Product Introduction
HD IRD is Softsolmedia’s new design device. It can receive signals from 2 tuners (DVB-C, DVB-T/(T2), DVB-S/S2/S2X, ATSC-T, ISDBT optional). After demodulating, de-scrambling, re-multiplexing and decoding, it gives content out through various video/audio interfaces. Its video/audio outputs 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, NDS3975B is also equipped with ASI and IP input for re-mux, and output with 2 ASI ports and IP port.
