Managing Your Streaming Server 31
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:
1 Connect the audio or video equipment to the computer you’re using to capture and encode
the live signal.
2 Set 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.
3 Copy the SDP file to your streaming server computer.
Be sure to copy the file into the media directory you’re using for streaming.
4 Make sure the streaming server is running.
5 Start the broadcast software following the instructions that came with it.
6 Test 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:
1 Open QuickTime Player.
2 Choose Open URL from the File menu.
