NDS3524C Encoder Modulator
NDS3524C encoder modulator is DEXIN’s all-in-one device integrating MPEG2 encoding and modulating to convert audio/video signals into DVB-C/T/ATSC/ISDB-T/DTMB RF out. It supports 1/4/8 HDMI inputs, and its pay-as-you-grow modular design and flexible configuration are making it extremely scalable, and very reliable with high performance. The signals source could be from STB, satellite receiver, closed-circuit television cameras and antenna etc. Its output signal is to be received by TVs or STBs etc.
