• If closed captioning is present, a message similar to the example shown
left is displayed. Also displayed is the VANC line number of the incoming
closed captioning packet (or SD waveform-based VANC line number).
• If no closed captioning is present in the video signal, Not Present or
Disabled is displayed.
Note: • Packet closed captioning status Captioning Rejected Due To
message can appear due to the items described below. The
closed captioning function assesses cdp_identifier,
cdp_frame_rate, ccdata_present, and caption_service_active
items contained in the packet header to make the determinations
listed below. Refer to CEA-708-B for more information.

No Data ID
• caption service is marked as inactive display indicates bit in
packet from upstream source may inadvertently be set as
inactive. In this case, closed captioning data (if present) is still
processed and passed by the card as normal.
• The closed captioning function does not support PAL closed
captioning standards.
Selects the VANC line number (9 thru 41) for the closed caption data
when the output is HD.
Note: • Although the output line drop-down will allow any choice within the
9 thru 41 range, the actual range is automatically clamped (limited
to) certain ranges to prevent inadvertent conflict with active
picture area depending on video format. See Ancillary Data Line
Number Locations and Ranges (p. 3-8) for more information.
• The card does not check for conflicts on a given line number.
Make certain the selected line is available and carrying no other
data unless existing metadata is to be intentionally overwritten.
