[AG-TECH] Questions about remote presentation technology software

[Jason Bell]

G'day John

We here at CQU use a number of different methods for "Sharing" a
presentation.

*	Using VNC, works well, but due to firewalls external
participants are unable to view the presentation.  (You might want to
try VenueVNC) Poor frame rates, ie cannot stream mpegs, etc.

*	Using Shared Presentation, works well, but again you are relying
on the Venue Server to be up, etc.

*	Using Shared Desktop (see agcentral.org), as this share
applications appears to work well, but again the firewall issues pops up
again. Poor frame rates, ie cannot stream mpegs, etc.

*	Using the TV output of the computer, I stream the desktop as a
"vic" stream.  Works well, but quality is poor due to codec being used.
No need to worry about firewalls and has good frame rates and can stream
multimedia files well.

I regularly the above methods myself, and each have their own niche
markets...

If you have any questions, please don't hesitate to contact me.

Cheers,
Jason.

Hello AG Tech,

What technology do you prefer to display a presentation over the Access
Grid?

For instance, do you use VNC external to the venue client by installing
a
VNC server for others to view from a VNC client or do you choose to
upload a
presentation to the venue client?

What other methods do you use to display a presentation over the Access
Grid
and why?

As I am experiencing VNC client drop off from the external VNC server we
use, I would like to consider other options.  The VNC server has its
firewall turned off during presentations.

Thank you,

John
