AirPlay is the screen mirroring protocol used by MacOS and iOS devices. AirServer provides AirPlay mirroring as well as audio only and video playback. AirPlay relies on Bonjour mDNS discovery.
AirPlay mirroring streams are encoded using H.264 video compression and transmitted as TCP packets. Resolution can be up to 1080p and Apple recommend a bandwidth of 25 Mbps per mirroring stream. Average bitrates will be significantly lower, depending on the content.
Latency for AirPlay on AirServer is around 150 ms under good network conditions.
Content protected with Digital Rights Management (DRM) such as (but not limited to) Netflix, Hulu, Amazon Prime and rentals from Apple cannot be transmitted over AirPlay mirroring for copyright and legal reasons. This is a limitation set by the content providers.
