participants appear within the web page itself. With OpenTok's APIs enabled, the web page "listens" and detects video streams from participants' web cameras. Video is controlled in the cloud by media servers which decide how to route the call to appropriate web pages, via Flash. A set of master controls lets the site owner manipulate the prominence of individual participants. Importantly, no plug-in is required by users. They simply click "Join call" or whatever prompt the web site owner implements to invite participants. Categories: Deals & Financings, Live Streaming, Technology
