Videoconferencing with Web Conferencing
There is a clever way to expand the capabilities of Web conferencing without video to add
video by using what we discussed in Chapters 6 and 7 to combine two solutions to make a
Web video conference solution.Though our ?rst recommendation would be to use one of
the solutions with integrated video, but you should know that this is another option
depending on your needs.The Web videoconference solutions with integrated video will
provide you far more control over the video and provide a better Web videoconference
experience because everyone will be able to at least see the presenter and a couple of the
participants.
You could for example use Skype, MSN Messenger, or SightSpeed to add video to a
non-video Web conference solution if all the participants were logged on to the video call

solution. For example; if you had 10 users in a Web conference, you could also have all ten
participants and the leader using MSN Messenger and when the conference leader wanted
to see a participant, he or she could initiate a video call to the active participant and they
could see one another to better interact. Of course, the other participants could only listen
in using the telephone conference portion and would not see any video image unless they
were the active talker in a video call with the presenter.They could, however, have a video
call with each other during the Web conference to discuss something to do with the Web
conference or formulate a question to ask.
Web Videoconferencing Solutions
Two solutions have fully integrated video in a Web conferencing solution and work with
both Windows and Mac.There are many Web conferencing solutions, but we will discuss
only three that have full-function Web conferencing with video capability.Adobe purchased
Macromedia in 2005 and is one of the better solutions, as is WebEx for true Web videocon-
ferencing. Both of these offer a service option so you do not need anything but a Web
browser and/or client software, and of course a webcam, to have a Web videoconference.
Everything is hosted by the service provider and so all that you need is to pay the service
costs. We also discuss two other solutions: WebDialogs Unyte, which offers a maximum of
four-person Web videoconference solution and Microsoft Live Meeting, which currently
does not offer video, but we know that it is coming. It will include the use of MSN
Messenger 8.0 as a part of Live Meeting to offer video in the future.
WiredRed e/pop Web & and Videoconferencing
WiredRed has a solution called e/pop that is a Web conference tool and has the option for
adding one-to-many video or many-to-many video.This was the best solution we tested
and we were impressed with how easy it was to control the video of the Web conference
and we had eight people on the Web videoconference call. Remember, broadband connec-
tions are far faster for download than upload and if the solution supports it, it can send as
many users as your connection can handle. e/pop can handle 12 users on the screen for a
Web videoconference depending on the size of the video window, which is completely
controllable by the presenter. Let's say you have 25 users on a Web videoconference call; the
presenter would control which participants would be viewed for all the participants on the
conference. Unless you have a small Web videoconference, you would not have or most
likely not want all those people on the screen at once due to confusion and bandwidth
consumption.
e/pop is designed mostly for the corporate environment as it is licensed software, but
they also have a few options for a hosted service so that you could use the service on a

month-by-month basis if you needed this capability. It is available in on-premise software
and fully hosted service offerings. e/pop is primarily used by business, government, and
educational networks for sales presentations, online customer meetings, training, customer
service, telecommuting work, and worldwide virtual team meetings. e/pop is also used by
service providers and other sponsors for friends and family videoconferencing such as U.S.
overseas troops, evening home video calls for traveling employees, and more.
e/pop provides traditional Web conferencing capabilities, plus fully integrated high-
quality video. Users can share PowerPoint presentations and documents completely on the
?y (no pre-processing required), whiteboards, Web browsers, applications, and their entire
desktop. e/pop is unique in its capability to seamlessly include multiparty, fully interactive
video, including videoconferencing sessions with 10 or more participants, plus the capability
to record and play back multipoint video. New users simply select Play All, and everyone
with a webcam (or video input source) is fully interactive.Advanced users can avail them-
selves of a variety of video layouts, including picture–in-picture, tiled, and ?oating.The soft-
ware automatically adjusts video size, quality, and frame rate.This makes e/pop ideal for
day-to-day meetings where users develop viewing and productive working preferences.
