Conversion and Advanced Video Processing
Aspect ratio conversion is an important part of video format conversion. The X100 supports
basic pre-defined arcing controls, custom preset arcing control, code-based automatic arc
control, and a highly-configurable ARC code-based table. See page 46 regarding the use of
aspect ratio conversion and AFD codes, including graphical representations of ARC and AFD
patterns.
Status
These read-only parameters report on the ARC mode, offsets, scale, left and right crop,
AFD, and VI of the conversion processing.
AFD Presence and Output
The X100 can perform the following functions with AFD:

Replace the AFD of an incoming stream with a different set of AFD code generated by
the module

Insert new AFD where it currently does not exist, and output a signal that includes
newly-created AFD

If the incoming signal contains AFD, the module can replace the existing AFD code with
updated ARC information

Create custom AFD rules for non-standard aspect ratio changes
ARC Control
Mode
Depending on the current input/output video standard setting, the X100 operates in one of
the following modes:
Up , Down , Cross , SD-ARC , and Current . The current operating
mode is shown in the ARC Mode Fb parameter in the Status me nu.
When input video standards or output video standards change, the X100 may switch to a
different conversion mode, and the required ARC setting may be different. For this reason,
the X100 options are set according to the conversion mode, and you can pre-configure the
settings for each mode. When mode switching happens, settings will always take effect
immediately.
ARC Control
You can set the output in a particular conversion mode by selecting either a standard ARC
setting, or one of your own customized preset ARC settings, with an automatic ARC that
follows the ARC code embedded in the video.
Set ARC Control > ARC Control to one of the following selections:

Anamorphic

4:3 Pillar Box
