No there is not a DC FanDome app for your TV but if you have a Chromecast enabled TV or Apple TV you are still covered. The fact that the fan event is available via browsers means that you can utilize tab casting from Google Chrome to your TV. Apple TV devices can use AirPlay in conjunction with IOS devices and Mac Computers in order to project the footage to your TV in full HD.
And of course, the least elegant way to take it in, yet just as effective, would be to hook a computer to the TV via HDMI and view it directly from the source.
Any of these three methods will allow you to enjoy the event from your couch over lunch. Enjoy the show and stream on my friends.
