[edit] Overview
RealMedia or RealOne or RealSystem was known as RealAudio and RealVideo in its earlier version history. It started out as an audio-only streaming architecture. As RealNetworks' cross-platform, multimedia software architecture, RealSystem is used to publish video, sound, graphics, text, music, SMIL, or Flash files over the Internet with an RTSP "true streaming" server. RealSystem displays and plays digital media through an application called the RealOne Player. There is a free version (Basic) and a feature enhanced version (Plus) (US$30) which adds presentation capabilities to the basic version.
Reference this web page for an overview of the RealSystem Architecture(authored by Media Solutions, University of Utah)
As well, a history and format overview is available in the article RealNetworks from the Wikipedia.
Of course, RealNetworks maintains its own website related to all things about Real.
[edit] Guidelines
On a general, industry-wide level, Akamai has generated a whitepaper technical guide to "Best Practices in Digital Media Delivery" http://www.akamai.com/html/perspectives/whitepapers_content.html. No endorsements of Akamai products and services are to be inferred; however, the guide summarizes nicely the major media architectures and includes references to additional resources.
