Typical ROI Configurations
This section covers six example configurations of ROI, including ROI-DVI, ROI-
HDMI, and ROI-SDI.
Two typical configurations for using the ROI for scaling of desktop region-of-
interest computer-sourced video are illustrated in the following two figures.
In these configurations, the pass-through monitor is used to view the subject
desktop video and to use the Mini-Config application’s Screen Picker function to
select the desired region for output to SDI (see "Screen Picker Operation" on page
21 ).
