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

analog component video sources. When

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
