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).
