Dual Video Stream ( DuoVideo, H.239, BFCP ) - With Dual Video Stream you have the opportunity to show two different live video streams simultaneously, main video and one additional source. This is handy when showing a presentation. You see the live presentation and the live video of the presenter simultaneously. When you start a presentation, Dual Video Stream starts automatically if both local and remote system supports Dual Video Stream. If one of the systems does not support Dual Video Stream, no second video stream will be established and your presentation will be shown as your main video.
Dual Video Stream is available on all systems with Natural Presenter Package installed.
In Presentation Settings, you can set Presentation Start to Manual. That means that Dual Video Stream will not start automatically.
Dual Video Stream and Bandwidth - Using Dual Video Stream, the quality automatically downspeeds to the optimal bandwidth. This means that you need higher quality to allocate enough bandwidth for the two video streams. Dual Video Stream borrows bandwidth from main video stream. When Dual Video Stream is closed, the bandwidth is returned to the main video.
