Steam Link video shows you how it works
Valve has sent over a video giving you short look at how Steam Link works.
How it works is you plug Steam Link to a TV and the home's network and voila - you can play your Steam library of games on your couch.
Steam Link will work with a wireless or wired connection, which is handy for those without a great ISP.
You can find out more on Steam Link on the Steam Store where specs are also posted.
Steam Link is up for pre-order and it will run you $50 for the base unit. You can also purchase it packed with the Steam Controller for $99.98.
It's out on November 10.
