Videoconferencing at UVa

Using VCON MeetingPoint Software

This page contains instructions for the basic use of VCON MeetingPoint videoconferencing software. A full manual is provided by VCON.

These instructions are written using version 4.6. Although other versions may look different, the functions are basically the same.

  1. Start VCON MeetingPoint. A Conference Panel is displayed at the top of the screen and a window is opened which shows the local video image and a toolbar underneath.

    You should see your local camera image in the window. If you do not, check that the power to the camera is on and that the cable that carries the signal is connected at the camera and at the VCON board. Also be sure that the correct camera source is chosen -- there are two inputs on the VCON board. Choose between them with the icon on the Local Video window. Camera 1 selects the s-video input; camera 2 selects the composite input.
  2. There is no mechanism for testing the audio signal without being in a call, but there is an icon on the Local Video toolbar that allows you to select between Private (the phone-type handset) and Speaker (external microphone and speakers).

  3. The videoconference profession uses the same terms as the telephone profession. Thus a "call" is "dialed". You can either select the LAN Dialer option from the Dialer pull-down menu on the Conference Panel, or select the telephone icon on the Local Video toolbar.

  4. The menu route will open a Dialer window with the LAN option visible. The telephone icon will open the Dialer window with whichever option was chosen last. In most cases, this will be the LAN dialer. If you don't see the LAN dialer, select it under Manual Dialers.

  5. The bandwidth option is very important since it controls the number of frames and video quality. Sometimes you will need a specific bandwidth to match equipment at the far end of the connection. To set this option, select Options (see below) on the Dialer window. This will cause the Dialer window to expand to show the options on the right-hand side. Unfortunately, there is a bug which prevents the window size from showing the entire window, and the window does not allow itself to be resized. Chances are you don't want the keypad, but if you do, there is a kludge.
    Put the cursor over the dividing line between the dialer list and the center panel. Pull the divider to the left. This will pull both the central panel and the keypad into the window.
    The bandwidth setting is shown in a pull-down menu near the bottom of the center panel. If the displayed value is not the one you want, choose a different value from the pull-down menu. The values 384 and 768 are common; 320 is often used when the remote equipment is on an ISDN network with a gateway (translator) to allow communication.

    The top central field is where the dialing string should be typed. Often this is an IP address for another H.323 client. After typing the dial string, select Dial. A window with the ring status will be shown until the call is accepted at the other end of the connection.

    There is a configuration setting to be aware of here.
  6. When the call is accepted, a window is displayed which shows the Remote Video. At this point, the two parties can communicate with audio and video.

  7. If any of the T.120 (data) functions are to be used, each can be selected from the pull-down Data menu on the Conference Panel.

  8. To terminate the connection, select the Hang up icon (a telephone, again) on the Remote Video toolbar.

  9. To exit MeetingPoint, click the Globe icon on the Conference Panel, and select Exit. Note that the PC does not like to be shut down until MeetingPoint is exited.
