🔹 What is Google Cast? (Definition)
Google Cast is a wireless streaming protocol developed by Google that allows users to send (cast) audio, video, or screen content from a phone, tablet, or computer to a compatible TV or speaker.
It powers devices like Chromecast and is built into many smart TVs and speakers under the branding “Chromecast built-in.”
🔧 How Does Google Cast Work?
✅ Basic Concept:
You control media from your device, but the actual playback happens on the TV or speaker, using its own internet connection.
✅ Steps to Cast:
- Connect both devices to the same Wi-Fi network.
- Tap the Cast icon 🔊📺 in supported apps like YouTube, Netflix, or Spotify.
- Choose the target device (TV or speaker).
- Your phone becomes the remote, and content plays on the big screen or speaker.
