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
525i
625i
ATC_VITC = 9/8
CC = 10
Dolby Metadata = 13

ATC_VITC = 9/8

Table 3-1 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 shows an example of improper and corrected VANC allocation within an
HD-SDI stream.
