Real-Time Communication with WebRTC: Peer-to-Peer in the Browser

Deliver rich audio and video real-time communication and peer-to-peer data exchange right in the browser, without the need for proprietary plug-ins. This concise hands-on guide shows you how to use the emerging Web Real-Time Communication (WebRTC) technology to build a browser-to-browser application, piece by piece.

The authors’ learn-by-example approach is perfect for web programmers looking to understand real-time communication, and telecommunications architects unfamiliar with HTML5 and JavaScript-based client-server web programming. You’ll use a ten-step recipe to create a complete WebRTC system, with exercises that you can apply to your own projects.

• Tour the WebRTC development cycle and trapezoid architectural model
• Understand how and why VoIP is shifting from standalone functionality to a browser component
• Use mechanisms that let client-side web apps interact with browsers through the WebRTC API
• Transfer streaming data between browser peers with the RTCPeerConnection API
• Create a signaling channel between peers for setting up a WebRTC session
• Put everything together to create a basic WebRTC system from scratch
• Learn about conferencing, authorization, and other advanced WebRTC features
