Appears on front panel display as REGEN. Upstream regeneration is
used whenever no other local entry mode is enabled for a caption
channel. The Encoder's default Regeneration action is to regenerate the
caption data recovered from the HD video input. If no upstream HD
captioning is present, caption data from the SD video input will be used
instead.
The default Regeneration response is configurable by using the
commands listed in this section, and also by setting the Force 608 Up-
conversion GPI switch (see page 39).
<CTRL+A>! [ON/OFF] <ENTER>
Instructs the Encoder to either detect and potentially regenerate (default)
or ignore incoming VANC data from the HD video input. If the encoder
is set to ignore upstream VANC data, output signals will include only
caption data recovered and regenerated from the SD video input. Use
OFF to ignore upstream VANC caption data, and ON to resume
detecting upstream VANC caption data.
Instructs the Encoder to ignore incoming Line 21 data from the SD
video input in the specified caption channel. When Line 21 data in a
channel is ignored, output signals will not contain any caption data
recovered from the SD video input in that channel, even if there are no
other data sources available.
 Channel sets the incoming Line 21 channel to be turned off. This
parameter may be set for any NTSC Caption or Text channel.
Upstream XDS data cannot be turned off with this command.
