An short introduction toWebRTC
Until now, some history
• Skype, MSN, Lync, video conference systems, Unified Communications (UC)– Definition UC: From one interface/screen switching modes of
communication without changing screens or devices
• Proprietary owned implementations– Manufactured exclusively by the owner of
intellectual property rights, as with a patent or trade secret.
• Expensive and not freely available
• Communication is server based
Initiative
• Promoted by Google Chrome team since 2009, the W3C webRTC WG and the IETF RTCweb WG
• Specification / W3C Editor's Draft 21 March 2014• WebRTC is open source project• Manage multimedia communications• Simple API’s in Javascript• Multi platform and multi device• WebRTC specs built into browsers (see http://
iswebrtcreadyyet.com/)• Now (2014) many suppliers offer WebRTC solutions and
numbers are growing.

Browser API’s for WebRTCBrowser supports WebRTC using API’s:
• GetUserMedia– To access and control microphone and
camera hardware– Must be allowed by user (opt-in)
• PeerConnection– Establish connection and set up context like
security and codecs
• DataChannels– Provide peer-to-peer connection– “Data part of WebRTC”
API = Application Programming Interface

Role of the Webserver
• WebRTC is a webservice webserver needed• Acts as the central control point• Webserver handles button clicked by user to join
video conference• Webserver is needed to establish the connection
between the browsers (peers)• Webserver does not handle the data part of the
communication between the browsers
