Sega Model 3 UI Changelog:
We are thrilled to announce the long-awaited major update for Sega Model 3 UI, which fully integrates all features of the dedicated streaming client "StreamReceiver"! 🎉
Previously managed separately, streaming reception, controller/audio/video relay, and real-time chat functionality have now been beautifully unified into a single UI. Directly connect to active host servers, watch and play games, and engage in heated communication with other players, all within the tool itself!
🔥 Key Features & Integrations
🌐 New "Remote" Tab with Cyber UI Design
Added the newly designed "Remote" tab to the main interface. Leveraging Firebase as the backend, you can now view, monitor, and connect to active hosting servers with real-time updates on slot availability and connection status.
⚡ Real-Time Streaming & Ultra-Synchronized Input (Low Latency)
Video & Audio Streaming: Natively integrated VideoReceiver, AudioReceiver, and DxRenderer to receive and sync game visuals and audio from the host with extremely low latency.
Confirmed remote play with a measured latency of just 28ms in Japan-Hong Kong / Hong Kong-Japan (2,550km) tests.
Controller Input Relay: Seamlessly and rapidly relay client-side input operations back to the server. Enjoy remote versus and co-op plays without any discomfort or lag.
Hybrid Connections: Supports one-click switching between WAN (Internet) and LOCAL (LAN) modes. With built-in UPnP port mapping, the optimal network path is automatically secured based on your environment.
💬 Chat Overlay Functionality
Equipped the game window (VideoForm) with a real-time chat overlay in the upper right corner.
Simply press Enter in-game to instantly expand the chat input field, allowing you to exchange messages with other players and spectators without interrupting your gameplay.
🔄 Background Version Auto-Synchronization
Upon startup, the client automatically cross-references with the version management key located at the Firebase root. This prevents connection issues caused by outdated, incompatible versions and ensures you always have the latest client environment.
