The SD4105 is a 4 composite video inputs standard
definition DVB-T COFDM modulator which provides a
COFDM RF signal in range of 50-860MHz. The SD4105
is designed to achieve 576i/480i by using an MPEG2 
low latency encoding engine and state-of-the-art 
COFDM modulation technologies. It is an excellent 
choice to convert SD video/audio signals to digital
TV signals for distribution though your home or an
MATV system.
