The biggest leap came in 2018 with AirPlay 2, which introduced multiroom audio capabilities, improved buffering, tighter smart home integration, and Siri voice control. This evolution transformed AirPlay from a basic streaming tool into a comprehensive wireless entertainment platform.

AirPlay vs generic "casting"

While AirPlay serves a similar purpose to technologies like Google Chromecast and Miracast, it's distinctly different in its approach and ecosystem. AirPlay is optimized exclusively for Apple devices and officially licensed third-party products, ensuring consistent performance and seamless integration. Chromecast works on iOS and Android, while Miracast supports various Windows and Android devices. However, AirPlay's tight integration with Apple's hardware and software delivers a more polished, reliable experience for users invested in the Apple ecosystem.

How AirPlay Works

Sender and receiver devices

AirPlay operates with two types of devices: senders and receivers. Sender devices include iPhones, iPads, Macs, and iPod touch models that initiate the streaming. Receiver devices accept the wireless signal and play the content, including Apple TV boxes, AirPlay-enabled smart TVs from brands like Samsung and LG, wireless speakers from Sonos and Bose, and AV receivers from Denon and Marantz. This sender-receiver relationship underpins AirPlay's functionality, requiring both ends to be compatible.

Connection technology

AirPlay uses your home Wi-Fi network as its primary connection method, allowing devices to communicate over it. Alternatively, it can establish peer-to-peer connections directly between devices when a shared network isn't available. Devices discover each other through Apple's Bonjour service, which automatically detects compatible receivers on the network. Bluetooth assists with the initial handshake and device discovery, while the actual media streaming occurs over Wi-Fi for better bandwidth and quality.

Streaming vs screen mirroring

AirPlay offers two distinct modes of operation. Streaming mode sends only the media file (music, video, or photos) to the receiver while your device remains free for other tasks like browsing or checking messages. Screen mirroring, on the other hand, duplicates everything on your device's screen in real time, including apps, notifications, and interactions. This makes streaming ideal for extended playback sessions, while mirroring works better for presentations, demonstrations, or sharing content that isn't in a dedicated app.

Data transmission

AirPlay transmits various types of digital content wirelessly between devices. It handles audio files, video streams, photos, and associated metadata like track titles, album artwork, and playback controls. The technology uses Real-Time Streaming Protocol (RTSP) as its foundation for reliable media delivery. For audio transmission, AirPlay can use the Apple Lossless Audio Codec (ALAC) in some implementations, potentially delivering high-quality sound that rivals wired connections. The actual quality depends on network conditions and the capabilities of both sender and receiver.

AirPlay vs AirPlay 2

What is AirPlay 2

AirPlay 2 launched in 2018 as a significant upgrade to the original protocol, addressing long-standing limitations and user requests. This newer version focuses on multiroom audio capabilities, allowing you to play music across multiple speakers simultaneously throughout your home. It features improved buffering technology for more stable connections, reduced audio dropouts, and better synchronization. AirPlay 2 also integrates deeply with Apple's Home app for smart home control and supports comprehensive Siri voice commands for hands-free operation.
