Abstract

EN UN DECODIFICADOR DE VOZ QUE EXPERIMENTE BORRADO DE MARCOS, SE INCREMENTA EL RETRASO DE PASO ASOCIADO CON EL PRIMERO DE LOS MARCOS CONSECUTIVOS BORRADOS. EL VALOR DEL INCREMENTO SE UTILIZA COMO RETRASO DE PASO PARA EL SEGUNDO DE LOS MARCOS CONSECUTIVOS BORRADOS. EL RETRASO DE PASO ASOCIADO CON EL PRIMERO DE LOS MARCOS CONSECUTIVOS BORRADOS PUEDE CORRESPONDER CON LA INFORMACION DEL RETRASO DE PASO RECIBIDA DESDE UN DECODIFICADOR DE VOZ (ASOCIADO CON UN MARCO NO BORRADO), O PUEDE SER EN SI MISMO EL RESULTADO DE UN INCREMENTO AÑADIDO A UN VALOR TODAVIA PREVIO DEL RETRASO DE PASO (ASOCIADO CON UN MARCO BORRADO TODAVIA PREVIO).
