大家經常看到一些Xbox和Windwos Phone互動的影片，但就沒有實際看到有什麼東西出來(除了個Kinect的寵物Game，這都算是互動吧!)。現在，Microsoft的Windows Phone Blog就說給我們聽，這不再是影片裡的概念，我們將佢實現出來了。

而這個Companion App能夠做什麼呢:

• Finding Content: Just like on your Xbox, the Xbox Companion gives you instant access to the Xbox LIVE Marketplace catalog of games, movies, music and TV shows. I used it to search “Featured Content” and pulled up the X-Men: First Class.
• Learn more about what you’re watching, listening to, or playing: Once I found the movie and touched the movie tile, the Xbox companion app took me to an info page that has all the related details about. And the content is really rich, too – for example, when I swiped to the “cast” page and touched an actor’s name, like star James McAvoy, I was taken to other movies starring him. From there, I could easily learn more about the other movies, their cast, etc. It’s an infinite road of interactive content.
• Control & Play: Once I selected the content and hit play, the Xbox Companion flips into “controller mode” in which I could navigate my Xbox, or control video playback of your video. The best part here is that controls are virtually instantaneous – easily as fast as using my controller or a TV remote.

總括來說，是為更新後加入影片和電視功能的Xbox提供一個搖控。這是一個很好的開始，我們之前亦見過Windows Phone和PC Kinect互動(詳) ，希望之後能看到Xbox遊戲能和Windows Phone互動！
