Abstract
LA EFICIENCIA DE PROCESAMIENTO DE UN PROCESO UTILIZADO PARA DECODIFICAR CUADROS DE UN FLUJO DE BITS AC-3 MEJORADO, SE MEJORA PROCESANDO CADA BLOQUE DE AUDIO EN UN CUADRO SÓLO UNA VEZ. LOS BLOQUES DE AUDIO DE DATOS CODIFICADOS SE DECODIFICAN POR ORDEN DE BLOQUE; EN UN LUGAR DE POR ORDEN DE CANAL. SE REVELAN LOS PROCESOS DE DECODIFICACIÓN EJEMPLARES PARA LAS CARACTERÍSTICAS DE CODIFICACIÓN DE FLUJO DE BITS MEJORADO COMO EL PROCESAMIENTO DE TRANSFORMADA HÍBRIDA ADAPTATIVA Y LA EXTENSIÓN ESPECTRAL.
