# Introduction

DJI i OSD is specially designed for DJI autopilot system during the FPV flight or other aero

- modeling activates. DJI i OSD

can transmit video and i OSD information in real time, which will help you to obtain the aircraft status information during a FPV flight. It can display power voltage, flight velocity, height, distance from the home point, horizontal attitude, GPS satellite number, etc. i OSD and video information are superposed on the receiver, making i OSD data clearly visible and bringing you a more involved flight experience.

DJI i OSD should be used in conjunction with a DJI autopilot system. It supports two video input sources under PAL or NTSC mode , which can be selected remotely by an R/C transmitter switch. The R/C TX switch can also chang e the wireless video transmitter channel remotely when us er uses the wireless video transmitter specified by DJI. The i OSD supports online upgrades. The i OSD has built

- in BEC, which is on one hand for the power supply of the camera, on the other hand for the power supply of the autopilot system’s main controller to improve the power supply reliability of the main controller.
