Microsoft has shown off Xbox One's built-in Twitch.tv functionality, which allows you to instantly broadcast your gameplay online.
The feature can be turned on simply by saying "Xbox broadcast", which brings up a Twitch.tv live panel at the side of your screen.
You can then see live text comments as people chat to you via your stream, check the number of people watching and other features.
The Twitch.tv features have been melded into the Xbox UI - there's no separate app to launch.
You can also record gameplay and edit it down via a simple interface, add on-screen graphics and upload it to the web.
