DECODIFICAR UN CUADRO DE UNA SENAL DE AUDIO DIGITAL CODIFICADA Y MEDIO DE ALMACENAMIENTO QUE GRABA UN PROGRAMA DE INSTRUCCIONES. L AEFICIENCIA DE PROCESAMIENTO DE UN PROCESO UTILIZADO PARA DECODIFICAR CUADROS DE FLUJO DE BITS AC-3 MEJORADO SE MEJORA PROCESANDO CADA BLOQUE DE AUDIO EN UN CUADRO UNA SOLA VEZ. LOS BLOQUES DE AUDIO DE DATOS CODIFICADOS SE DECODIFICAN POR ORDEN DE BLOQUE EN LUGAR DE POR ORDEN DE CANAL. SE REVELAN LOS PROCESOS DE DECODIFICACION EJEMPLARES PARA LAS CARACTERISTICAS DE CODIFICACION DE FLUJO DE BITS MEJORADO COMO EL PROCEDIMIENTO DE TRANSFORMADA HIBRIDA ADAPTATIVA Y LA EXTENSION ESPECTRAL
