Contents Introduction
Video Input Source [1..5] OptimalDefinition Threshold60fps
For each video input, this setting tells the system the lowest resolution where it should transmit
60fps. So for all resolutions lower than this, the maximum transmitted framerate would be 30fps,
while above this resolution 60fps would also be possible, if the available bandwidth is adequate.
Requires user role: ADMIN
Value space: <512_288/768_448/1024_576/1280_720/Never>
512_288: Set the threshold to 512x288.
768_448: Set the threshold to 768x448.
1024_576: Set the threshold to 1024x576.
1280_720: Set the threshold to 1280x720.
Never: Do not set a threshold for transmitting 60fps.
Example: Video Input Source 1 OptimalDefinition Threshold60fps: 1280_720
Video Input Source [1..5] Quality
When encoding and transmitting video there will be a tradeoff between high resolution and high
framerate. For some video sources it is more important to transmit high framerate than high
resolution and vice versa. The Quality setting specifies whether to give priority to high frame rate
or to high resolution for a given source.
Requires user role: ADMIN
Value space: <Motion/Sharpness>
Motion: Gives the highest possible framerate. Used when there is a need for higher frame
rates, typically when a large number of participants are present or when there is a lot of
motion in the picture.
Sharpness: Gives the highest possible resolution. Used when you want the highest quality of
detailed images and graphics.
Example: Video Input Source 1 Quality: Motion
Video DefaultPresentationSource
Define which video input source shall be used as the default presentation source (when you
press the Presentation key on the remote control). The input source is configured to a video input
connector. See the Video Input Matrix table at the back of the codec and the description of the
Video Input Matrix in the Interfaces section.
Requires user role: USER
Value space: <1..5>
Range: Select the video source to be used as the presentation source.
Example: Video DefaultPresentationSource: 3

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>
Example: Video Input DVI 3 Type: AutoDetect
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.
Requires user role: ADMIN
Value space: <On/Off>
Example: Video Layout Scaling: On

Password protection
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.
On: Let the system automatically adjust aspect ratio.
Off: No adjustment of the aspect ratio.
