How
to Hear the Lectures and View the Accompanying Slides
- The RealPlayer
plug-in for your particular browser can be found at www.real.com
- This plug-in
is required for the audio elements of this site.
- Each page
of this presentation has both slide and RealAudio content. We have segmented
the audio of the lecture to correspond with the appropriate slide. You
may go through each page linearly or you may use the thumbnail button
to select a page in this lecture to jump to. You might be required to
wait a bit until all of the audio content is loaded, RealAudio is more
network intensive data than images.
- The image
of the current slide, when clicked, opens a larger window. The large
window contains "Next" and "Back" buttons. To close
this window, simply click the close button on the menubar.
- Note that
some of the speakers have removed data slides from the site to preserve
their rights to publish the data. We have indicated the missing slides.

Audio
Controls
In
order to listen to a Lecture.CAST presentation you must have the most
recent version of the RealAudio player installed on your computer.
The
RealAudio player will allow you to hear CD quality audio over the internet
as long as you have at least a 14.4 Kbps modem. You can get the
RealAudio player at www.real.com.
There are two products available, RealPlayer and
RealPlayer Plus, look for the free RealPlayer.
The
RealPlayer Plus offers additional features but it is not free.
There
are very detailed instructions on the RealPlayer site that will lead you
through the installation of the player. At the end, there is a test
file which will play automatically for you if the player has been successfully
installed.
Once
you have installed the RealPlayer 5.0, you will see the following controls
on all Lecture.CAST presentations.
 
The
Lecture.CAST icon will link you to this page when ever you need help.
This is the Play/Pause button, use it to pause the
lecture at any time. Click it again to resume playing.
The next button is the Stop button, this will stop
the presentation and return to the beginning.
 The
next icon is the Slide Position Controller. This is used to advance
to any point in the presentation. Click and hold the slider to start
the lecture at any point. When you move this slider it is necessary
for the player to "rebuffer". This is normal, and may
take several seconds. The presentation will start to play again
as soon as it has "rebuffered".
The last icon displays the total length of the presentation
and what segment is currently playing. When the numbers on the left
are counting, you should be able to hear audio. Make sure your speakers
volume is up.

Troubleshooting
Lecture.CAST
uses cutting edge technology to bring lectures to you over the internet
using standard telephone lines. If you are having problems listening
to a lecture at any time, these tips may help you.
Known
Issues for Macs using Netscape Navigator, Version
4.05 and below...
The Lecture.CAST Presentation Module uses state
of the art programming technologies to provide the the user the most intuitive
and interactive experience possible. However, Mac users viewing
the site with Netscape Navigator, version 4.05 and below WILL experience
some problems. To resolve possible conflicts, we strongly recommend
that you download and install the most recent version of Netscape Navigator,
or Internet Explorer from these links:
What
does it mean when the player is Rebuffering?
Lecture.CAST uses streaming technology to deliver
the audio of the presentations to you as you need them. This means
that instead of sending one large audio file that would take a long time
to download, our servers send small segments of the lecture to your computer
as you need them.
When the player loses connection to the sever for a number of different
reasons, it needs to rebuffer the signal of the audio. The reason
for this rebuffering could be anything from network congestion between
you and our streaming server, to your browser doing something else, such
as downloading another file.
My
RealPlayer keeps needing to rebuffer. Why?
Depending on your connection speed to the internet,
you may experience network congestion which will force the RealPlayer
to rebuffer. If you are having this problem, we suggest that you
pause the audio when a new image is downloading, this will allow the browser
to download the image. Once the image is done, restart the audio
by pressing the play button. This will eliminate the need to rebuffer
99% of the time.
