Input Menu
• Input Type — sets the type of input connected to the ScreenPRO-II. Available
choices
change depending on the selected Format, and the choice affects the
Color Space selection. Input types include:
~ RGB
~ YP
b
P
r
~ Composite/S-Vid
~ HD SDI
~ SDI
• Color Space — sets the input’s color space, either SMPTE or RGB. The system
automatically sets the Color Space based on the selected
Format and/or Input
Connector
and Input Type — but in some cases, color space can be changed.
• Sampling Mode — sets the sampling mode for the selected input.
~ When 1:1 Sampling is selected, the system provides pixel-for-pixel
sampling, and generally better image quality.
~ When Oversample is selected, the system performs multiple samples
for every pixel, with a resulting “softer” image.
• Contrast — sets the input’s contrast. Adjustment range: 75% to 125%.
• Brightness — sets the input’s brightness. Adjustment range: 75% to 125%.
• Gamma — sets the input gamma, enabling you to match the gamma of the
source. Adjustment range: 1.0 to 3.0.
• Input Sync Type — sets the type of sync used by the selected source. Choices
include:
~ H/V
~ CSync (composite sync)
~ SOG (sync on green)
~ Auto
• Pulldown Compensation — (On/Off) This function is applicable only for
standard video (component, s-video, composite) inputs. The default mode is off.
The feature should be turned on to process video derived from film material.
• Sync Slice <mv> — This function selects the sync comparator threshold for
RGsB (RGB with Sync on Green) or YP
b
P
r
analog component video sources.
The value ranges from 20mV to 280mV and is adjustable in steps of 10mV. The
default value is 160mV.
When the ScreenPRO-II Controller detects Macrovision
®
copy protection on the
incoming YP
b
P
r
NTSC/PAL video, the Sync Slice value is repositioned to 60mV to
account for the reduced amplitude sync pulse.
• Sharpness — sets the input’s sharpness. Adjustment range: -10 (very smooth) to
10 (very sharp).
Note
The default Sync Slice level has been optimized for virtually
all sources that will be encountered and should rarely, if ever,
require adjustment. However, you can adjust the
level to
improve sync detection and synchronization in cases of
extremely noisy RGsB or YP
b
P
r
video signals.
