DMB-2100 DVB-T2 Modulator is newly designed with advanced encoding and modulating technology. 
Compliant with DVB-T2 standard, it can make better using of the limited terrestrial bandwidth sources and provide more than 50% capacity compared with the previously DVB-T standard. It equipped with Mode A(single-PLP) and MI(T2-MI) interface, it also be able to receive transmission data and synchronous information from DVB-T2 Gateway via ASI and IP connectors. Moreover, it can be applied to both MFN and SFN system with 1PPS and 10MHz reference clock interface. Excellent performance and features enable this advanced DVB-T2 Modulator to wide applications in the even-increasing needs of HD/SD programs and developing DVB-T2 system etc.
