Closed Captioning

• Closed Captioning Source

Selects the video format that carries the Closed Captioning (CC) video
stream as follows:

Input Video: Sets the 9035 to receive CC stream from the currently

selected input format (as selected using the Video Signal Controls
functions.

Analog SD: Sets the 9035 to receive analog SD CC stream on the

analog inputs (Y/composite, Pr/C, and Pb inputs) regardless of
video input source.

• HD/SD-SDI: Sets the 9035 to receive either HD or SD CC stream on

the SDI input regardless of video input source.

• 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.

• 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.

• 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. 3-8)
for more information.
