Marratech 5.x introduces the ability
share a live application and handover control to one of them.
The application sharing function enables you to show applications
in real time to all the other
participants. Application Sharing is very useful
for on the fly updates of external documents or for online
training.
Application Sharing can be done fromWindows, Mac and
Linux. The Application
Sharing tool streams the chosen desktop
area to the other
participants' Whiteboards.

Before starting, start the application you wish to show and
place it on your desktop.
|
Then, in the whiteboard, turn on the Lead Page
Changes function. This will lead the other
participants to the application sharing page you
are about to create.
|
 |
|
|
After pressing the Application Sharing
button, the sharing mode will appear onscreen. It removes
the large video window and replaces it with an overview
of what you are sharing. The whiteboard will also be
hidden.
|
 |
This will make it easier to select the
application you would like to present to the others. There
is a small miniature Whiteboard in the sharing tool
that will show you what the others are seeing.
|

Using Application
Sharing. The area under the Shared Desktop rectangle
is being sent to the other participants.
|
|
Move the Shared Desktop rectangle over
the application you want to share.
|
 |
|
|
|
Press Play to start sharing the area under the Shared
Desktop rectangle.
 |
The Play button will start sending
the Shared Desktop rectangles contents.
The Stop button will stop sending the Shared
Desktop rectangles contents.
The Eject button will halt application sharing
and return you to the full Marratech interface. |
You
can resize the Shared Desktop rectangle to match your
needs.
|
 |
|
|
To give control of your Shared Desktop are
to another participant, select him or her from the Allow
Control list.
ONLY GIVE CONTROL TO SOMEONE YOU TRUST! Allowing someone
to control your computer has serious implications. Never
leave your computer unattended when allowing control. |
 |
| The participant you have given control to
will now be able to click the steering wheel icon in
the Whiteboard's button bar and take control of the Shared
Desktop area. |
|
| Switch back to "<Nobody>",
Stop or Eject to
stop the application sharing's remote control feature. |
|
Marratech
builds upon VNC to make application sharing possible.
This has interesting benefits, such as the ability
to use an external VNC server instead of your local
computer.
It makes it possible to hold software training on
a another computer than your own. This is possible
by opening the Options menu
item under Tools and selecting
the VNC tab. Simply specify
an external VNC server and port. |

Special considerations
Application Sharing requires bandwidth. If you
are using it frequently, be sure to use an e-meeting room
in which the Whiteboard media is configured for higher
bandwidth limits. Using Application Sharing
on an Internet connection with low upload speed will of course
lead to worsened quality in the audio and video.
Application Sharing requires more resources.
You may notice that it uses more processor power than the
traditional screen capture in Marratech.

If you feel your system is too slow when sharing an application,
try not sending video at the same time. This will reduce your
processor load.
You may bring up the whiteboard and use it to annotate over
the application being presented. This is a very good way of
writing notes or bringing attention to special details or
dialog boxes.
Sharing a large area will be slower than a small area. Try
to limit and optimize what you want to show so that the
updates will be faster.
To
share your desktop area with better color quality, open
the Options menu
item under Tools and select the VNC tab.
Change the Depth to 16. This will require more bandwidth.
