Consequences:
Since VLI data is transmitted on line 11 for 625 output signals, it shall be replaced by any
down-converted teletext data to be inserted on line 11.
•
Teletext/Timecode line insertion conflict. Refer to manual.
[message in red letters]
Conditions:
HD/SD to SD (625 only), same line enabled for teletext and Timecode 1 or Timecode 2 (duplicate
time code included) insertion
Consequences:
Since DVITC timecode and teletext cannot reside on the same line, timecode data shall be
replaced by any down-converted teletext data.
•
Timecode 2 will overwrite Timecode 1 insertion. Refer to manual.
[message in red letters]
Conditions:
HD to SD, same line set for Timecode 1 and Timecode 2 insertion (duplicate timecode included)
Consequences:
Any LTC type incoming timecode will be inserted over any VITC type incoming timecode
specified by the Timecode 2
SD Insertion Line
parameter.
•
AFD insertion will overwrite incoming TC/Teletext on insertion line. Refer to manual.
[in blue letters]
Conditions:
SD to SD, both AFD and VBI insertion enabled
Consequences:
Since timecode and SMPTE-2016 AFD cannot reside on the same line, any incoming
timecode is blanked and the AFD data is inserted. This occurs on the selected AFD insertion line.
•
Dolby Metadata insertion will overwrite incoming TC/Teletext on insertion line. Refer to manual.
[in blue letters]
Conditions:
SD to SD, both Dolby Metadata and VBI insertion enabled
Consequences:
Since Dolby metadata and ancillary data like timecode cannot reside on the same line, any
incoming timecode is blanked and Dolby metadata is inserted. This occurs on the selected Dolby metadata
insertion line.
•
Dolby Metadata/AFD insertion will overwrite incoming TC/Teletext on insertion line. Refer to manual.
[in blue
letters]
Conditions:
SD to SD, both Dolby Metadata and AFD including VBI insertion enabled
Consequences:
Since Dolby metadata, AFD, and ancillary data like timecode cannot reside on the same line,
any incoming timecode is blanked and Dolby metadata or AFD is inserted. This, of course, shall occur on the
selected Dolby metadata or AFD insertion line.

Closed Caption section
Presence:
this icon turns green in the presence of incoming
EIA-708-B or EIA-608-B closed captioning data when an
3G/HD source is installed or when line 21 closed captions are
detected when an SD source is installed.
Insertion:
The pull-down is used to select between
Auto
or
OFF
. Availability of these controls is affected by whether or
not Line 21 of the input SD or output SD signal has been
configured as blanking; see
SD Input/Output Config
subsection below for details.
When
Auto
is selected, closed captioning information is
processed as follows:
3G/HD to SD Downconversion:
As described in EIA-708-B, closed captioning within a 3G/HD
signal is embedded in the form of ANC packets. The XVP-
3901 extracts all NTSC legacy (compliance) closed captions
