Encoding
Various aspects of the operation of your encoder can be configured here.
Insertion
Selects the operating mode of the en-
coder and specifies whether data is be-
ing inserted.
VANC Readahead
Determines the processing delay (ex-
cluding any effects from running CC-
Match) between the input and output
of the encoder. Select "short" for one
fourth of a line of delay and "normal"
for one line of delay.
Force Upstream Regener-
ation
Manually returns the encoder to up-
stream "Regeneration" mode. This com-
mand can be used to resume passing
of upstream caption data whenever it is
being blocked by locally input caption
data. Any captioners or devices insert-
ing local data will be removed from cap-
tion mode immediately.
