Microsoft has posted a press release on their new Smartglass app, which will be officially released on the 26th October.
On Windows Phone 8 and Windows 8 there will be expensive integration to send currently playing media to and from the Xbox 360, and that also includes browser sessions
The app supports:
Navigation: Your phone and tablet will become the best remote controls in your house. Use the touch screen on your smartphone or tablet to control your Xbox 360 and use your devices to pause, rewind, or advance entertainment. (Available when SmartGlass launches)
TV & Movies: With Xbox Video, start a TV show or movie on your tablet and finish it on the big screen through Xbox 360; get real-time updates on the cast and crew for the film you are watching, discover related films, get unique bonus features with films from Xbox Video. (Available when SmartGlass launches). And coming next season, HBO GO’s "Game of Thrones" will offer groundbreaking Xbox SmartGlass experiences. (This is the only HBO GO program we’re announcing at this time)
