4.3.1Presentation Start
If your system has Dual Stream capabilities, you can show two video streams at the same time (see also Dual Stream). Presentation Start is Auto by default. This means that you will start Dual Stream (a second video stream) automatically when starting a presentation. Dual Stream requires the Presenter Option and H.263 video. To check which options are installed, see the System Information menu in Control Panel.
Manual means that you manually choose if you want to start Duo Video or not every time you start a presentation.
Auto
Dual Stream starts automatically when you start a presentation (in other words, when you choose a second video source). If your system or the far end system is not capable of Duo Video/H.239, you will not use Dual Stream, but rather send the presentation source as your Main Video
Manual
When starting a presentation, select Presentation in the call menu and select Start Presentation. Choose a video source from the list displayed on the screen.
