Other Data Types
This section provides additional information on other data types that the UDC-8625A series
manages.
AFD and Video Index
Keep the following in mind when configuring the AFD and VI options:
• When disabled, the aspect ratio conversion still occurs as specified in the ARC tab, but
there is no AFD packet inserted in the output. Otherwise it is inserted according to the
ARC tab.
• If AFD and Video Index is set to Disable , and the Output Line Number value in the
Video Index Config area differs from the insertion line used for the AFD and Video
Index packet, VI will be inserted on the line specified in the Output Line Number
drop-down menu. This means that if the output line is anything other than Follow Input
or Default , any other VANC data on that line will be overwritten.
For More Information on...
• the VI data configuration options, refer to the section “ Video Index (VI) Processing ” on
page 5-4 and “ Configuring a Profile ” on page 4-7.

The user can specify whether timecode is passed or disabled:
• If the input is not synchronous to the output, select Disable from the Action menu of the
ANC tab.
• If converting between progressive and interlaced, select Disable from the Action menu
of the ANC tab.
• When pass is enabled, the timecode will be inserted in VANC for SD outputs, and HANC
for all other formats.
• If the input is not synchronous to the output, data will be dropped (but not duplicated
1
) as
part of the frame sync behavior.

• If the input is not synchronous to the output, select Disable from the Action menu of the
ANC tab.
