4/8CH HD MPEG-2 Video DVB-C/T ATSC ISDB-T Encoder Modulator COL5188H2

COL5188H2 encoder modulator is our all-in-one device integrating MPEG2 encoding and modulating to convert audio/video signals into DVB-C/T/ATSC/ISDB-T RF out. It support 4 /8 HDMI inputs, and its pay-as-you-grow modular design (maximum support 8 HDMI inputs) and flexible configuration are making it 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.
