Ancillary Data Line Number Locations and Ranges
				Table 3-1 lists the default output video VANC line number locations for
				various ancillary data items processed or passed by the card.
	Table 3-1 9084 Ancillary Data Line Number Locations/Ranges
						Default Line No. / Range
	Item				SD			HD
	AFD			12 (Note 2)			9 (Note 2)
	ATC_VITC			12 (locked)			9/8 (Note 2)
	ATC_LTC			—			10 (Note 2)
	SDI VITC Waveform			14/16 (Note 2)			—
	Closed Captioning			21 (locked)			10 (Note 2)
	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

Because line number allocation is not standardized for all ancillary items, consideration should be given to all items when performing set-ups. Figure 3-8 shows an example of improper and corrected VANC allocation within a 525i5994 SD-SDI stream.

	AFD Insertion	SD ATC_VITC = 12

SD ATC_VITC = 12		AFD = 12
	VANC line 12

Conflict between fixed SD ATC_VITC and added AFD both on VANC line 12
