DIGIVISION ha realizzato il sistema Gemini Multi HDTV / HDV che permette la riproduzione da 1 fino a 4 canali video HDTV (1920 x 1080 50i/60i ) o D1 ( 720 x 576 ) con overlay di grafica.
Gemini Multi HDTV / HDV e' l'unico sistema al mondo che permette la multivisione sincronizzata con la precisione del fotogramma di ben 4 video in formato HDTV / HDV.
Il collegamento ai videoproiettori puo' avvenire sia in DVI che in YUV HDTV.

Gemini e' stata testata con successo con i sistemi di videoproiezione dell'ultima geneazione da 25.000 ANSI Lumen progettati per le nuove sale cinematografiche digitali e in grado di proiettare immagini HDTV su schermi di 14 metri di base con un'altissima qualita' di immagine.
