Ancillary Data Line Number Locations and Ranges
Table 3.2 lists typical default output video VANC line number locations for various ancillary data
items that may be passed or handled by the card.
Because line number allocation is not standardized for all ancillary items, consideration should be
given to all items when performing set-ups.
Figure 3.6 and Figure 3.7 show an example of
conflicted and resolved VANC allocation within an HD-SDI stream.
Figure 3.6 Example VANC Line Number Allocation — Conflict
Figure 3.7 Example VANC Line Number Allocation — Resolved

Notes:
1. The card does not check for conflicts on a given line number. Make certain the selected line is available and carrying no
other data.
2. While range indicated by drop-down list on GUI may allow a particular range of choices, the actual range is
automatically clamped (limited) to certain ranges to prevent inadvertent conflict with active picture area depending on
video format. Limiting ranges for various output formats are as follows:
Format Line No. Limiting Format Line No. Limiting Format Line No. Limiting
525i 12-19 720p 9-25 1080p 9-41
625i 9-22 1080i 9-20
