What is WebRTC? (2)

HTML5 already supports multimedia capability - no plugins

required

WebRTC adds in-browser

support for Real Time,

Encrypted, Bi-directional audio

and video

Support as of Aug

What is Driving WebRTC Adoption?

Put simply - the web user experience has been lacking real time

voice and video - WebRTC addresses that gap

Software is migrating rapidly to cloud / web based

BYOD works best with web-served applications

Bandwidth is ever increasing and ever less costly

WebRTC directly addresses the security and connectivity

challenges presented by the WWW for real time comms
