QAM Modulating Signal,Satellite RF signal ,Terrestrial Digital TV broadcasting RF signal input, 3 ASI output
TL100 Series DTV De-modulator
TL100 series products is new generation DTV demodulator developed by BeijingCircLoop Digital Image Tech. Co., Ltd. Independently, it converts the territory broadcasting signal of DVB-C ,DVB-S/S2 and national standard(GB 20600-2006)to ASI signal and output it.
It is modular and pluge-in plate structure , multiple confirguration can be assembled flexibly;the network management is based on web browser, it is easy to operate and maintain.
