Using QuickTime Streaming Files




More and more class-related media files are being made available through WebCT and the LTS Quicktime Streaming Server. Some of the most popular are audio files that accompany foreign language text books. All public computers at Brandeis are configured with Quicktime, so you will always be able to view your files.

Do I have access to WebCT?



To have access to these files, you'll generally first need access to the WebCT course in which they are posted - this access is automatic once you're enrolled in a class that has a WebCT component. You can log in to WebCT by surfing to http://webct.brandeis.edu in Internet Explorer and entering your UNet username and password, then clicking on the appropriate course.

If you're having trouble logging in to WebCT, contact the staff at theTechnology Resource Center for assistance: call x64739 or e-mail trc@brandeis.edu.

Once you've logged into your WebCT course, you should find an icon pointing to the streaming files you need to hear (or to an index of files). Clicking on the link of the file should open a browser window with a small Quicktime Player interface, which should in turn begin buffering and then playing. If this doesn't happen, the following troubleshooting list should help you figure out the problem:

Q: Is Quicktime Player installed on my computer?



If it is not, or if you have an older version, point your browser to http://www.apple.com/quicktime/download/ to download the latest version of Quicktime Player.

Q: Is the audio turned on?



The sound may be turned off in your computer's settings, or your external speakers may be off. In Windows, double-click the speaker icon in the system tray to set the volume. On a Mac, go to the Apple menu and select Control Panel > Monitors and Sound.

Q. Have I selected the correct connection speed in Quicktime player?



Check to make sure you have set the correct connection speed for Quicktime Player. Open the Quicktime Player and click Edit > Preferences > Quicktime preferences > Connection Speed. Select the speed that matches your Internet connection.

Q. Is your Quicktime browser plug-in installed?



To view and hear Quicktime files in your browser, the Quicktime browser plug-in must be installed. You can check to see if this is the case by going to: http://www.apple.com/quicktime/download/qtcheck. If the Quicktime logo is visible at the bottom of the page, the plug-in is properly installed.

Q. Can I access ANY Quicktime movie?



Check to see that you can access any streaming movie by opening the Quicktime Player and clicking Edit > Preferences > Quicktime preferences > Streaming transport. Click the Auto Configure button. Quicktime should confirm that it can use UDP/RTSP port 554. If it switches to http:// port 80, then you are most likely behind a firewall, which likely means that a firewall is configured to block Quicktime streaming files.

Q. How do I tell my firewall to allow streaming files?



The firewall issue is a tricky one. If you have a cable/DSL modem and a router with NAT firewall:

  1. Open the Web-based interface for the router
  2. Select Advanced and choose "Port forwarding" (wording may differ for your router)
  3. Open port 554 for RTSP/TCP data
  4. Open ports 6970 through 6999 (inclusive) for RTP/UDP data.


Consult your router's documentation for specific instructions on configuring port forwarding.

Q. What do I do next?



If you've followed all the steps above and are still unable to receive Quicktime streaming files, you should contact Brandeis LTS for further assistance: call x64739 or e-mail trc@brandeis.edu.
