Abstract

EL DECODIFICADOR CONSTA DE UN MICROPROCESADOR (11) ENLAZADO A UN RECEPTOR DE VALORES DATOS DE TELETEXTO (10) Y A UN GENERADOR DE TEXTO (14) PARA LA PANTALLA DEL TELEVISOR. ADEMAS, UNA TARJETA DE ABONADO (12) LLAMADA CPTV ESTA ASOCIADA AL MICROPROCESADOR (11), EFECTUANDO DICHA TARJETA LA GESTION DEL CREDITO NECESARIO PARA LA COMPRA DE EMISIONES, LA MEMORIZACION DE LAS EMISIONES COMPRADAS Y PERMITIENDO LA DETERMINACION DE LAS EMISIONES COMPRADAS POR ENVIO AL MICROPROCESADOR DEL PUNTO DE ENTRADA EN LA SECUENCIA QUE LO CALCULA POR MEDIO DE INFORMACIONES QUE HA MEMORIZADO ASI COMO LAS QUE RECIBE DEL DECODIFICADOR. LOS PROGRAMAS DE EMISIONES PREVISTAS SON ENVIADOS POR LA ESTACION TERMINAL Y MEMORIZADAS EN EL MICROPROCESADOR (11). OTRA MEMORIA DEL MISMO MEMORIZA INSTRUCCIONES DE MANIPULACION A EFECTUAR PARA SELECCIONAR UNA EMISION Y COMPRARLA ASI COMO PARA RECARGAR UN CREDITO SOBRE LA TARJETA CPTV. UN TECLADO (13) PERMITE SELECCIONAR Y VISUALIZAR EN LA PANTALLA DEL TELEVISOR LAS EMISIONES PREVISTAS ASI COMO LAS INSTRUCCIONES DE MANIPULACION, LO QUE FACILITA ENORMEMENTE EL DIALOGO ENTRE EL UTILIZADOR Y EL DECODIFICADOR, CONTRIBUYENDO A EVITAR ERRORES DE MANIPULACION. EL DECODIFICADOR, SEGUN EL INVENTO, FUNCIONA COMO GUIA DEL UTILIZADOR PARA TODAS LAS OPERACIONES A REALIZAR.
