NDS3304A 4 in 1 DVB-T Modulator

NDS3304A is a cost-effective DVB-T modulator developed according to DVB-T (EN300744) standard. It has 128 IP inputs. After multiplexing and modulating process, it gives 4 DVB-T non-adjacent carriers (50MHz~960MHz) output through the RF output interface. To meet customers’ various requirements, this device is also equipped with data port for 4 MPTS output over UDP and RTP. This is very adaptable to newly generation DTV broadcasting system.
