Anybody with a computer using standards based video conferencing platform can do a presentation or lecture. The key is enough bandwidth and using the ITU, (International Telecommunications Union), video conferencing standards. Today, most video conferencing systems accommodate computer input. You simply plug a computer into the VGA or DVI connection on the video conferencing CODEC or system, just like plugging a computer into a LCD projector. Press the presentation button on the video conferencing remote and you are presenting anything from your computer. Most current systems accommodate the H.239 standard called “duo video.” This sends two simultaneous video streams to the other side. This means the participants see both the presenter and the computer application at the same time. There is one caveat with this standard – If the participants are using an older video conferencing system they may not have the H.239 standard in the CODEC. This means no presentation is seen at the other end.
There is always a way to work around everything in the video conferencing world. If you are presenting to those on older video conferencing CODECS or systems who do not have the duo video or H.239 standard, simply press input on the video conferencing remote and choose VGA input. Remote participants will see the presentation, although they won’t see the presenter –– They will certainly hear the presenter. Make sure you know if those at the other end have the latest video conferencing technology before you present. If you don’t the safe bet would be to simply choose VGA input on the video conferencing remote.
There are two considerations in doing a presentation or lecture through videoconferencing technology. First, how are the participants going to see and hear the lecture? Second, are you presenting to a few participants or many participants. If there are few and they have access to standards based video conferencing you are good to go. If there are many you might consider using a video conferencing bridging service with streaming capability. The streaming solution will limit input from participants; however this can be most economical and a great way to present. Whether you have a few participants or many with no video conferencing equipment you might consider using a video conferencing service offering a free standards based video conferencing application on any device such as an: iPad; iPhone; PC: MAC; or Driod. This makes presenting seamless and very easy for participants. The other benefit is the duo video or H.239 standard is imbedded through the service and participants have the benefit of seeing both the presentation and the presenter simultaneously.
