BBG-1002-UDX Function Menu List and Descriptions
Provides support for closed captioning setup.Also
provides controls for setting closed captioning absence
and presence detection thresholds.
Closed Captioning
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.
• 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 device as normal.
• The closed captioning function does not support PAL closed
captioning standards.
• Closed Captioning Remove/Regenerate
and HD Insertion Line Controls
Allows removal of closed captioning packets and regeneration of packets.
This is useful where closed captioning must be moved to a different line
than that received on.
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.
• Conflicts on a given line number are not checked. Make certain
selected line is available and carrying no other data.
• Presence/Absence Check Controls
Displays CC presence and/or absence event status. This status can be
propagated to the Presets > Event Triggers tab controls to issue a
device GPO or other command when CC presence/absence events are
detected.
Controls for both presence and absence provide for a holdoff time (in
seconds) where, when time is exceeded, an event is to be considered a
valid alert event.
