Region of Interest
(ROI)
The Region of Interest parameters select a portion of the input picture that will be used for
scaling and/or positioning. The selected area can then be scaled to a standard pillarbox
or letterbox size and shape (On Square), or it can be set to a full screen input image (On
Full).
NOTE: On Full may cause image distortion if it is used to expand an odd-shaped region of
interest to full screen.
The ROI Setup mode allows you to preview the edges of your selected Region Of Interest
as you set it up. After selecting the desired region using the Setup Cursor, you can take
the region to air by setting Region Of Interest to On Square or On Full.
The Setup mode is not required to operate the ROI feature. The edges of the Region Of
Interest can also be adjusted while in On Square or On Full modes
15.0 Region of Interest This parameter turns the Region of Interest settings On or Off. When enabled, the ROI Left,
Right, Top, and Bottom controls define the rectangular shape and position of the ROI.
Interactions occur between ROI settings and other parameters:
• The Region of Interest menu is not displayed when Active Format Description (AFD) is in
control of the Conversion Mode. While downconverting, with Downconvert Mode set to
Auto AFD, any values assigned for ROI parameters are ignored.
• Custom Size and Position settings work interactively with ROI, but Custom Crop settings
are disabled. Custom Size/Pos is also temporarily disabled while in the ROI Setup mode.
15.1 ROI Left This parameter sets the left boundary of the ROI.
15.2 ROI Right This parameter sets the right boundary of the ROI.
15.3 ROI Top This parameter sets the top boundary of the ROI.
15.4 ROI Bottom This parameter sets the bottom boundary of the ROI.
Video Legalizer
These parameters allow adjustment of signal levels to meet legal broadcast
requirements.
