AirPlay is a proprietary protocol developed by Apple for streaming audio, video, and other media between devices over a local network. AirPlay allows users to wirelessly stream content from an Apple device, such as an iPhone or iPad, to an AirPlay-compatible receiver, such as an Apple TV, AirPort Express, or AirPlay-enabled speaker. AirPlay uses a combination of Wi-Fi and Bluetooth to transmit the audio and video data, and can support high-quality audio and video streams with low latency. AirPlay is supported by many popular audio and video apps, and is often used for streaming music, videos, photos, and other media from an Apple device to a larger display or speaker system.
