Outline
This is a high performance and cost-effective QAM modulator designed by Dexin. It supports 16 DVB-C (DVB-T/-(T)/-S/-S2/S2X, ATSC, ISDB-T optional) FTA tuner input, maximum 512 IP input through GE1 and TS input for re-mux through 2 ASI ports. After multiplexing, scrambling and QAM modulating, it gives 16 non-adjacent carriers output and 1 IP (MPTS) output through GE1.
This is also characterized with high integrated level, high performance and low cost. It supports dual power supply (optional). This is very adaptable to newly generation CATV broadcasting system.
