The Open Source Streaming Alliance is a network of Open Source streaming servers located on three continents (Australia, Europe, North America) that relay and exchange their streaming content through multicast channels. The OSSA has produced a license that forms the basis of the network. This is an intertwining of the idea of a traditional broadcasting licence and an Open Source licence.

The Open Source Streaming Alliance wishes to support Open Source streaming wherever possible. For this purpose they have put together information on what streaming is, what open tools are available, and how to use them, information about how to stream using propriety tools and architectures, about video and audio codecs.

The Open Source Streaming Alliance provides a comprehensive glossary of all terms used in the streaming world.

Documentation on open streaming architecture and server installation has been written during the Playing Field project to assist server administrators to set up a streaming server node. Full detail description of the Open Source platform for live Internet streaming.
