Stored audio/video can reside either on a Web server that delivers the audio/video to the client over HTTP, or on an audio/video streaming server that delivers the audio/video over non-HTTP protocols.
 
A direct socket connections is made between the server process and the media player process.  This is typically done by making use of a meta file, a file that provides information about the audio/video file that is to be streamed.
