How can I cast content to Apple TV?

To cast content to an Apple TV, ensure both the Apple TV and the iOS device or Mac are connected to the same Wi-Fi network. On an iOS device, access the Control Center and tap "Screen Mirroring," then select your Apple TV from the list of available devices. For Macs, click on the AirPlay icon located in the menu bar at the top of your screen, and choose the Apple TV you wish to cast to. If prompted for a code, enter the AirPlay passcode that appears on your TV screen. You can also use AirPlay within specific apps by clicking on the AirPlay icon when it's available in the app's video player. Once connected, the content will be mirrored, or cast onto your Apple TV, allowing you to enjoy it on a larger screen.
