DVB-T Modulator viigio

SDM-T1 is a composite video input standard definition DVB-T modulator which provides COFDM RF signal in range of 45-860MHz.
It is designed to achieve 576i/480i (PAL/NTSC) by using MPEG2 low latency encoding engine and state-of-the-art DVB-T modulation technologies.
It is an excellent choice to transport video/audio signals from TV satellite receivers, surveillance camera or video/media players to a LCD TV or set-top box.
It can be used in series with other SDM-T1 so the number of channels in the coaxial cable on the SMATV system can be increased as desired.
