It is believed an Apple TV is going to included Siri and an iSight camera for FaceTime. It is believe Apple has made prototypes of the product. It may have a 27inch screen and looks just like the Apple Thunderbolt display. The screen can be mounted to the wall or stand on just a normal iMac curvy stand.
The Apple HDTV makes FaceTime calls using the built-in iSight camera. The camera is sophisticated, with facial recognition and the ability to zoom into the user’s face and follow them as they walk around the room. This allows users to make video calls from the couch across the room, rather than having to stand smack in front of the TV.
In addition, calls are initiated by Siri, the iPhone 4S’s virtual assistant. “[Apple] used Siri to make a FaceTime call,” a source said.
I think what will really make this machine great is the use of connecting a Mac to it. This will combine all apple products together to make 1 scren for you digital life.
