Release: Tuesday, March 31, 2009 Abstract A streaming media system is a system designed to distribute digital media content from an encoder or a capture application to a media server, and finally, to a media player for rendering or playback of that content. The Media Streaming Server System protocols are a series of protocols designed to achieve that task. This document serves as a companion document to the protocol and data structure specifications included in the Media Streaming Server System protocol documentation set. It provides an overview of the Windows Media protocols that are implemented in the Windows Server operating systems and that are used to interoperate or communicate with Windows client operating systems. This document describes the intended functionality of the Media Streaming Server System and how it interacts with systems or applications that need to stream media. As mentioned, the Media Streaming Server System supports multiple protocols for streaming digital media to and from a media server. This document identifies those supported protocols and how they interact in a combined system.
