V ANC O UTPUT • G ENERATED VANC: When selected, it indicates that Intuition XG is operating in
generated VANC output (This setting supersedes the VBI Passthrough mode).
Intuition XG generates the VANC using selective passthrough of some VBI
lines from Video In or from Clips (in NTSC and PAL mode only for clips),
selected ancillary data packets are also generated for CDPs and AFD codes
and inserted into some VANC lines, and some ancillary data packets are
passed through from Video IN to the corresponding VANC output line.
• A NCILLARY CDP L INE : In generated VANC mode, this property specifies which
VANC line should carry caption distribution packets (CDP). If the line specified
is outside the valid range (same range as for Passthrough lines except in
NTSC mode where line 6 is not permissible since it is only available on Field2),
then CDPs will not be managed by Intuition XG. Use -1 to disable CDP
processing (any line out of range will disable the processing, but using a
negative value avoids logging it as an error). Note that CDP is frame based
and will only be inserted in the first field of each frame. Also note that even if
the source for the captions is a “line21” CEA-606 stream, Intuition XG will
create CDP packets with only the CEA-608 compatibility bytes and if no
caption stream is available, Intuition XG will create empty CDP packets.
• A NCILLARY D OLBY L INE : This feature is not yet supported by Intuition XG and
apart from range checks, any number specified will be ignored.
• A NCILLARY AFD L INE : This feature is not yet supported by Intuition XG.
• A NCILLARY SDP L INE : Specifies the line of the VANC on which SDP are
inserted.
• L INE 21 C APTIONS : When selected and Intuition XG’s output resolution is
NTSC, tis specifies that Intuition XG should extract the CEA-608 caption
stream and encode it on line 21(field1 and field2). If no caption stream exists,
then the lines will not be generated. Note that if there is a field 2 CEA-608
caption but no field 1 captions, the Intuition XG generates an “empty” field 1
CEA-608 caption with only “line21” clock run-in (SMPTE requirement).
V ANC P ROCESSING AFD processing is enabled when the V ANC O UTPUT section’s G ENERATED VANC
option is enabled and the A NCILLARY AFD L INE setting is valid line number. Intuition
XG must insert an AFD ancillary data packet into the VANC.
•
V IDEO I N A: U PCONVERT CEA-608 TO CEA-708: When enabled, this parameter
converts the CEA-608 (Line 21) closed caption data on Video A input into
native CEA-708, which is required for digital television broadcast.
• V IDEO I N B: U PCONVERT CEA-608 TO CEA-708: When enabled, this parameter
converts the CEA-608 (Line 21) closed caption data on Video B input into
native CEA-708, which is required for digital television broadcast.
• D EFAULT AFD V ALUE : Intuition XG inserts the D EFAULT AFD V ALUE into an
AFD ancillary data packet under 2 conditions. The first is if Intuition XG cannot
find any AFD values within the specified source (videoin or clip). It will
substitute the D
EFAULT AFD V ALUE instead. The second case is if you selected
the I NITIAL AFD S OURCE to be V ALUE and selected D EFAULT from the drop-
down box.
