settings from the current input, and restore the input's format parameters from the system's

Sync Selection — This function applies only to Analog RGB inputs. The digital
input sources have embedded syncs, and the composite, S-video, and YP
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
ACS-2048 detects Macrovision copy protection on the incoming YP
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
