Using the MBone tools
For Visual Embryo we have a guide that provides a quick default setup.
Just click one of the icons on your desktop such as:
Once you have started the connections you just need to start sending audio and video as follows:
Rat - Audio Tool
In Rat, you can see a list of users connected to the session and have controls that allow you to manipulate incoming and outgoing audio. When you first start the tool, your microphone
will be muted.
If you have trouble using the audio you should make sure that other audio inputs are disabled. To do this double click the speaker icon on your task bar near the clock.
This will bring up the “Master Out”
Select “Options” and “Properties”
In Properties - switch to “Recording” and click all of the check boxes in the list below.
Choose OK and you should now be at the “Master Record” controls.
In this window – mute all inputs except “Mic”
Now to begin sending audio – In Rat, turn off the Mute button above the microphone indicator bars as seen below:
You may need to adjust the gain on the microphone to an acceptable level each time you start RAT. You may also need to adjust the volume level of incoming audio.
The options in RAT should already be set to appropriate values be default. If you experience problems with the mic not cutting on soon enough or chopping off the first part of your
words/audio, select “Options” and turn off “Suppress Silence.”
VIC (Video Conferencing Tool)
When first joining a new session you create, your Vic window may look like this:
To begin broadcasting video:
Make sure your camera is connected correctly to your capture card. If you are using the Winnov camera (the small round camera) – then it should be hooked in to the round MXC port
(to the right of the yellow composite port). You can use a different camera than this one – but you must launch “Videum Configure” (Accessible From Start -> Programs -> Winnov
Videum -> Utilities) and select the port you want while VIC is running and transmitting.
You can tell the camera is functioning and has power if the green light shows up in the front of the camera.
Click the “Menu” button
On the Dell workstations, the correct device, port, and format should be selected by default. You will need to select the frame rate and speed. An ideal connection should be about
600kbps and 15fps. When you are ready to begin transmitting – click the transmit button and hit “Dismiss”
When returning to the Vic window – you see a small version of the data being transmitted. There will be an entry here for everyone in the session, click on an entry to see a larger version
of the video.
There is also a Whiteboard (WB) tool which is pretty much self-explanatory. A good strategy with WB is for each site to pick a different color to write on the shared whiteboard.
Click here for information using the scanner with the Whiteboard utility.
This completes the “how to” for users. It may seem like a lot of steps, but in fact you will usually just need to click on the quick launch icon.
