Apple's AirPlay technology offers several benefits to those with an Apple TV and iOS device or Mac. You can stream your favorite music, podcasts, movies, TV shows, and more from your iOS device or Mac to your Apple TV. You can also use AirPlay to mirror the screen of your device to your Apple TV.
Sure, you can easily access iTunes and iCloud content directly on your Apple TV, but streaming through AirPlay allows you to see all the audio or video stored locally on your device ̵
You can also stream from apps and third-party services to your Apple TV, so screen mirroring can be useful for playing games and using other apps from your mobile device, a larger screen.
To stream audio or video, your device must be on the same Wi-Fi network as your Apple TV. You must also be signed in to the same iCloud account in all areas. To set up and use everything AirPlay has to offer.
