Is it possible to use FaceTime on an Apple TV?

It is not possible to use FaceTime directly on an Apple TV because the hardware lacks a camera and a native FaceTime app. However, users can leverage AirPlay, Apple's proprietary wireless streaming protocol, to mirror a FaceTime call from their iPhone, iPad, or Mac to the Apple TV. This method displays the video call on a larger screen but still utilizes the camera and microphone from the originating iOS device or Mac. This workaround provides the benefit of a larger display for group calls or a more comfortable viewing experience without having native FaceTime functionality embedded in the Apple TV itself.
