Overview
NDS3304T IP DVB-(T) modulator is a Multiplexing-modulating all-in-one device developed by DEXIN. It has 4 multiplexing channels and 4 DVB-(T) modulating channels, and supports maximum 1024 IP inputs through 4 data ports and 4 non-adjacent carriers output through 2 RF output interfaces. The device is characterized with high integrated level, high performance and low cost. This is very adaptable to newly generation DTV broadcasting system. Key Features: 4*RJ45, 2*SFP, DATA1/2 and SFP1/2 for input, DATA 3/4 for output; 4 DVB-(T) non-adjacent carriers output, fully complying with EN302 755; Max 840Mbps and 1024 IP inputs for each GE input; Supports multiplexing with accurate PCR adjusting, PID remapping and PSI/SI editing; Supports up to 256 PID remapping per channel; 2 IP (MPTS) output over UDP protocol; Supports single PLP; Support MISO and SISO; Supports non-linear digital pre-distortion (DPD); Support PID bypass and pass-through; Support Web-based Network management; 6 GE ports: Specifications: 4*RJ45, 2*SFP, DATA1/2 and SFP1/2 for input, DATA 3/4 for output; Max 1024 IP input through data ports 1/2, 100/1000M Ethernet Ports (RJ45 1/2 and SFP interface 1/2 alternative)
