Gamma Correction
Gamma correction is applied to the RGB as a simple power function, and is applied to each component
independently.

Conversion and Advanced Video Processing
(XD1)
Aspect ratio conversion is an important part of video format conversion. The XD1 supports basic pre-
defined arcing controls, custom preset arcing control, code-based automatic arc control, and a highly-
configurable ARC code-based table. See General Information on ARC and AFD (on page 46) for
information about 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
FS1 and XD1 modules have different capabilities for signaling, handling, and insertion of embedded VI,
WSS, and AFD.
The FS1 modules can perform two major functions with AFD. They can replace the AFD of an incoming
stream with a different set of AFD code generated by the module. Also, FS1 modules can insert new AFD
where it currently does not exist, and output a signal that includes newly-created AFD.
