The Fire TV Cube is an odd duck in the Amazon hardware lineup. Its primary function is as a set-top box streaming device like the Fire TV, Roku, and Apple TV. It brings Amazon’s operating system to the big screen (or any screen with an HDMI port, really) so users can stream popular services, like Netflix and Hulu and, of course, buy stuff from Amazon.
The differentiating feature is an array of infrared blasters, that allow it to act like a universal remote and control a collection of other devices that still require a physical remote control, like a DVD player or non-Wi-Fi TV. 4k
