Testing with Active Format Description (AFD) (882 only)
When transporting HDMI video images from a source to a display, different formats may
be used between the content, transmission signal, and display. To provide compatibility
between the different formats, Active Format Description (AFD) is used.
Note: This feature is not supported on the 881 generator.
AFD describes the portion of the coded video frame that is “of interest” (or “active”). The
appropriate AFD information is transmitted with the video to the HDMI display as part of
AVI InfoFrame packets. Using AFD information, the display is able to present the image
optimally.
