Outline
The modulator is a high performance and cost-effective DVB-T modulator designed by Kunuomagic. It has 8 DVB-S2 tuner inputs. After multiplexing, scrambling and modulating process, it gives 4 DVB-T carrier output through one RF port. To meet customers’ various requirements, this device is also equipped with data port for 128 IP input and 4 MPTS output over UDP and RTP. Its pluggable structure design greatly facilitats the change of modules as needed. Moreover, the four CAMs/CIs accompanied can descramble the programs input from 8 Tuner and IP input.
The modulator can be upgraded and controlled through network system, which allows it widely used in digital broadcasting network and provide good signals for scientific laboratory and DVB-T STB.
