Abstract

La presente invenzione si riferisce ad un circuito ricevitore di segnali teletext, con funzioni di acquisizione dati e di visualizzazione; la caratteristica principale dell'invenzione consiste nel fatto che il circuito prevede una separazione tra la funzione di acquisizione e la funzione di visualizzazione, in modo da consentire l'acquisizione e la memorizzazione dei dati in tempo reale.
