Article: In order to use AirPlay, you will need an iPad 2 or newer, as well as a second generation Apple TV or newer. Your iPad and your Apple TV must also be on the same Wi-Fi network. You should update your iPad's software before streaming to make sure that you get the best possible quality. You can disconnect the movie at any time by tapping the AirPlay icon (or Screen Mirroring icon) again, or by turning off your iPad's Wi-Fi.

What is a summary?
Make sure you have the right equipment. Enjoy your movie.
