Closed Captioning

Provides support for closed captioning setup.

Note: When receiving HD-SDI, both CEA 608 and CEA 708 are supported, with CEA 608 and CEA 708 (containing CEA 608

packets) converted to line 21 closed captioning on outputs down-converted to SD (on up-convert of SD, only CEA 608

closed captioning is generated).

• Closed Captioning Input Status Displays incoming Closed Captioning status as follows:

• 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.

• The closed captioning function does not support PAL closed

captioning standards.

• Closed Captioning Output Insertion Control Turns on or turns off the Closed Captioning on the output video.

Note: • When set to On, closed captioning is set to standard default line

number. See Ancillary Data Line Number Locations and Ranges

(p. 3-9). (SD output is locked to line 21.)

• The card does not check for conflicts on a given line number.

Make certain selected line is available and carrying no other data.

• Closed Captioning HD Output Line 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. 3-9) 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.
