Processing Menu (sample)
The following functions are available:
•
Sync Selection
— This function applies only to
Analog RGB
inputs. The digital
input sources have embedded syncs, and the composite, S-video, and YP
b
P
r
inputs always take sync from the Y (or composite) channel. For these digital
inputs, the value field indicates
[N/A]
.
The sync choices are
Auto
,
H/V
(horizontal/vertical sync),
CSync
(composite
sync) and
SOG
(sync on green).
~
In
Auto
mode, the system finds sync in any of the three possible
sources.
•
If one of the sources is chosen, the system uses only that input
as a sync source.
•
If the system does not find sync at that source, it acts as if it is in
Auto
mode.
~
The default selection for Analog RGB inputs is
Auto
.
•
Pulldown Compensation
— This function only applies to standard video
(component, s-video, composite and SD/HD SDI) inputs. The mode, which
detects the 3:2 film pulldown sequence, should be turned
ON
to properly process
video derived from film source material.
~
Adjustment range
: OFF, ON
~
Default
: OFF
•
Sync Slice
— This function selects the sync comparator threshold for RGsB
(RGB with Sync on Green) or YP
b
P
r
analog component video sources. When
ACS-2048 detects Macrovision copy protection on the incoming YP
b
P
r
NTSC/PAL
video, the
Sync Slice
value is automatically repositioned to 60mV to account for
the reduced amplitude sync pulse.
~
Adjustment range
: 20mV to 280mV, adjustable in steps of 10mV
~
Default
: 160mV

From the
Input Menu
, select
Reset Config
to remove all user-entered configuration
settings from the current input, and restore the input’s format parameters from the system’s
internal library values. When you select the function, you will be prompted to reset (
SEL
)
or continue without resetting (
ESC
).
Note that if the current format was derived as a best guess, those “guess” values are
restored.
