Outline

NDS3314 Tuner input mux-scrambling QAM Modulator is the latest generation mux-scrambling-modulating all-in-one device. It has 8 channel tuner (DVB-S2) and one channel ASI inputs. After multiplexing, scrambling and QAM modulating process, it outputs digital RF. To meet customers’ various requirements, this device is also equipped with IP port and 2 ASI out port to output TS. The device is also characterized with high integrated level, high performance and low cost. This is very adaptable to newly generation CATV broadcasting system.
