Description
Enable Pass-thru of VBI, ANC and Teletext data from
specified PIDs, instead of extracting them from SDI. Read
only parameter. Not supported in this release.
The source for Closed Captions data encoded as part of
the Video Stream (only applicable when Video Frame Rate
is 29.97 Hz)
Controls if the VBI Data Descriptor is inserted into the
PMT. Available only if VBI Descriptor Mode is set to User.
Controls if the VBI Teletext Descriptor is inserted into the
PMT. Available only if VBI Descriptor Mode is set to User.
Controls if the Teletext Descriptor is inserted into the PMT.
Available only if VBI Descriptor Mode is set to User.
Controls if the Legacy Proprietary Descriptor is inserted

User: The User defines the lines used to decode Video
Index.
Specifies which line contains the video index in field 1.
Specifies which line contains the video index in field 2.
Controls whether SMPTE 2016 data can be used as a
source for AR info.
Control what AFD code goes out when AFD is lost at input.
Indefinitely: Maintains previously received AFD code
indefinitely.
Default after Timeout: Maintains previously received AFD
code for period specified in Sustain Timeout, then drop to
default, i.e. code 1000.
Off after Timeout: Maintains previously received AFD code
for period specified in Sustain Timeout, then switch AFD
off.
Control how long previous AFD code is maintained. Zero
means drop to default immediately on loss.
Specify what code is passed to the output when reserved
AFD codes are received at the input.
Pass Through: Passes code through unchanged.
Code as 0000: Changes code to 0000.
