Introduction of HD-MI DVB-T Transmitter Receiver :
DVB-T transmitter is a full HD 1080P COFDM wireless video audio transmission system, with HD-MI video interface. DVB-T transmission system adopts the latest COFDM modulation, which supports mobile video transmission with stable and robust signals, and requires much narrower bandwidth. COFDM digital system also resist to multi-path, and anti-jamming. COFDM DVB-T digital transmitter performs well inside buildings, through walls, and around corners (NLOS: non line of sight transmission), and is also high performances on aircraft (UAV, UGV, drone, helicopter, etc.), vehicles, ships under high speed mobile condition.
