I want to talk to you about progressive download versus streaming
versus broadcasting. In a progressive download, you have an Apache
server. The Apache server has a file.
The client requests the file. The Apache server sends the file, even if
it's incrementally, to the client machine. And that file is held in a local cache or
in your Downloads folder on your Desktop. It depends on how you as a client have accessed
that data and how it's being served by the server.
But if it's a progressive download, it's a hinted movie. There's enough
information at the front of the movie so you can start playing it but then it
continues to download as it loads more and more data into the movie file.
And then you're left with that movie file afterwards which continues to take up
space after you're done. With a streaming server, you can have the
same static file sitting on a server prepared differently for streaming and it
can be streamed to the client, a little bit at a time.
And then as the client watches the stuff, it just disappears.
It doesn't stay on the hard drive. This is similar to how Broadcaster works.
With Broadcaster though we add some elements. We have a camera attached to a
recording machine, a Mac Book, Mac Book Pro, an iMac, something like that out in the field.
It's recording the information. So you have got your movie being recorded.
It's being sent to the streaming server and then client gets it and then it disappears.
This is very similar to the way that it works with a static movie file that's
located in the streaming server except that everything is being created live as
it's happening from the camera to the recording machine and they are being
reflected off the streaming server. So now let's take a look at how to configure
some of these things.
