WebRTC (Web Real-Time Communication) is an API definition being drafted by the World Wide Web Consortium (W3C) to enable browser to browser applications for voice calling, video chat and P2P file sharing without plugins.

History

A project known as WebRTC, for browser based realtime communication, was open sourced by Google.[1] This has been followed by on going work to standardise the relevant protocols in the IETF[2] and browser APIs in the W3C.[3]

The W3C draft of WebRTC[4] is a work in progress with advanced implementations in the Chrome and Firefox browsers. The API is based on preliminary work done in the WHATWG[5]. It was referred as the ConnectionPeer API, and a pre standards concept implementation was created at Ericsson Labs).[6] The Web Real-Time Communications Working Group expects this specification to evolve significantly based on:

  • The outcomes of ongoing exchanges in the companion RTCWEB group at IETF[7] to define the set of protocols that, together with this document, will enable real-time communications in Web browsers.
  • Privacy issues that arise when exposing local capabilities and local streams.
  • Technical discussions within the group, on implementing data channels in particular.[8]
  • Experience gained through early experimentations.
  • Feedback received from other groups and individuals.

Design

As of March 2012 the IETF WebRTC Codec and Media Processing Requirements draft[9] requires implementations to provide PCMA/PCMU (RFC 3551), Telephone Event as DTMF (RFC 4733), and Opus (RFC 6716), along with a number of video codec minimum capabilities. The Peerconnection, Data channels and a media capture browser APIs are detailed in the W3C.
