Active Format Description
This appendix is provided for a detailed overview of using the Aspect Ratio
controls when Active Format Description (AFD) is present on the input
signal. When AFD is not present on the input signal or has been disabled
on the Aspect Ratio web page, use the Aspect Ratio controls as described in
the main body of the manual (
).
Note
The additional information comprising the 10-bit AFD word, called Bar data,
describing the unused areas of active video is currently not supported.
The active image is the portion of the video picture area that is being uti-
lized for program content. The coded frame is the video frame as coded in
a compressed bitstream for emission as shown in
. This manual
uses the term coded frame to describe the area including the active video
defined by the format standard being described by the AFD.

When the module reports the presence of an AFD coded input in the AFD
Status reporting section on the Aspect Ratio web page, the AFD Input Line,
the Input Aspect Ratio, and the binary AFD Input Code are reported (see
The presence of the resulting output signal is also reported as well as the
AFD Output line, Output Aspect Ratio, and binary AFD Output Code. The
output translation of the Input to Output code is based on the up or down
conversion and the aspect ratio settings. When a 4:3 or 16:9 input signal is
passed through the module with no up, down, or cross conversion, the
AFD Input Code will be the same as the AFD Output Code.
