Technical Fundamentals of Google Duo Screen Sharing

How Screen Sharing Works

Google Duo‘s screen sharing technology operates using Android‘s native screen capture API. When activated, the app creates a secure virtual display that captures everything visible on your screen. This captured content is then:

1. Compressed using efficient video codecs (primarily VP9)
2. Encrypted end-to-end using WebRTC security protocols
3. Transmitted through Google‘s optimized network infrastructure
4. Decoded on the recipient‘s device in near real-time

This entire process happens with remarkably low latency – typically between 200-500ms under optimal conditions, according to performance testing by mobile tech analysts.
