Valve has revealed SteamOS, an operating system based on Linux which is designed for video game consoles.
The company has also revealed that it'll also have two more announcements this week. You can see the countdown timer to the next one here.
Valve's website has the details, but the main added features straight from the site seem to be:
Valve says that "SteamOS combines the rock-solid architecture of Linux with a gaming experience built for the big screen."In-home StreamingYou 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, MoviesWe’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.Family SharingIn 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.Family OptionsThe 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.Cooperating systemSteam is not a one-way content broadcast channel, it’s a collaborative many-to-many entertainment platform, in which each participant is a multiplier of the experience for everyone else. With SteamOS, “openness” means that the hardware industry can iterate in the living room at a much faster pace than they’ve been able to. Content creators can connect directly to their customers. Users can alter or replace any part of the software or hardware they want. Gamers are empowered to join in the creation of the games they love. SteamOS will continue to evolve, but will remain an environment designed to foster these kinds of innovation.Fast forwardIn SteamOS, we have achieved significant performance increases in graphics processing, and we’re now targeting audio performance and reductions in input latency at the operating system level. Game developers are already taking advantage of these gains as they target SteamOS for their new releases.Living room & SteamFinally, you don’t have to give up your favorite games, your online friends, and all the Steam features you love just to play on the big screen. SteamOS, running on any living room machine, will provide access to the best games and user-generated content available.
Steam OS will be available soon as a free stand-alone operating system for living room machines.
