The main technology behind video conferencing tools is real-time communications (RTC) technology, which enables audio and video transmission over the internet with low latency. Protocols like WebRTC (Web Real-Time Communication) are commonly used to facilitate peer-to-peer connections, allowing users to communicate without needing to install additional software. These tools leverage high-quality audio and video codecs to optimize performance and ensure a seamless experience. Moreover, features like screen sharing, virtual backgrounds, and chat functionalities enhance user engagement during meetings. Overall, RTC technology has revolutionized remote communication, making virtual collaboration more accessible and effective.
