China Digital Headend DVB T2 Modulator, Find details about China DVBT2 Modulator, Digital Modulator from Digital Headend DVB T2 Modulator
SFT9307B DVB -T/T2 modulator is SOFTEL's all -in-one device which integrates demodulation, trans-mux and modulation in one case to convert signals into DVB-T/T2 RF output and IP output over UDP. The device equipped with 2 DVB-S/S2 tuner inputs, one GPS 10MHz input port and one 1PPS input port. The output modulated signals are to be received by TVs, STB and etc. This DVB-T/T2 modulator also simultaneously supports adaptive linear and nonlinear digital pre-distortion. BISS function is also embedded to descramble programs from tuner input.
