Sync Type
The Sync Type option sets the synchronization signal type of the output format. Press the Up or
Down button to show the current sync type. press the same button again to move to the next synctype.
Currently, the iScan supports seven sync types:
• Bi-level bi-level sync on green/luma
• Tri-level tri-level sync on green/luma
• CSync Composite Sync (on the H sync BNC connector)
• H+V+ positive Hsync and positive Vsync
• H+V- positive Hsync and negative Vsync
• H-V+ negative Hsync and positive Vsync
• H-V- negative Hsync and negative Vsync
Color Space
The color space parameter sets the color space of the output format. press the Up or Down button
to show the current color space. press the same button again to select the alternate color space.
Two analog color space options are supported: YPbPr (default) and RGB. Two digital color space
options are supported: RGB (default) and YCbCr (both 4:2:2 and 4:4:4).
Output Level
The output level setting allows the user to specify the levels of the output signal, either Video
(16-235) or PC (0-255)
• Video
• pC
Framerate Conversion
This parameter enables framerate conversion. There are two sets of controls, one for 50Hz input
sources and one for 60Hz input sources.
For 50Hz sources, if the original source material is progressive at 25Hz (uses 2:2 pulldown), the output
framerate can be source locked at either 50Hz or 75Hz. The 75Hz setting repeats each of the original
25Hz frames 3 times. You can also set the output frame rate to a specific value (unlocked mode).
For 60Hz sources, if the original source material is progressive at 24Hz (uses 3:2 pulldown), the
output frame can be source locked to either 48Hz, 60Hz or 72Hz. The 48Hz setting repeats each
original 24Hz frame 2 times, while the 72Hz setting repeats each frame 3 times. As with 50Hz
sources, you can also set the output frame rate to a specific value (unlocked mode).
press the Up or Down button once to see the current input rate. press the same button again to
switch input rate.
50 — > 50Hz input sources
60 — > 60Hz input sources
press the Enter button to select the input frame rate and change the output frame rate settings.
select the desired output frame rate setting by using the Up or Down button.
For 50 Hz input sources, the available settings are:
• 50Hz Lock source locked 50Hz
• 75Hz Lock source locked 75Hz
• Unlock unlocked
