Multimedia On The Web:
It's all about the Plug-ins
By John Anderson
June, 2000
You've probably have visited a website that has offered to inform or
entertain but have been greeted with a "Plug-in Required"
warning. While most website restrict them selves to words and pictures,
many sites make full use your computer’s Multimedia capability.
Multimedia on the Web can involve listening to audio, watching animations
and videos and retrieving information. These sites use sound and movement
for training, entertaining and making their information come alive.
To experience multimedia online, you will need to have a computer with
a sound and video card. Then what you need are special pieces of software
called plug-ins. Plug-ins are software programs that extend the
capabilities of your web browser in a specific way - giving you, for
example, the ability to play audio samples or view video movies from
within your web browser.
The number of file types on the Internet is enormous and growing. No
one program can possibly interpret them all. This is why there is a myriad
of helpers and plug-ins.
First, we should explain a couple of terms.
A helper is a program that works beside a large program such as your
web browser to do some job that it either cannot do, or cannot do as well
as the helper. For example a very useful helper program is GetRight
(www.getright.com). It is a program
to help you download files from the Internet. It allows you to easily
download files and resume downloading from where you left off if errors
occur.
A plug-in is a program that can seamlessly handle some file type from
within your browser. Ideally, a plug-in adds features to a main program in
such a way that the new capabilities seem to be part of the original
program. An example of this is the ViewMovie plug-in, which integrates
QuickTime sound and video into several leading Web browsers.
For Netscape Navigator Users
Navigator plug-ins need to be downloaded and installed. If you go to a
web page that contains a file requiring a plug-in that you don't have, you
will usually receive a message asking if you want to get the plug-in.
First, you should have a directory or folder on your computer for
downloading files over the net and put new folders inside it. We suggest
using the C:\Temp directory. Next close all running applications on your
computer. Finally, Double-click on the file to begin installation.
Some but not all Plug-in require you to restart you computer after you
complete installation. After you restart you will be able to start using
the features of your new plug-in.
For Microsoft Explorer Users
Microsoft designed Internet Explorer to be able to automatically
install ActiveX control plug-ins.
Shockwave is a good example of this. All you need to do is go to the
Macromedia site with Explorer and click on the link to install the ActiveX
control. The rest happens automatically. The next time you go to a
"Shocked" website, the Shockwave control loads and plays the
interactive movie.
Get Plugged-in Now
Many plug-ins and controls can be downloaded for free over the
Internet. To get you started, here are a few of the more popular ones:
Currently the MSBA website has only a few pages that require a plug-in.
Acrobat Reader is used to read PDF documents that can be found on our
website
HTML, the code used to create web pages, cannot maintain all of the
formatting and presentation for many documents. In such cases, PDF
documents are used to maintain the look and presentation of the original
document using a free reader available from Adobe. (www.adobe.com/products/acrobat/readermain.html)
PDF is an acronym that stands for Portable Document Format.
The PDF file format was created by Adobe and lets you view and print a
file exactly as the author designed it, without needing to have the same
application or fonts used to create the file. PDF format faithfully
preserves the look and feel of the original document complete with fonts,
colors, images, and layout.
It is a cross-platform file format that displays documents independent
of the software, hardware, and the operating system used to create the
file. In simple words, you can read a PDF document in Windows 98 that was
created on a Macintosh that you downloaded from a Web site running UNIX.
Get
animated and interactive with Shockwave (www.shockwave.com),
one of the most useful plug-ins on the Net. At the Macromedia (www.macromedia.com)
website you'll find lots of exciting "shocked" sites to see.
Flash (www.macromedia.com/software/flash/)
is another popular plug-in from Macromedia. It turns your computer into an
interactive animation machine.
Turn
your computer into a radio or television with the Real Player (www.realplayer.com).
You should have a 28.8 modem or better. Once you install the RealPlayer,
you can listen to the latest newscast from National Public Radio (www.npr.org),
CNN (www.cnn.com), and hundreds of
other sites.
VDO
Live (www.vdo.net) delivers audio and
video in real time. With a 28.8 modem you will get a small video picture
that runs at 10 to 15 frames per second. By comparison, the video on your
TV set runs at 30 frames per second.
 From
Apple Computer comes QuickTime (www.apple.com/quicktime/),
a plug-in for playing video clips. You can watch movie trailers and other
multimedia with this useful little program.
Just in case these aren't enough, you can find an exhaustive list of
Navigator plug-ins and ActiveX controls at Browser Watch (browserwatch.iworld.com).
Check out either ActiveX Arena or Plug-in Plaza. You'll be amazed at the
variety of these add-ons you'll find.
