Introduction
The following are instructions for seting up a video
conference with me. For experienced video conferencing users,
I use Microsoft Netmeeting H.323 video standard, and I do not have an
IP address dedicated for video conferencing thus either I will have to
call you, assuming you have a dedicated IP address, or we can exchange
E-mail just prior to connecting.
If this makes little sense to you please read the instructions below
as to how to get your PC setup for video conferencing, or at the minimum
audio conferencing over the Internet.
Step #1 - Overview of Technology
There are two reasons video conferencing hasn't become main stream yet and
it is important to understand why. First is a lack of standards, thus unlike
going to any store and purchasing a telphone of any brand and having it work
with all other phones in the world, currently this is not the situation
with video
conferencing today. Thus, you will need to use software which meets the
same video conferencing standards as the person on the other end of the
connection. The software I use is
Microsoft Netmeeting
which conforms to H.323 based video conferencing standards
for Win95/98 and WinNT users, and fully supports the T.120
standard.
Netmeeting does not currently support the H.320 standard.
Thus, be sure to check with your products documentation as to whether it
supports communicating with a Netmeeting user. Second limited factor
with video conferencing is the lack of high speed Internet connections.
Unless you have at least a 28.8 modem connection there really isn't much
sense giving this a try, though acceptable voice can be heard at
Internet connections as low as 14.4 modem connections.
Step #2 - Hardware Required
You really should be running at least a Pentium class computer. Assuming
you plan on running Netmeeting you will need at least a sound card and
microphone to communicate with me. You also should make sure that your
sound card supports full duplex audio so that both parties can simultaneously
talk. Most boards including the popular
Sound Blaster
series have this
support today for the Windows operating systems. However, if you haven't
updated the audio software drivers
on your PC recently you will most likly require a visit to your sound cards
web site to download the updates. Products like Microsoft's Win95 and
WinNT CD's were published prior to the release of many full duplex
drivers thus you can't rely on using the drivers that came with your
operating system. Now if you want to actually give me the ability to see
you through a camera you will also need a video capture card and camera
which support Microsoft Netmeeting. One word of warning if you plan on
purchasing something like this. The cheaper camera's which plug into your
Parallel port like the popular
Connectix QuickCam
provide far less quality as compared
to a dedicated hardware card which you can plug in either a proprietary
camera or even a standard CamCorder. I myself am using the
WinNov
card which I can highly recommend with a CamCorder attached. Though if
you just want to have some fun and give video conferncing a try, there is
nothing wrong with buying a camera which attaches to your parallel port,
but be warned that without a dedicated hardware board in your computer to
handle the video processing the quality will not be as good.
Step #3 - Software Required
Best thing about Microsoft Netmeeting is that it's free. Free is the
sense that you have already spend $100 on a Microsoft operating system. The
Netmeeting product is included in the Microsoft Internet Explorer 4.0 as long
as you choose the FULL INSTALLATION when installing it on your system. It
can also be downloaded from Microsoft as a separate product if you happen
to be using a non-Microsoft browser
(i.e. Netscape). Conferencing
software within Netscape, though very good, does not currently include
video conferencing support. Inaddition it does not support the same standards
as Microsoft for audio conferencing thus if your goal is to communicate
with me please let me know you will be using Netscape so I can run the
same software on my end of the connection.
Step #4 - IP Addresses
As briefly mentioned above the way we find each other on the Internet is
by calling the IP address the other person is logged into. An IP (Internet
Protocol) address is a series of 4 numbers separated by decimal points.
For example the Netmation IP address is 204.122.26.140, however this is not
the IP address I use when logged in for video conferencing. To make
matters a bit more confusing depending on how you are connecting to the
Internet there are Internet connections referred to as Dedicated IP and
Dynamic IP. If you
have a Dedicated IP connection your IP address will always be the same
everytime you log on to the Internet. However, if your service provider is
assigning you a random IP address each time you log on, this is called a
Dynamic IP address assignment and is why we would need to communicate with E-mail
prior to finding each other on the Internet to start a video conferncing session.
How do
you find the IP address you currently have. If your using Win95, press the
START button and enter WINIPCFG.EXE, in WinNT go to a DOS prompt and
enter IPCONFIG.EXE. You also can get this information in WinNT graphical
mode by following this sequence: Dial Up Networking Icon / More Button /
Monitor Status on Pull Down Menu / Status Tab / Details Button.
And who says Microsoft doesn't make easy to
use software? This will show you the series of 4 numbers called
an IP address. Also please provide your email address at the Internet
provider you are logged into which can also be used to create a connection.
Also as a final note if you a host of security which your Internet connection
goes through such as firewalls there may be problems using Netmeeting through
those types of security.
Step #5 - Conferencing Tips
As mentioned the Internet connection speed is a big problem currently for
this type of application. Thus, be sure to use a small video picture if
you are transmitting video. In the coming years higher speed connections will
start becoming more popular such as
Cable Modems
and the phone companies
DSL
services. Until then you can at least get an introduction to video
conferencing by trying it today. Just don't expect too much!
