Linux—Using the Graphics to Video Out Control Panel
Adding a Delay to the Signal
You
can
introduce
a
slight
delay
in
the
genlocked
or
frame
locked
SDI
output.
For
example,
if
delivery
of
video
from
other
equipment
is
delayed
because
of
greater
cable
length,
you
can
introduce
a
delay
in
the
SDI
output
from
this
card
so
that
both
deliveries
are
in
sync.
To
introduce
a
synchronization
delay:
1
Open
the
Graphics
to
Video
Out
page
and
click
Synchronization
Options
.
2
In
the
Synchronization
Delay
group
box,
introduce
delays
in
the
HSYNC
and
VSYNC
signals
as
needed
by
clicking
the
appropriate
up
and
down
arrows.
You
can
also
enter
values
directly
into
the
text
boxes.
