Users can use AirPlay to watch videos on their TV by playing from their Mac, iPad, iPod touch, or iPhone.
To stream videos, users should:
Connect their device to the same Wi-Fi network as their Apple TV or AirPlay 2-compatible smart TV.
Find the video that they want to stream.
Tap the AirPlay icon.
Choose their Apple TV or AirPlay 2-compatible smart TV.
To stop streaming, they will need to tap the AirPlay icon in the app that they're streaming from, then tap their iPhone, iPad, Mac, or iPod touch from the list.
They can also use mirroring instead of AirPlay to stream your content.
NOTE: Some TV manufacturers have integrated AirPlay 2 directly into their TVs, so you can share or mirror almost anything from your iOS device or Mac to your AirPlay 2–enabled smart TV.
You can find the list of devices that support AirPlay 2 on this list: AirPlay 2–Enabled TVs and Devices. If your smart TV or device doesn't appear on the list, it means that you cannot use it to cast content from the site.
Troubleshooting
Please know that AirPlay relies heavily on network connection. Poor connections or firewalls can prevent AirPlay from successfully casting. We highly recommend you check out Apple's documentation on AirPlay: Apple Help Center
