AirPlay is a proprietary protocol stack/suite developed by Apple Inc. that allows wireless 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.
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.
Mirror can send the screen content of the iPhone or the screen content of the Mac to the Airplay receiver via the network, and send the sound of the microphone of the iPhone or Mac to the Airplay receiver via the network.
In this way, the content displayed on the sender and receiver is consistent.
In Picture mode, the sender can transmit photos to the receiving end through the network. In this case, the receiving end only displays Picture, and the display content may be inconsistent with the sending end.
This mode is only supported by the iPhone, and after iOS9, this mode has been canceled.
In the video and music mode, the sender can transmit the URL of the content to the receiving end through the network.
In this case, the receiving end can play the related content through the URL.
In this mode, the sender and receiver display content is inconsistent. The sender can operate by itself without affecting the content of the receiver.
The sender needs an iPhone or Mac.
The sender and the receiver need to be on the same network segment.
