Day 17: Sharing Your Computer Screen: Potential Challenges

If you’re new to videoconference projects, you’re bound to run into a problem seeing or sharing a computer screen sometime soon. Here’s the situation and what to do about it.

H.239 / Duo Video / People Plus Content

Many of the manufacturers offer a feature that allows you to share your computer and your faces at the same time. This feature is great when you’re connecting to people on your network. It’s ideal for full length shared courses; making direct instruction better.

However, when you want to use this feature with another class from somewhere “out there” off your network, it’s a different story. There are several scenarios where it won’t work:

  • If the other school’s equipment doesn’t support H.239 (a lot of old units out there still)
  • If the other school’s equipment has the H.239 featured turned off
  • If the other school’s firewall blocks H.239
  • If the other school connects through a bridge and the bridge has it turned off
  • The bridge you connect through and the bridge your partner class connects through can’t pass H.239 between each other

So now, you realize that the chances of it working in a collaboration with a school off your network is really high! And now you know what can cause it.

What to Do

Either you will be the one trying to share the computer; or your partner class might try to share the computer… and poof, it doesn’t work. What do you do?

Forget the wires! My favorite solution is just that. Don’t connect it.

ZOOM!!! You can just set the laptop on a table; zoom the camera in; set a preset.

Voila!

By the way, this solution is at least 4 years old and not my original idea. Complements of Joan Roehre, Kenosha, WI.
