⮞ How screen sharing work ?
Screen sharing works by capturing your device’s display in real time and transmitting it over the internet so others can view it. The software records your screen, compresses the video using codecs like H.264 to reduce data size, and sends it through secure network protocols such as WebRTC. On the receiver’s side, the stream is decoded and displayed instantly. Most apps, like Zoom or Google Meet, allow users to share an entire screen or a specific window. Screen sharing is encrypted for privacy and optimized to maintain smooth performance even on limited bandwidth connections.
⮞ How Screen Sharing on iPhone Works :
Screen sharing on an iPhone allows users to display their screen content in real time during video calls, online meetings, or presentations. When you enable screen sharing, iOS captures everything visible on your screen — apps, photos, or web pages — and compresses it into a live video stream using advanced encoding technology. This stream is securely transmitted over the internet through protocols like WebRTC. The receiver’s device decodes the stream and displays it instantly. Apple ensures privacy with permissions and encryption, so only authorized participants can view your screen. It’s a seamless, secure way to collaborate or troubleshoot remotely.
