3Copy the SDP ﬁle to your streaming server computer.

In most cases you should not modify the SDP ﬁle manually. However, if you change anything about the media you’re streaming, you must delete the SDP ﬁle, let the broadcast software create a new SDP ﬁle, and then copy this new SDP ﬁle to the media directory on your streaming server.

For more information on SDP ﬁles, search the web for RFC SDP or RFC RTSP.

Streaming Live Media

Live media requires minimal preparation as long as you have the correct equipment.

To stream live media:

1Connect the audio or video equipment to the computer you’re using to capture and encode the live signal.

2Set up your broadcast software following the instructions that came with it.

If you’re using QuickTime Broadcaster and the Automatic Unicast (Announce) transmission method, the broadcast software creates a Session Description Protocol (SDP) ﬁle automatically, if needed. For more information, see “Using Automatic Unicast (Announce) With QTSS or DSS on a Separate Computer” on page 43.

If your broadcast software does not have this feature, you must create an SDP ﬁle on the computer you use to capture and encode the live signal. See the instructions that came with your broadcast software.

3Copy the SDP ﬁle to your streaming server computer.

Be sure to copy the ﬁle into the media directory you’re using for streaming.

4Make sure the streaming server is running.

5Start the broadcast software following the instructions that came with it.

6Test the broadcast by connecting to your streaming server with client software.

Give users an RTSP URL to your SDP ﬁle, or an HTTP URL to the QuickTime reference movie that you placed on your web server. If you want the streamed media to show on a web page, set up the web page by using the EMBED tag or creating a separate QuickTime reference movie (for more information about setting up a web page, see “Setting Up a Web Page With Streamed Media” on page 32.

Viewing Streamed Media From a Client Computer

To view streaming media, users must have QuickTime 4 or later installed.

To view media from a client computer:

1Open QuickTime Player.

2Choose Open URL from the File menu.
