Digital TV Headend DVB-T Modulator,(DT-DVB-TM) is DAYTAI’s all-in-one device which integrates demodulation, trans-mux and
modulation in one case to convert signals into DVB-(T) 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) modulator also simultaneously supports adaptive linear and nonlinear digital pre-distortion.BISS function is
also embedded to descramble programs from tuner input.Power supply:AC 220V±10%,50/60Hz,Power Plug:European standard
Plug or American standard Plug is optional.
