Input Tab Screen
Click on the Input tab to view and make changes to the converter’s input region-
of-interest settings.
An input signal is required before the Input menu configuration controls are
available. When no input signal is present, the ROI unit grays out the Input menu
controls.
The Proxy Screen on the lower right shows the current region of interest setting
in green with the selection pixel size at the bottom and the input pixel size at the
top. Various controls are also available on the left.
NOTE: The adjustments made on the green proxy screens and Screen Picker are live and
can be viewed on the SDI output.
NOTE: Portions of this screen are grayed out if no input signal is present.
ROI Selection
Using this pulldown menu you can choose a selection mode:
NOTE: Mini-Config provides a Tool-tip description for each ROI Selection mode. Hover
your cursor over the mode name in the drop-down menu for a description of its
function.
• Auto - Selects the entire signal detected at the input to the ROI (default
setting). Scales the input region-of-interest as large as possible to fit into the
SDI output region while maintaining the incoming aspect ratio. Matte may
result if the input’s aspect ratio does not match the SDI out aspect ratio.
NOTE: Auto selections in the Input screen and the Output screen are linked. Selecting
Auto from one screen will also select Auto in the other screen.
• Variable - Allows user-adjustable selection of all or a portion of the input
signal. When you select Variable as the selection type, you can choose the
region-of-interest selection in three ways with no constraints:
• Use the X,Y coordinates and W,H (width, height) size fields. Within these
fields, you can enter values (if they are valid) or use your keyboard arrow
keys to increment one pixel/line at a time for fine adjustment.
