Product 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
* 6 GE ports:
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
