WebRTC (Web Real-Time Communication) is your browser built-in technology with the aim to simplify developing applications using audio and video streams. You can easily build your own Skype in the browser using WebRTC. So the simple idea is that you open up a website and connect with another user immediately. WebRTC API includes camera and microphone capture, video and audio encoding and decoding, transportation layers, and session management.
