The Lightbridge 2.4G Full HD Video Downlink with OSD and Control from DJI is designed to provide a complete FPV wireless relay solution, combining the video downlink, OSD (on screen display) data, and control signal in one system. It features two key components, one for the air end and one for the ground end. The air end component is a module that installs in or on the aircraft and features HDMI and composite video inputs. It also communicates with the flight computer, sending pilot inputs from the radio controller (transmitter) to the flight controller and receiving flight data from the instrumentation for the sake of the OSD. The air end module can also send a control signal to the gimbal for in-flight operation of camera movements.
