What
are the Technology Requirements for receiving a Webcast?
NACADA
uses the Wimba platform, provided by Kansas
State University / Axio Learning, to host our online broadcasts.
Wimba allows our presenters to share their presentations with
our viewers in a live format. You will watch and listen to
both sound and visual images that will be sent over the Internet.
NOTE: Visual images will NOT include streaming
video (sometimes referred to as "talking heads"), which requires
more bandwidth than is currently available on many campuses,
unless specifically so noted in the event description.
Our
Webcasts are designed to be viewed on any recent model Microsoft
Windows or Macintosh based computer with an adequate Internet
connection.
MINIMUM
requirements are:
- ALL:
- Sound
card and speakers that are appropriate to your reception
set-up (if you are going to broadcast to a group in
a conference room setting, laptop speakers will probably
not provide adequate projection)
- 512MB
RAM
- keyboard/touchpad
and mouse (necessary for interaction with the presenter)
- Screen-saver
must be turned off
-
PC
System Requirements
- Desktop with 2.0 GHz Pentium
4 processor or Laptop with 1.4 GHz Centrino processor
Windows XP Professional operating system
- NOTE:
Windows Vista users
should note that problems have been experienced with
the security settings within Vista, preventing registrants
from participating in our webcasts. Participants using
Vista must plan for and complete the Wimba Wizard pre-event
checks well in advance of the scheduled webcast in order
to allow your local technical support team time to troubleshoot
and resolve any issues.
- Macintosh System
Requirements
- Desktop or Laptop with 800 MHz
processor
- Macintosh OS X operating system
- What
you will NOT need:
- a
microphone - audio communication will be one-way from
the presenters to you
- a telephone - audio is
presented via the Internet (VoIP)
- Supported Web Browsers
- Internet Explorer version
7.0 or above
- Mozilla Foxfire version 2.0
or above (usuable for PC/Mac, but some problems have
been encountered with pop-up windows even after blockers
have been turned off, therefore we do not recommend
using this browser for Webinars)
- Safari (recommended for Mac)
(Axio
Learning technologists recommend that you keep your computer
up-to-date with the latest versions of these browsers. Find
links to downloads at http://public.online.ksu.edu/support/downloads.php.)
- Browser
Configuration
-
ALL pop-up
blockers must be disabled (including
Google toolbar) or have http://129.130.12.226 added
to the blocker's whitelist (list of accepted addresses).
- Your
system must be Java
and JavaScript
(Cookies) enabled -- with only the most recent version
of JAVA.
- Make
certain that all previous versions have been uninstalled. **Conflicts
caused by older versions of JAVA, or having multiple
versions of JAVA installed, are among the most common
causes of problems with broadcast reception. (Find
links to download the latest version of Java at
http://public.online.ksu.edu/support/downloads.php.
-
Internet access
-
at 56k or above - Broadband
strongly recommended. (NOTE: Internet
connectivity issues are the most common problem
encountered by participants. We have monitored
our previous webinars and found that the out-going
signal is relatively small, usually only about 13
kilobits per second. However, bottlenecks
can occur anywhere between our servers and your
computer and occasional dropouts of the signal are
frequently the results of these conditions and not
a problem with the signal leaving our campus. If
bandwidth on your campus is not
sufficient to handle the broadcast in addition to
all the other Internet interactions taking place
there at the given time, the audio and visual portions
of the event may not play "in sync" or may even
not be receivable. Since this is strictly a campus
or intermediary issue, the K-State IT HelpDesk will
not be able to assist you with connectivity problems. "State
of the art" computer equipment will not ensure good
reception if bandwidth is not sufficient!)
- Port Requirements
- Generally, the port
requirements necessary for entering the Wimba room are
the same as those needed to access web pages: Standard
Web Access (Port 80/tcp). Our webinar room can be accessed
through a direct connection or web proxy, through Port
80/tcp. Components (features) of Wimba will upgrade
to use more efficient transport methods, when possible.
In these instances, the user will seamlessly upgrade
by trying multiple alternate/raw ports for connectivity.
- For TCP, and alternate
HTTP: 5998, 443 and port 5190.
- For UDP: port 5998, 33434,
5190, and 16384.
- Institutional requirements
- Your Institution's firewall
set-up must allow internet broadcast reception.
If you are behind a firewall, there is a chance that
you will not be able to receive the broadcast, even
if you ARE able to enter the presentation room. PLEASE
check with your institution's IT support staff well
before the event to determine if this may be
an issue for you. (The K-State IT HelpDesk will not
be able to assist you with firewall blockage.)
If you have any additional questions about
Technology Requirements, please call the K-State IT
Helpdesk at 785-532-7722 or 800-865-6143. Please
tell the technologist that your question relates to viewing
a NACADA webcast
on the Wimba platform.
