AFD
Allows assignment of AFD (Active Format Description)
codes to the SDI output video.
Note: This function only marks the SDI output with an AFD code. Actual AFD processing must be performed by a downstream
card or system that recognizes an AFD code assigned here.
• Incoming AFD Displays incoming AFD setting as follows:
• If AFD code is present, one of the 11, four-bit AFD codes is displayed (as
shown in the example to the left). Also displayed is the VANC line
number of the incoming AFD code.
• If no AFD setting is present in the video signal, No AFD Present is
displayed.
• Output Mode Drop-down selection determines action to take in presence or absence of
existing AFD code on input video.
AFD
• Output Code Drop-down list assigns desired AFD to output SDI.
• Output Line Allows selecting the line location of the AFD data within the video signal
Ancillary Data space. (Range is 9 thru 41.)
Note: • Although the output line drop-down will allow any choice within the
9 thru 41 range, the actual range is automatically clamped (limited)
to certain ranges to prevent inadvertent conflict with active picture
area depending on video format. See Ancillary Data Line Number
Locations and Ranges (p. 3-8) for more information.
• The card does not check for conflicts on a given line number.
Make certain the selected line is available and carrying no other
data.
