AFD/WSS/VI sub-tab provides prioritized and gated input monitoring for
AFD, WSS, and/or VI formats. Also provides translation between input
and output AFD, WSS, and VI ARC formats.
Note:
• Active ARC control is unavailable. The ARC control/convert function only manipulates output SDI ARC codes and has no
local effect on card output aspect ratio.
• Line number control available only for AFD format. WSS and VI use fixed line numbers per applicable standards.
• Some AFD codes are not supported in WSS and VI formats. Refer to AFD/WSS/VI Transition Matrix section for more
information.
Input Format Status Displays
Displays the current status and contents of the three supported ARC
formats are shown to the left.
• If a format is received, the current formatting code and description is
displayed (as shown in the example).
• If a format is not receiving data, Not Present is displayed.
Input Mapping When received ARC code is received, applies H/V coding as follows:
• Follow Trigger — Uses the ARC coding inherent in the received
triggering ARC.
• 4x3 ARC Codes — For received triggering formats coded as 4x3,
applies the H/V coding selected in this drop-down.
• 16x9 ARC Codes — For received triggering formats coded as
16x9, applies the H/V coding selected in this drop-down.
Note : Settings performed here can be applied directly to the output video,
or the settings applied here can be custom modified if desired for any of
the eleven 4x3 codes and any of the eleven 16x9 codes available here
using the AFD Map sub-tab. Refer to section “AFD/WSS/VI Transtion
Matrix” on page 3-25 for more information.
Input Triggering Controls Individual ARC format input controls allow accepting or rejecting received
ARC formats as follows:
Trigger on AFD:
• Off rejects AFD-coded triggering.
• On allows trigger on AFD.
Trigger on WSS:
• Off rejects WSS-coded triggering.
• AFD allows triggering on AFD-coded WSS.
• ETSI allows triggering on ETSI-coded WSS.
Trigger on VI :
• Off rejects VI-coded triggering.
• AFD allows triggering on AFD-coded WSS.
• SMPTE allows triggering on SMPTE-coded WSS.
Note : If multiple formats are present on the input video, AFD pre-empts
other formats, followed by WSS or VI (as set by the WSS/VI Priority
control).
