: Enables horizontal and vertical alignment of
video signals to a genlock signal. Effective on both
synchronous and asynchronous signals.
Line
: Locks the video signal (within ±1/2H) to a
genlock signal. Output delay is as shown in the
below table. Effective only when video signal is
synchronous to the genlock signal.
AVDL/ Line(Minimum)
: Locks the video signal to a
genlock signal with a delay depending on the format
as shown in the below table. Effective only when
video signal is synchronous to the genlock signal.

With 4K Mode enabled (see Section 4-2
. “Video Block”), all 4 FS settings under the same FS group
(FS3-6 or FS7-10) are linked.
For 3G Level-B signals, frame delays caused by FS control are different between video and
ancillary data areas.

FA-1010 adopts the following values for 1H when outputting 3G Level-B video signals:
2200clk (14.83us) for 59.94Hz
2640clk (17.78us) for 50Hz
