xConfiguration Video Input DVI [3, 5] Type

The official DVI standard supports both digital and analog signals. In most cases the default
AutoDetect setting can detect whether the signal is analog RGB or digital. However, in some rare
cases when DVI-I cables are used (these cables can carry both the analog and digital signals) the
auto detection fails. This setting makes it possible to override the AutoDetect and select the correct
DVI video input. This setting should also be used if the video input is an analog component (YPbPr)
type signal. This is used by some cameras (Sony EVI-HD1) and DVD/Blu-ray players. Since it is not
possible to auto detect the difference between AnalogRGB and AnalogYPbPr, the AnalogYPbPr
setting must be selected.
Requires user role: ADMIN
Value space: <AutoDetect/Digital/AnalogRGB/AnalogYPbPr>
AutoDetect: Set to AutoDetect to automatically detect if the signal is analog RGB or digital.
Digital: Set to Digital to force the DVI video input to Digital when using DVI-I cables with both
analog and digital pins and AutoDetect fails.
AnalogRGB: Set to AnalogRGB to force the DVI video input to AnalogRGB when using DVI-I cables
with both analog and digital pins and AutoDetect fails.
AnalogYPbPr: Set to AnalogYPbPr to force the DVI video input to AnalogYPbPr, as the component
(YPbPr) signal cannot be auto detected.

xConfiguration Video Layout Scaling

Define how the system shall adjust the aspect ratio for images or frames when there is a difference
between the image and the frame it is to be placed in.
ADMIN
Requires user role:
<On/Off>
Value space:
On: Let the system automatically adjust aspect ratio.
Off: No adjustment of the aspect ratio.
xConfiguration Video Layout Scaling: On

xCommand
Define what to do if the aspect ratio of a video input source doesn't match the aspect ratio of the
corresponding image frame in a composition. For example if you have a 4:3 input source (like XGA) to
be displayed on a 16:9 output (like HD720).
Requires user role: ADMIN
Value space: <Manual/MaintainAspectRatio/StretchToFit>
Manual: If the difference in aspect ratio between the video input source and the target image
frame is less than the ScaleToFrameThreshold configuration (in percent), the image is stretched to
fit. If not, the system will maintain the original aspect ratio.
MaintainAspectRatio: Will maintain the aspect ratio of the input source, and fill in black in the rest
of the frame (letter boxing or pillar boxing).
StretchToFit: Will stretch (horizontally or vertically) the input source to fit into the image frame.
NOTE: The general limitation is that you cannot upscale in one direction and at the same time
downscale in the other direction. In such situations the codec will apply letterboxing.
Example: xConfiguration Video Layout ScaleToFrame: MaintainAspectRatio
Only applicable if the ScaleToFrame configuration is set to manual. If the difference in aspect ratio
between the video input source and the target image frame is less than the ScaleToFrameThreshold
configuration (in percent), the image is stretched to fit. If not, the system will maintain the original
aspect ratio.
Requires user role: ADMIN
Value space: <0..100>
Range: Select a value from 0 to 100 percent.
xConfiguration Video Layout ScaleToFrameThreshold: 5
Example:
Select where the small selfview PiP (Picture-in-Picture) will appear on screen.
Requires user role: ADMIN
<UpperLeft/UpperRight/LowerLeft/LowerRight/CenterRight>
Value space:
UpperLeft: The selfview PiP will appear in the upper left corner of the screen.
UpperRight: The selfview PiP will appear in the upper right corner of the screen.
LowerLeft: The selfview PiP will appear in the lower left corner of the screen.
LowerRight: The selfview PiP will appear in the lower right corner of the screen.
CenterRight: The selfview PiP will appear in to the right side of the screen, in center.
Example: xConfiguration Video SelfviewPosition: LowerRight
