Product Introduction
NDS3975C is professional HD IRD which receives signals from satellite and gives content out through various video/audio interfaces after demodulating, de-scrambling, re-multiplexing and decoding. The output video/audio support HDMI, CVBS, SDI, BNC, XLR interface and SPDIF.
The two CAMs/CIs accompanied and BISS modules can descramble the programs input from encrypted Tuner, ASI and IP.
Its pluggable structure design greatly facilitates the change of modules (demodulator or decoder) as needed.
To meet customers’ various requirements, NDS3975C is also equipped with ASI and IP input for re-mux, and output with 2 ASI ports and IP port.
