Introduction

OpenHD-Logo

OpenHD is a suite of software designed for long-range video transmission, telemetry, and RC control. While we originally designed it with hobbyist drones in mind, it can be adapted to a wide range of other applications as well.

What OpenHD Can Do

Our suite can transmit:

  • High definition video (with multiple cameras)

  • Two-way UAV telemetry

  • Two-way OpenHD telemetry (General settings, range-adjustments, channel-changes, wifi-modulation,...)

  • RC control signals

All of these signals can be sent over a single transmission channel and telemetry is using MAVlink to ensure high compatibility and stability.

OpenHD employs readily available Wi-Fi adapters, although not in the standard manner commonly associated with everyday Wi-Fi usage. To ensure low-latency and long-distance transmissions, we configure these adapters to function akin to analog video transmission hardware. This innovative protocol, inspired by befinitiv, has been reimplemented by OpenHD for optimized performance.

The configuration empowers OpenHD to transmit high-quality video and other signals across significant distances while maintaining minimal latency.

QOpenHD App

We offer a multi-platform app with a customizable on-screen display (OSD) for live video. The app is designed to work seamlessly with our suite, and allows you to easily view and control your OpenHD transmission.
