WebRTC, Web Real-Time Communications, is revolutionizing the way web users communicate, both in the consumer and enterprise worlds. WebRTC adds standard APIs (Application Programming Interfaces) and built-in real-time audio and video capabilities and codecs to browsers without a plug-in. With just a few lines of JavaScript, web developers can add high quality peer-to-peer voice, video, and data channel communications to their collaboration, conferencing, telephony, or even gaming site or application. Written by experts involved in the standardization effort, this book introduces and explains the W3C APIs and the IETF protocols of WebRTC. Packed with figures, example code, and summary tables, this book makes complicated concepts and technologies such as peer-to-peer media and NAT and firewall traversal easy to understand.
