Abstract

EN LOS CONOCIDOS PROCESOS ADAPTIVOS DE TRANSMISION DE TELETEXTO, LAS LINEAS DE DATOS EN LOS BLOQUES DE DATOS QUE CORRESPONDEN A LINEAS DE TELETEXTO NO USADAS, SON "RELLENADAS" POR ENCABEZAMIENTOS O SUS REPETICIONES, PROLONGANDO DE ESE MODO EL CICLO DE DATOS SIN TRANSMITIR NINGUNA INFORMACION UTIL. SI EN LUGAR DE LAS TRANSMISIONES REDUNDANTES SE TRANSMITEN OTROS DATOS, ENTONCES SE PUEDEN PRESENTAR PROBLEMAS CON LOS DECODIFICADORES CONVENCIONALES DURANTE EL BORRADO DEL ALMACENADO AUXILIAR DE LA PAGINA. DE ACUERDO CON LA INVENCION, BLOQUES DE DATOS ESPECIALES O PARTES DE ELLOS SON TRANSMITIDOS EN LOS PUNTOS REDUNDANTES PREVIAMENTE, O UN ENCABEZAMIENTO ES TRANSMITIDO ANTES DEL CORRESPONDIENTE BLOQUE DE DATOS, CON UN INTERVALO DE TIEMPO SUFICIENTE (APROXIMADAMENTE 20 MILISEGUNDOS), MIENTRAS QUE OTRO BLOQUE DE DATOS ES INSERTADO ANTES DEL BLOQUE DE DATOS INTERESADO. POR AJUSTE DE LOS ERRORES DE BIT APROPIADOS O UN BIT MODO PARALELO, ES EVITADA LA INTERRUPCION PREMATURA DE LA ADQUISICION DE DATOSPOR EL DECODIFICADOR.
