Auto : In this mode, the AFD flags present at the input are passed unaffected. If no flag is present, the
flag specified in the default setting region is inserted.
Delete : In this mode, all the AFD flags present at the input are deleted from the video stream and no other
flags is inserted.
Default settings area
The text box is labeled according to the mode selected in the AFD Mode pulldown:
• In PASS mode, labeled DEFAULT and always empty.
• In INSERT mode, labeled FORCED, and shows the code that is forced into the system input regardless
of the actual input code.
• In AUTO mode, labeled DEFAULT and shows the current default AFD code to be used if no valid AFD
code is detected at the input
• In DELETE mode, labeled DELETED and always empty..
Change: Click the Change button to open the
Select AFD panel showing the available AFD codes
that could be used as the default. Click on one to
select it, then click Apply or OK at the bottom of the
panel.
Keep Last: click in this checkbox to use the last
detected AFD code at the input as the default code
to be used in the Auto mode when no AFD flag is
detected. This box is disabled in the Forced mode.
Config area
Presence: The status indicator turns Green when
AFD is detected on the input signal. On an SD
input, the AFD presence will indicate the presence
of the selected AFD source only, i.e. AFD, VLI or
WSS (for 625 sources only)
Source: Selects the source of AFD information –
options are AFD (SMPTE 2016), VLI of WSS (for
625 sources only).
Insertion Line: The Insertion line is used to select
on which line in the VANC the AFD packet (SMPTE 2016) will be inserted. It is not necessary to specify the
detection line since the card will automatically detect the incoming packet.
Insertion: The Insertion pull-down menu is used to enable or disable the insertion of AFD on the two outputs:
• On the HD output, the Ancillary Aspect Ratio packet will be inserted
• For SD outputs, a selection must be made when enabling insertion:
o 525 outputs – AFD (SMPTE 2016) or VLI
o 625 outputs – AFD (SMPTE 2016), VLI or WSS
.
Flags area
The Flags sub-section indicates which AFD flag is detected at the input and which flag is inserted at the
output.
