Product Introduction
XLD3542 trans-modulator is Xielide’s all-in-one device which integrates demodulation, trans-mux and modulation (DVB-C, DVB-T, ISDB-T or ATSC optional) in one case to convert satellite signals into digital RF output. Its pluggable structure design greatly facilitates the change of modules (RF/HDMI/CVBS/SDI/YPbPr/…) as needed. The unit in this sheet is a 1-U case which supports 4 DVB-S/S2 RF inputs with 4 CAMs/CI accompanied to descramble the encrypted satellite signals. The CAM requires NO unsightly external power cords, cables, or additional remote control device.
To meet customers’ various requirements, NDS3542 is also equipped with 1 ASI input, and output with 2 ASI ports and 1 UDP IP port.
The output modulated signals are to be received by TVs, STB and etc with corresponding standard
Key features
