Picture quality of the data solution box
The picture quality received by the remote party varies depending on the type
of the terminal or connecting method, or "Monitor Out (or Sub Monitor Out)"
setting on the remote site. Using the Data Solution Box on the remote site
enables receipt of a high-quality computer picture with larger number of
frames.

For a multipoint conference, when the monitor displaying video from the Data Solution
Box is connected to the VIDEO OUT1, VIDEO OUT2, or RGB OUT terminals, the
ability to broadcast at 1 Mbps changes to about 1 image per second, even for terminals
connected to the RGB OUT terminal on the Data Solution Box.
