Microsoft is unveiling its Xbox Video web service today, ahead of a planned app release for Windows Phone. The web version, available at video.xbox.com, provides the same access to TV shows and movies as the existing Xbox Video app for Windows 8.1, and is designed as a replacement for the companys Zune video service. Its similar in layout to the Xbox Music web version, and you can stream content straight in the browser using Microsofts Silverlight plug-in. If youve already purchased content using the Windows 8.1 app or on an Xbox One then its available immediately for streaming.
