The following functions are available:
•
Sync Selection — This function applies only to Analog RGB inputs. The
DCS-200 automatically selects the syncs for digital sources, composite, S-video,
and YP
b
P
r
inputs. For these 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

P
r
analog component video sources. When
DCS-200 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

The DCS-200 supports saving up to 64 input configuration files in non-volatile memory,
each of which is available to the nine physical inputs (
1 through 8 and SDI ).
Input configuration files contain settings that govern everything from pixel resolution to
aspect ratio and color balance — any setting you can view or change using the
Input
Menu . By default, an input’s configuration file number is the same as the number of the
input — Input 1 is assigned to configuration file number 1, and so on. You can set, delete,
save, or recall the configuration file for an input. You can associate any number of saved
files to any number of inputs.
When you change the configuration file for an input, the timing in the new configuration file
