4IN1 ASI DTMB Modulator
Overview
4IN1 ASI DTMB Modulator has 4×ASI input and 4×DTMB modulating carrier output. Each carrier has independent signal channel encoding and direct RF output. One set of 4in1 DTMB modulator can work as 4 stand alone DTMB modulators, which significantly reduces the network operators’ head-end cost. It suits 1U rack and can be configured by front panel LCD and NMS (network management software).
