Apple released iOS 5 beta 3 for developers, some new features have been discovered. Beta 1 introduced a new feature for the iPad, AirPlay Mirroring which brings your iPad screen to your TV wirelessly via Apple TV.

Beta 3 now brings a new feature, FaceTime over AirPlay Mirroring. Check out the screenshot of the feature in action provided:

This brings a new element for FaceTime as it can now bring its video conferencing to the big screen. The next logical step would be to include group chat in the future, as this is already possible with iChat on the Mac.

Though for you to use AirPlay mirroring, you must have iOS 5 beta 3 installed on both your iPad and your Apple TV 2G, without that, this won’t work.

When the previous beta’s got out, many people tried AirPlay mirroring and posted good reviews about it. However, there was one little drawback. AirPlay mirroring didn’t support FaceTime, meaning that your calls could not be viewed on the big screen via AirPlay. Now Apple addresses that concern with iOS 5 beta 3, which brings FaceTime AirPlay mirroring support.

It remains to be seen whether the final version of iOS 5 will bring AirPlay mirroring support of FaceTime to end users, but if it does, it is definitely going to add a whole new dimension to video calls made using FaceTime.
