Video Layout Scaling - Cisco TelePresence System Codec C40 Administrator's Manual

Cisco TelePresence System Codec C40/C60 and Profiles using C40/60
Contents
Video Input DVI [3]/[2,3] RGBQuantizationRange
NOTE: Codec C40 has one DVI input (DVI-I 3). Codec C60 has two DVI inputs (DVI-I 2 and 3).
All devices with DVI inputs should follow the rules for RGB video quantization range defined in
CEA-861. Unfortunately some devices do not follow the standard and this configuration may be
used to override the settings to get a perfect image with any source. The default value is set to
Full because most DVI sources expects full quantization range.
Requires user role: ADMIN
Value space: <Auto/Full/Limited>
Auto: RGB quantization range is automatically selected based on video format according to
CEA-861-E. CE video formats will use limited quantization range levels. IT video formats will
use full quantization range levels.
Full: Full quantization range. The R, G, B quantization range includes all code values (0 -
255). This is defined in CEA-861-E.
Limited: Limited Quantization Range. R, G, B quantization range that excludes some code
values at the extremes (16 - 235). This is defined in CEA-861-E.
Video Input 1 DVI 3 RGBQuantizationRange: Full

Video Input DVI [3]/[2,3] Type
NOTE: Codec C40 has one DVI input (DVI-I 3). Codec C60 has two DVI inputs (DVI-I 2 and 3).
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.
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: <Off/On>
Off: No adjustment of the aspect ratio.
On: Let the system automatically adjust aspect ratio.
Video Layout Scaling: On
