Specific ANC Processing
The remainder of the ANC tab controls how ancillary data is inserted in the output when HANC
and/or VANC pass through is not enabled.
ANC Processing Overview
For each packet type the user can control the insertion position.
To configure the processing of specific ANC types
1. From the Device View in DashBoard, select the ANC tab.
2. For each packet, select how the card processes the ANC data by selecting an option from
the
Action field. Refer to Table 9.14 on page 9-18 for a list of options.
3. Specify the line to insert the ANC data packet as follows:
• Use the Insertion Line menu to select a line to insert the specified ANC packet on.
The default is 12 for each packet. Note that all packets are inserted in VANC, except
for timecode in non-SD formats which are inserted in the HANC.
• Note that if more than one packet is to be inserted in the same line, the packet with
the lowest insertion order number will be inserted first.
4. Specify the insertion order for the data packet as follows:
• Use the Insertion Order menu to define the hierarchy of the packets insertion.
• Note that the lower the number, the higher priority the packet is given. For example,
by default, the AFD packet is set to be inserted first (1), and Compressed Audio
Metadata is inserted fourth (4).

3. Use the Input Line Number menu to specify which line to search in the input signal for
Video Index (VI) data. Choose from the following:
• Auto — The card searches each line in the input signal for the VI.
• Default — The card searches only line 11 in the input signal for the VI.
Note
— It is recommended to set the Time Code and Audio Metadata fields to
Disable when converting between interlace and progressive video.
