When exploring the world of wireless screen mirroring,
Google Cast is an indispensable key technology. What exactly is it? And how does it differ from ordinary screen mirroring?
Google Cast is a technical protocol launched by Google. It allows users to cast audio and video content from mobile phones, tablets, or computers to devices that support this protocol (such as Chromecast and smart TVs) for playback.
Unlike Miracast (which fully mirrors the phone screen), Google Cast mainly operates in two modes:
- Principle: When you tap the “Cast” button on apps like YouTube or Netflix, your phone actually only sends a “playback command” and a video link to the Chromecast device. The Chromecast then fetches and plays the content from the internet on its own.
- Advantages: During this process, you can turn off your phone’s screen, make calls, or run other apps—all without interrupting the TV playback. This mode is also very power-efficient.
You can also mirror the entire phone screen to the TV. In this case, the operation is similar to Miracast, but latency and stability may vary depending on the network.
Google Cast is a crucial part of building a multi-screen interaction ecosystem. With its user-friendly “casting” mode, it greatly optimizes the sharing experience of media content like videos and music. Together with technologies such as Miracast and AirPlay, it enriches the options for wireless screen mirroring.
Google Cast is an efficient and intelligent content casting protocol, especially suitable for media playback. It is a powerful tool for achieving seamless multi-screen interaction.
