Abstract

La presente invenzione si riferisce ad un ricevitore di trasmissioni teletext, sotto forma di una pluralità di pagine, inserite nel segnale televisivo, che possono essere di tipo statico, ossia singole pagine, o di tipo fascicolo, ossia ognuna formata da una pluralità di sottopagine, che vengono sostituite a tempo nel cielo di trasmissione, comprendente mezzi per ricevere e demodulare il segnale televisivo, nonché mezzi decodificatori per ricavare anche l'associato segnale teletext e mezzi di selezione per selezionare una pagina prescelta fra quelle trasmesse, e mezzi di memoria per memorizzare almeno una pagina teletext prescelta; la caratteristica principale dell'invenzione consiste nel fatto che il ricevitore comprende mezzi addizionali che permettono la selezione diretta di una qualunque sottopagina della pagina fascicolo prescelta.
