TiPB has discovered that in the third beta of iOS 5 a new featured has been activated. The feature is  AirPlay streaming support for FaceTime video calling, and allows  users to display FaceTime video calls directly on a large-screen TV for easy viewing by larger groups of people.

If this makes it into the final release — and not everything does — it’ll be fantastic for families and businesses alike.

The ability to easily start a video call and beam it onto the big screen is compelling. Whether it’s grandpa and grandma, or the team in England, it takes FaceTime from a small, personal experience to a big, group experience at the touch of a button.

This feature definitely adds will be useful for video calling in group settings. iOS 5 is expected to be released sometime in Fall.
