If you’re home and wanting to watch your video on the big screen, or simply want to use your TV speakers for audio, you can use AirPlay to connect with your Apple TV!
When you start watching a video or listening to audio, you will see the AirPlay logo available in the top right.
When you press the AirPlay logo, a passcode will appear on your screen for you to type into the pop-up on your phone. This is a security measure by Apple to ensure you have total control over the content showing through your Apple TV.
Once you verify the AirPlay passcode, your content will start playing on your TV!
