Telecomponents Mod.TL4201 DVB-T Modulator/Encoder
Over view 4201(4203)(4205) 4IN1 MPEG-2 DVB-T(DVB-C)(DTMB) Modulator supports SD MPEG-2 video and MPEG-1 audio encoding and qam/dvb-c modulation. It has 4×CVBS video, 4 pairs of unbalanced audio and 1×ASI (BNC (MUX) input interfaces, and can multiplex the input (TS) to generate DVB-T/C RF signal output. It suits 1U rack and can be configured by front panel LCD and NMS (network management software). Its high-integrated and cost-effective design makes it widely used in varieties of digital distribution systems such as cable TV digital head-end, satellite digital TV broadcasting and terrestrial digital TV, etc.
