Overview
NDS3348TS (NDS3348CS) is a high performance and cost-effective DVB-T (DVB-C optional) modulator designed by Dexin. It supports DVB-S2 (DVB-(T) optional) tuner inputs, after multiplexing, scrambling (only for DVB-C) and modulating process, then it gives 4 RF output. To meet customers’ various requirements, this device is also equipped with 128 IP input and 4 MPTS output over UDP and RTP. Its pluggable structure design greatly facilitates the change of modules as needed. Moreover, NDS3348TS (NDS3348CS) can support Biss descrambling and can be upgraded and controlled through network system, which allows it to be widely used in setting up digital broadcasting network and provide good signals for scientific laboratory and DVB-T STB. Key Features: 12 DVB-S2 FTA Tuner input ports---Version I; 12 DVB-(T) Tuner input ports---Version II; 8 DVB-S2 FTA tuner+ 4 DVB-(T) tuner input---Version III; 8 DVB-(T) FTA tuner+4 DVB-S2 tuner input---Version IV; Support maximum 128 IP input(MPTS/SPTS) over UDP and RTP protocol; Support Biss descrambling; Support 4 groups multiplexing +4 groups DVB-T modulating----NDS3348TS
