Features
Media Inter Connectivity
The Xbox One will allow instant and simultaneous access to movies, live TV, music, and Internet Explorer.Set-top box integration
Microsoft will introduce a feature that allows its next generation console take over a TV and set-top box in similar way to Google TV. The Xbox One will take a cable box signal and pass it through to the TV via HDMI, allowing Microsoft's console to overlay a UI and feature on top of an existing TV channel.Voice Control
The console will feature a similar, albeit richer set of voice control abilities than those found in the first generation Kinect. This will allow users to control Xbox functions via voice command. All voice control will be coordinated through the Kinect, and with this ability Skype will also become a function of the new Xbox.Controller
Kinect
The new Kinect will have "wake with voice" for the Xbox console. It will have a 1080p camera compared to the VGA sensor on the original Kinect. It employs a time-of-flight camera to acquire RGB-Depth data compared to the light coding technology (patented by PrimeSense) used in the original Kinect. The new motion controller would process 2 Gbit/s of data to accurately read its environment.The device will come with the console, the microphone will always be on, and will need to be plugged in for the console to function.
Operating System
The device will run three operating systems: Xbox OS, an OS based on the Windows kernel, and another OS that will allow the other two operating systems to communicate by virtualisation (as a hypervisor). Such integration will include features like snapped Skype calls while in game.
The Windows edition on the Xbox will not be compatible with standard Windows apps, though developers will be able to port them over with little effort.
XBOX Live
The Xbox Live service is scaled up to use 300,000 servers for Xbox One users from 15,000 that handle the Xbox 360 users. Cloud storage will be offered to save music, movies, games and saved content and developers will be able to use Live servers to offer more "living and persistent worlds."
