**Imagine a world where your phone, TV and computer could all communicate on a common platform. Imagine it was easy to add video chat to your web application. That's the vision of WebRTC.** WebRTC implements open standards for real-time, plugin-free video, audio and data communication. As Brendan Eich put it: "WebRTC is a new front in the long war for an open and unencumbered web." We believe WebRTC can democratise and decentralise tools for content creation and communication -- for telephony, gaming, video production, music making, news gathering and many other applications. In this session show you how to use WebRTC to build real-time communication into your web apps: what are MediaStream, PeerConnection and DataChannel? how does WebRTC signalling work? what are ICE, TURN and STUN? what do I need server-side for WebRTC?
