1.2 GENERAL DESCRIPTION
The machine is a composite video input standard definition DVB-T 4 route
modulator which provides COFDM RF signal in range of 50-860MHz.
It consists of A/D, Coding, Modulation, Frequency conversion which provides
bandwidth of 6/7/8MHz to select.
It is designed to achieve HD input, and it can also supports standard H.264
encoding.
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 modulator so the number of channels in
the coaxial cable no the SMATV system can be increased as desired.
