Abstract

EL TELETEXTO (TXT) CONTIENE INFORMACIONES SOBRE DEPORTE, POLITICA, TIEMPO, NOTICIAS, PELICULAS O SIMILARES. ESTOS DATOS SE TRANSMITEN EN SERIE POR MEDIO DE LAS DISPOSICIONES DE EMISION, ES DECIR PAGINA A PAGINA. A TRAVES DE LA MULTIPLICIDAD DE LAS PAGINAS SUCEDE QUE EL UTILIZADOR DEBE ESPERAR LARGO TIEMPO A LA PAGINA ELEGIDA. PARA REDUCIR ESTE TIEMPO, ES CONOCIDO LA PREVISION DE UNA MEMORIA, EN DONDE SE ALMACENAN LOS DATOS DE TELETEXTO TRANSMITIDOS, DE TAL FORMA QUE ES POSIBLE UN ACCESO MAS RAPIDO. EL OBJETIVO DE LA INVENCION ES, EN UN SISTEMA DE ESTE TIPO, LA REDUCCION DE LA OCUPACION DE MEMORIA PARA LOS DATOS DE TELETEXTO. DE ACUERDO CON LA INVENCION SE REDUCE LA MEMORIA, DE TAL MODO QUE LAS SEÑALES SON ALMACENADAS EN FORMA PROPORCIONAL Y/O LAS SEÑALES DUPLICADAS NO SE ALMACENAN MULTIPLES VECES, SINO QUE SE AGREGAN A LAS SEÑALES ALMACENADAS CON LA INFORMACION CORRESPONDIENTE A TRAVES DE UNA CANTIDAD INDICADA. SE UTILIZA EN PARTICULAR PARA UN RECEPTOR DE TELEVISION CON MEMORIA ADICIONAL PARA OPERACION DE TELETEXTO.
