Abstract

La presente invenzione si riferisce ad un ricevitore di trasmissioni teletext, comprendente mezzi per ricevere e demodulare un segnale televisivo, nonché mezzi decodificatori per ricavare anche l'associato segnale teletext e mezzi visualizzatori per visualizzare, alternativamente o contemporaneamente l'immagine televisiva e una pagina teletext prescelta; la caratteristica principale dell'invenzione consiste nel fatto che il ricevitore comprende mezzi addizionali che permettono la visualizzazione contemporanea dell'immagine televisiva e della pagina teletext senza sovraimpressione (mixing) delle due.
