1.2 GENERAL DESCRIPTION
This is a composite video input standard definition DVB-T HD
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 only supports stan-
dard H.264 encoding.
It is an excellent choice to transport HD signals from TV satel-
lite 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.
