Infrared (IR) has been used in various consumer electronics since the 1980s. It was even used in smartphones and PDAs in the late 1990s and early 2000s. But IR abruptly died off in light of newer smartphones, mobile operating systems and better methods of transferring data between two mobile devices.

This year, several OEMs have come forward with flagships bearing IR blasters along their top edges. The HTC One and Samsung Galaxy S 4, for example, both come with infrared capabilities. And using the respective applications on each, you can point towards your entertainment system and control the various devices – a television, set top boxes, game consoles and more.

How do you set something like that up, you ask? It’s actually quite simple. And assuming you have the right electronics, it should only take a few minutes. Have an HTC One or Galaxy S 4? Be sure to check out the video below to find out how to use your smartphone as a TV remote!
