AirPlay is a wireless streaming technology created by Apple that enables streaming of audio, video, and other content from Apple devices to compatible receivers such as Apple TV, smart TVs, and speakers. It operates over Wi-Fi, allowing users to mirror their device screens or play media through connected devices effortlessly.

AirPlay works with various Apple devices including iPhones, iPads, iPod Touch, and Mac computers. It also supports streaming to Apple TV, AirPlay-compatible smart TVs, and speakers. Recent updates have extended support to some non-Apple devices through AirPlay 2, increasing its compatibility across different platforms.

While AirPlay relies on Wi-Fi to connect devices, an active internet connection isn't always necessary for streaming locally stored media. However, streaming content from online services such as Netflix or Apple Music requires an internet connection for proper functionality.

Yes, with AirPlay 2, many smart TVs and speaker brands like Samsung, LG, and Sony have built-in support, allowing streaming from Apple devices even without Apple TV. This broadens AirPlay's usability beyond Apple's ecosystem.

If AirPlay isn't functioning properly, verify that all devices are connected to the same Wi-Fi network and have the latest software updates installed. Restarting both the streaming and receiving devices can help. If issues continue, check for interference from other networks or devices and consider resetting network settings to resolve connectivity problems.
