Abstract

La presente invenzione si riferisce ad un ricevitore di trasmissioni teletext, sotto forma di una pluralità di pagine numerate, inserite nel segnale televisivo, 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 di prelevare dal contenuto di una pagina numeri di una o più altre pagine e memorizzarli, per facilitarne la selezione e/o la memorizzazione.
