Multi-User Video Conference System

High-Performance Audio-Video Communication Solution Based on P2P Technology

Project Overview

Multi-user video conference platform based on WebRTC P2P technology, accessible via PC browser for online multi-user voice chat, single-user streaming, dual-user co-hosting, and video-on-demand features. All communications use P2P technology, significantly reducing server load and providing low-latency real-time communication experience.

Technical Challenges

Traditional video conference systems rely on centralized servers, suffering from high latency, high server load, and high costs, making it difficult to support large numbers of simultaneous users online.

Solution

Utilizes WebRTC P2P technology to implement peer-to-peer direct connections, with data transmission bypassing central servers, significantly reducing server load and transmission latency. Supports multiple communication modes to meet different scenario requirements.
