A third example (
) illustrates use of the OG-ROI Rotation feature to
send selected areas of a SDI signal to portrait mounted on-set monitors at full
resolution. Each monitor uses one OG-ROI converter, accomplishing the task at a
much lower cost than dedicating DVE channels for rotation and resizing.

In a parallel configuration as
below shows a basic
configuration of the OG-ROI being used to send a 3G-SDI digital video signal
from a 3G-HDMI or 3G-DVI source to allow region of interest video input to a
video switcher. You can use methods for adjusting the region of interest selection
described in the section for the
