Abstract

POR PARTE DEL CIRCUITO DE EMISION PUEDEN SER TRANSMITIDOS ADICIONALMENTE A LOS DATOS BASICOS DEL TELETEXTO DE PAGINAS DE TELETEXTO ESTRUCTURADAS CONVENCIONALMENTE, DATOS COMPLEMENTARIOS PARA CADA UNA DE LAS PAGINAS DE TELETEXTO EN FORMA DE UNA O VARIAS PAGINAS COMPLEMENTARIAS CORRESPONDIENTES, CON PAGINAS NUMERADAS EN EL SISTEMA HEXADECIMAL, LAS CUALES ESTAN ESTRUCTURADAS EN EL FORMATO CONVENCIONAL DE LAS PAGINAS DEL TELETEXTO, Y POR PARTE DEL CIRCUITO DE RECEPCION SON MEMORIZADOS INTERCALADAMENTE DE FORMA SEPARADA DE LOS DATOS BASICOS DE UNA PAGINA DE TELETEXTO DESEADA. LOS NUMEROS DE LAS PAGINAS COMPLEMENTARIAS CODIFICADAS EN EL SISTEMA HEXADECIMAL FUERA DEL SISTEMA DECIMAL, ESTAN ASIGNADOS DE ACUERDO CON UN ESQUEMA FIJO DE LAS PAGINAS DEL TELETEXTO CONVENCIONALES, DEL SISTEMA DECIMAL ASIGNADO CON EL NUMERO DE PAGINAS SELECCIONABLES POR EL TECLADO DE DIEZ TECLAS. CON EL FIN DE FACILITAR UNA TRANSMISION COMPATIBLE DE PAGINAS DE TELETEXTO EN PANTALLAS DE 16:9, SON TRANSMITIDOS OTROS DATOS COMPLEMENTARIOS CON UN CONTENIDO DE IMAGEN INDEPENDIENTE, EN VEZ O ADICIONALMENTE CON LOS DATOS COMPLEMENTARIOS CON LA MISMA CODIFICACION Y FORMATO. LOS OTROS DATOS COMPLEMENTARIOS SON TRANSMITIDOS DE NUEVO EN UNA PANTALLA CON UN FORMATO DE LA ALTURA DE LA PAGINA DE 16:9 EN UNA ZONA DE LA PANTALLA, JUNTO A LA PAGINA DEL TELETEXTO CONVENCIONAL O JUNTO A UNA IMAGEN TELEVISIVA CONVENCIONAL CON EL CORRESPONDIENTE FORMATO DE LA ALTURA DE LA PAGINA.
