Outline
NDS3542D multi-input modulator is DEXIN’s all-in-one device which integrates demodulation, trans-mux and modulation in one case to convert signals into RF output. It is a 1-U case which supports 4 tuner inputs to receive signal from satellite, cable or terrestrial. To meet customers’ various requirements, NDS3542D is also equipped with 2 ASI input, and output with 2 groups separate ASI ports and 2 MPTS UDP IP port. The output modulated signals are to be received by TVs, STB and etc.
The USB port is designed to record encoded video (TS) and save it in ts files in the USB Keys or Hard Disks, and then the ts files can be playback through the USB port.
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.
