AirPlay is a proprietary wireless communication protocol stack/suite developed by Apple Inc. that allows streaming between devices of audio, video, device screens, and photos, together with related metadata. It was originally implemented only in Apples software and devices, and was called AirTunes and used for audio only. Apple has since licensed the AirPlay protocol stack as a third-party software component technology to manufacturers that build products compatible with Apple's devices.
AirPlay allows you to stream media between Apple and smart devices. You can AirPlay from an iPhone, iPad, or Mac to an Apple TV or AirPlay-compatible smart TVs and speakers. For AirPlay to work, both devices have to be on the same Wi-Fi network or within Bluetooth range. AirPlay can be used to stream videos, photos, music, and more from Apple devices to your Apple TV, favorite speakers, and popular smart TVs.
AirPlay can be used to stream video or mirror the screen of your iPhone or iPad. To stream video manually from an iPhone or iPad, you need to connect your device to the same Wi-Fi network as your Apple TV, AirPlay-compatible smart TV, or Mac. Then, find the video that you want to stream and tap the AirPlay button. To stop streaming, tap the AirPlay button in the app that you're streaming from, then tap your iPhone or iPad from the list.
AirPlay is a feature that allows Apple devices to share media like videos, images, and music to AirPlay-enabled TVs, speakers, and other devices, as long as they're all within the same network. This means AirPlay can only work if both devices are connected to the same Wi-Fi network, within Bluetooth range, or connected to the same router using an ethernet cable.
