ZJ2406B DVB-(T) modulator is our 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.
