# Introduction

## **Introduction**

**HDMI Extender**, also called image transmission system, is designed for wireless transmission of high-definition HDMI audio and video signals from audio-visual devices to the display devices for high-definition playback. 

* The audio-visual devices include: the ones with HDMI connector like TV box, computer,  game console, DVD, camcorder, smartphone, VR etc.;
* The display devices include: the ones with HDMI connector like TV, projector, monitor etc.;

Adopting standard TCP/IP protocol, the high-definition audio and video signals are transmitted through wireless signal, which can realize point-to-point applications and one-to-many applications. It's equipped with excellent image processor and high-performance transmission system, making signal transmission more smooth and stable, and is a cost-effective way to extend HDMI signal wirelessly

### Features

* Aluminum alloy case, compact, light and thin design which is more beautiful than iron case;
* Max. resolution captured up to 3840\*2160\@30fps;
* Max. resolution transmitted up to 3840\*2160\@30fps;
* Built-in automatic adjustment system which makes the image more smooth, clear and stable;
* Built-in ESD electrostatic protection circuit, easy to install, plug and play;
