NDS3344C IP QAM Modulator
Outline
NDS3344C IP QAM modulator is an all-in-one device integrated with multiplexing, scrambling and modulation in one case. It supports 192 IP (SPTS/MPTS) input over UDP/RTP with 4 Ethernet FE ports and 1 GE port. After multiplexing, scrambling and modulating process, it gives 4 DVB-C adjacent carriers (30MHz~1000MHz) output through the RF output interface. To meet customers’ various requirements, this device is also equipped with 1 data port for 4 IP (SPTS/MPTS) output over UDP protocol.
With the features of low cost and high performance, NDS3344C is very adaptable to IPTV system
