As was anticipated, the new Xbox One will function as a set-top cable box, allowing users to switch between TV and gaming video by voice command.

In today's Xbox One reveal, the console was shown swapping between DVD/streaming video playback, the cable input, a video game, and its Internet functionalities.

A voice-activated television guide will support the feature. Xbox Guide, as it is called, allows a user to quickly navigate the guide by voice command, calling out titles of shows and channels. The guide also will keep track of a user's favorite programming, and shows trending elsewhere.
