Valve have just announced that they are releasing a new operating system. Steam OS as it is going to be called, is an operating system designed for the TV and Living Room, and looks to build upon the Steam Big Picture mode.
Steam OS looks to be the main reason Valve have looked to port games to Linux, and seems that they have now reaped enough reward from that venture to announce they are going to do it themselves. New features also look set to be included in Steam OS as well as the main Steam client, such as:
In Home Streaming
You can play all your Windows and Mac games on your SteamOS machine, too. Just turn on your existing computer and run Steam as you always have - then your SteamOS machine can stream those games over your home network straight to your TV!
Music, TV, Movies
We’re working with many of the media services you know and love. Soon we will begin bringing them online, allowing you to access your favorite music and video with Steam and SteamOS.
In the past, sharing Steam games with your family members was hard. Now you can share the games you love with the people you love. Family Sharing allows you to take turns playing one another’s games while earning your own Steam achievements and saving your individual game progress to the Steam cloud.
The living-room is family territory. That’s great, but you don’t want to see your parents’ games in your library. Soon, families will have more control over what titles get seen by whom, and more features to allow everyone in the house to get the most out of their Steam libraries.
From the post, Valve have stated that AAA games will be announced shortly that will run natively on the new OS, however because of the in-home streaming features you will have access to the full catalogue of Steam games (all 3000 of them).
The most important part of this, announcement is that it is going to be completley free, allowing system manufacturers (such as ourselves) to cater hardware and products to it, rather than the hardware being locked down.
The Steam announcement page can be found at http://store.steampowered.com/livingroom/ with more updates scheduled in around 48 Hours.
