Outline
NDS3394T V3 is a high performance and cost-effective DVB-T modulator designed by Dexin. It supports 24 or 16 FTA tuners input, maximum 128 IP inputs through DATA1 and 2 TS inputs for re-mux through 2 ASI input ports. After demodulating, multiplexing and DVB-T modulating, it outputs 8 non-adjacent carriers and 8 IP (MPTS) as mirror of carriers through DATA2.
NDS3394T is also characterized with high integrated level, high performance and low cost. This is very adaptable to a new generation broadcasting system.
