Architecture for Real Time Communications over the Web

The emergence of HTM L5 and other associated web technologies can shape a diversity of future applications, where the client-server operations will be obsolete. In particular, the Media Capture and Streams API of HTM L5 enables third party access to multimedia streams fro m local devices. Enriched with a WebSockets imp lementation, a web application can commun icate, stream and transfer media or other data to its clients at real t ime to support a full collaborative environment. In this paper, we introduce an arch itecture that capitalizes on the above technologies to enable real time co mmunicat ions over the web. We also demonstrate the web applications we have developed in this context for live video streaming and web video chat with no requirement for any plug-in installation.
