A Chromecast is a cool little device cooked up by Google to bring Smart TV capabilities to TVs that don’t have them. It connects to the TV through an HDMI input and to the outside world via your home WiFi. Once it’s been set up programs and apps on the same network as the Chromecast pick up its presence and make playback (or “casting” as it’s called) on it available.
Choosing to cast a video means that instead of starting playback on the screen of your computer, tablet or smartphone the job is passed on to the Chromecast that shows the content on the flat screen TV.
Thanks to an open API developers are free to build Chromecast support in to their programs and apps which means that the number of supported applications is measured in thousands and is constantly increasing. Not surprisingly, this list has also come to include most of the current Popcorn Time developers and it even supports subtitles.
If you prefer Apple to Google, an alternative to a Google Chromecast is the Apple TV which also works with Popcorn Time.
