Real Time Streaming

Unlike progressive streaming, real-time streaming requires a special streaming server. This can be a QuickTime Streaming Server (RTSP), a Real Networks Server or a Windows Media Server. Video streamed for real-time plays automatically. You don't need to download the entire video before playing. You can jump to any location in the video clip. And the clip always resides on the server. Video encoded for real-time streaming generally tries to keep pace with the user's connection speed in order to minimize interruptions and stalling. There's nothing you can do about general Net congestion, but the streaming server at least tries to compensate by maintaining a constant connection.
