A broadcast stream is a stream source to be subscribed to by clients. To subscribe to a stream from your client Flash application use NetStream.play method. Broadcast stream can be saved at the server-side. @author The Red5 Project @author Luke Hubbard (luke@codegent.com) @author Steven Gong (steven.gong@gmail.com)
