Outline

NDS3343D is a high performance and cost-effective mux-scrambling QAM modulator designed by Dexin. It has multiple input ports optional. After multiplexing, scrambling and QAM modulating process, then it gives 4 RF output. To meet customers’ various requirements, this device is also equipped with IP port to output 4 MPTS over UDP. Its pluggable structure design greatly facilitates the change of modules (demodulator) as needed.

The four CAMs/CIs (Optional) accompanied and BISS modules can descramble the programs input from 4 Tuner inputs. Its pluggable structure design greatly facilitates the change of modules (demodulator) as needed. NDS3343D is also characterized with high integrated level, high performance and low cost. This is very adaptable to newly generation CATV broadcasting system.
