IRext Open Source IR Remote Control Library


Official Web Site

IRext Projects

IRext is an open source Infra Red Remote Control library with encoding and decoding algorithm and remote control databases

With IRext, you can easily get extremely compressed remote control code from web API and decode it in various environment including embedded devices, mobile phones, PC or even in your cloud servers.

A diagram below illustrates a typical architecture of user system with IRext.

Features :

  • All remote control codes are well verified.
  • All remote control codes are extremely compressed with encoding algorithm. Millions bytes of IR remote code is compressed into a single file within hundreds bytes.
  • All remote control codes could be decoded with a single set of algorithm.
  • Users can deploy private web console for IR remote code management.
  • Users can deploy private IR code indexing service to their back-end servers.
  • Decode algorithm consumes extremely low cost of RAM and CPU, even on 51 chips.
  • 14 categories of home appliances are supported (AC, TV, TOP Set, Net Box, IPTV, Stereo, Projector, Fan, Cleaning Robot, Air Cleaner, Light Bulb, DVD, Branded TOP Box and Dyson series).
  • Support up to 10000 types of remote controls.
  • Decode algorithm could be applied to various types of devices and OS (SCM, Linux, Windows, Java Web, Android, iOS, RaspBerry-Pi, Aduino, etc.).
  • Examples of decode algorithm is provided for various platforms.
  • Support decoding online (public web console) and decoding online with evaluation boards.
  • All IR codes and indexing data are being updated monthly.
