Abstract
Il circuito di controllo video è particolarmente indicato per applicazioni multimediali, in cui oltre ai consueti servizi di trasmissione telefonica vocale e di trasmissione dati, vengono offerti servizi di trasmissione di immagini. Esso è in grado di svolgere funzioni per il trattamento sia di immagini video di tipo fotografico, sia di immagini di tipo grafico, soddisfacendo sia alle relative norme CCIR, sia alle specifiche proprie dei personal computer, VGA, EGA, eccetera, in modo da permettere la rappresentazione dei due tipi di immagini su di un solo tipo di visualizzatore. A tal fine, esso genera sia le temporizzazioni proprie dello standard CCIR, per una risoluzione di 720 colonne per 576 righe, sia le temporizzazioni proprie della specifica VGA, per una risoluzione di 640 colonne per 480 righe, con un limite superiore di rappresentazione di piani grafici di 1024 colonne per 1024 righe.
