66 Chapter 6 Setup Example

2 In the Network pane, enter the IP address or host name of the receiving server (the

Xserve in this example), a name for the broadcast file, the user name and password for

the broadcaster user created in Step 3, and the buffer delay (or accept the default).

Note: The buffer delay sets the number of seconds QuickTime buffers the broadcast

before playback. For broadband connections, QuickTime Player 6 or later fills the buffer

more quickly than real time, providing an “Instant-On” viewing experience.

3 Click Broadcast and start QTSS (if it’s not already running) by selecting the computer in

Server Admin, clicking QuickTime Streaming, and clicking Start Service.

To find out if the live stream can be seen from a client, open QuickTime Player on one

of the client computers and do the following:

1 Choose File > Open URL in New Player.

2 Enter the Real-Time Streaming Protocol (RTSP) URL displayed in the Location section of

the QuickTime Broadcaster window (for example, rtsp://myserver.com/mystream.sdp).

Note: The URL is case-sensitive and must be entered exactly as displayed in the

QuickTime Broadcaster window.

The live stream should start playing in QuickTime Player.

Step 6: Test Your Setup

The last step is to test the setup. This should be done as realistically as possible.

• Set up your equipment just as it will be used for the live presentation—in the actual

location, if possible.

• Ask a colleague to stand in for the presenter, or better yet, have the presenter take

part in the test, making it a “dress rehearsal.”

• Check the video image and the sound.

• Check that clients both on the local network and on the Internet can tune in to the

live stream.

• Adjust the camera and microphone positions and lighting as necessary and

troubleshoot any other problems.

Creating a Webpage for Easy Access

Enabling access from a webpage eliminates students’ having to remember the RTSP

URL and names of the streaming server and SDP files.

In our example, the webpage can be added to the existing university website, but it

can reside on any web server. Students can access the live presentation (as well as the

archives) by clicking links in their browser.

For instructions on creating a webpage with links to streamed media, see “Creating

Webpages” on page 48, which is regarding QTSS Publisher and Video On Demand.
