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. Originally implemented only in Apple’s software and devices, it 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, then AirTunes, was introduced in iOS 4.2 and was compatible with Airport Express.
Apple announced AirPlay 2 at its annual WWDC conference on June 5, 2017. It was scheduled for release along with iOS 11 in the third quarter of 2017, but was delayed until June 2018.Compared to the original version, AirPlay 2 improves buffering; adds streaming audio to stereo speakers; allows audio to be sent to multiple devices in different rooms; and control by Control Center, the Home app, or Siri,functionality that was only available previously using iTunes under macOS or Windows.
