DVBS2 to DVBT Transmodulator

Product Introduction

Trans-modulator is Softsolmedia’s all-in-one device which integrates demodulation, trans-mux and modulation (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, unit 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

* Demodulation + modulation + mixer modules in one box

* 2*2 QPSK S/S2 Tuner inputs

* 2*2 CAM with 2*2 CI-slot, one CAM can decrypt multiple programs

* ASI in/out with re-mux

* 1 IP (MPTS) output

* RF mixed in, RF mixed out (1*DVB-T /2*DVB-T/1*DVB-C/4*DVB-C Optional )

* LCN support (Logical Channel Number)

* Excellent modulation quality: MER≥42dB

* LCD display, Remote control and Firmware, web NMS management

* Updates via web

* Best quality and breakthrough price

           1*Module = 2*RF/Loop out + 2*CAM + 2*Smartcard
