When deploying a wireless screen mirroring solution,
Google Cast and AirPlay are two protocols that cannot be ignored. What are their differences, and how should you choose between them?
- Principle: The mobile phone acts as a remote control, sending “playback commands” to devices like Chromecast. The receiving device then pulls content directly from the network on its own.
- Analogy: It’s like you sending a video link to a friend, who then opens and watches it independently.
- Principle: The screen content of an iPhone, iPad, or Mac is encoded in real time and transmitted to the receiving device via Wi-Fi.
- Analogy: It’s like showing your phone screen to a friend via a live video call.
- Mobile device liberation: After casting a video, the phone can be turned off or used for other tasks without interrupting playback.
- Stable playback: Performance is not dependent on the phone’s network status, as content is streamed directly by the receiving device.
- Suitable scenarios: Casting online videos in smart classrooms; playing cloud-stored promotional videos in wireless meetings.
- Low latency: Real-time mirroring ensures almost no delay, critical for live operations.
- Completeness: Can mirror any on-screen content, including dynamic operations (e.g., app navigation, document editing).
- Suitable scenarios: Demonstrating apps or PPTs in wireless meetings; showing students’ tablet operations in smart classrooms.
- Primarily casting online videos? Google Cast offers a better experience.
- Need real-time demonstrations, operations, or group discussions? AirPlay or Miracast is essential.
Best solution: Choose a wireless screen mirroring device that supports Google Cast, AirPlay, and Miracast simultaneously to cover all application scenarios.
