The Portable FPV System with Smartaudio is a method used simply to control a radio-controlled vehicle specifically those that use Unmanned Aerial Systems (UAS) or other type of Unmanned Aerial Vehicles (UAV) in the driver or Pilot’s view point. Incorporated to the system is a special feature called Smartaudio. Smartaudio is a type of VTX telemetry protocol in which it is a combination of an audio signal and a digital control signal. The two said signals are combined together to one simple audio signal. This signal can be used to control the VTX or Video Transmitter. And it is a simple serial signal. This basically allows the Pilot of the UAV to change settings for video transmitter via the On Screen Display (OSD) menu. So having Smartaudio feature makes things like switching VTX channels, power levels less difficult for Pilots, with no need to push switches or obscure push button menus. When pilots switched over to this system that supports Smartaudio it is seen just how quickly it can change multiple settings using OSD, giving more freedom and accessibility.
