VGA / HDTV Video Processor
1. Introduction
1.1 General
SC-VGA-2 is a high-performance
universal VGA / HDTV to VGA /
HDTV Scan Rate converter. It also
offers the capability to "Mirror" the
VGA input signal on the X-axis.
The Video Processor combines the
functions of a video scaler, scanconverter, and format transformer and
is packed into a compact and durable
metal housing with easy-to-use touch buttons. The SC-VGA-2 is
controlled via push button and OSD menu.
The controls include input/output setup picture adjustment, H/V phase
adjustment, System information and many other advance options.
The SC-VGA-2 allows you to specify a resolution and refresh rate for
its output. Then it will output a steady (uninterrupted) VGA signal to
your display device at your specified rate regardless of the input. This
effectively allows any VGA switch, such as HRT's VS-2 or VS-4, to
become a seamless switch. The output timing is constant regardless of
what is happening at the input. So when you switch from one input to
another, the display device does not see any interruption in the signal
coming to it.
ss
1.2 Features
• The resolution of any PC or HDTV video signal can be scaled up or
scaled down to any other PC or HDTV resolution. It can also
change the frame rate of the output.
• Large Video memory for real-time frame rate capture &
conversion.
• Signal format conversion between RGBHV and YPbPr.
• Input: PC (VGA/SVGA/XGA/SXGA) + HDTV(480i 576i 480p
567p 720p 1080i), @ 60 to 85 Hz
• Output: PC
• Automatically detects input mode and timing parameters
(VGA/SVGA/XGA/SXGA) + HDTV(480p/576p/720p/1080i)

Model SC-VGA-2
• Allows fine-tuning the output picture to optimum through
adjustment of sampling clock, phase, and position on screen.
• Easy- to- use push buttons and OSD menu control.
• Can Mirror VGA output Horizontally; perfect for teleprompting
and rear projection systems
2. Installation
2.1 Input connection
The SC-VGA-2 can accept both PC and HDTV inputs. When
accepting a PC input use the 15-pin D-sub cable to connect the output
of a PC device to the input connector labeled PC/HDTV on the back of
SC-VGA-2.
When accepting a HDTV input use a15-pin D-sub to YPbPr/3 RCA
cable to connect the YPbPr/output (or YCbCr) of a HDTV device to
the PC/HDTV input connector of the SC-VGA-2.
The SC-VGA-2 can automatically detect the mode and resolution of
the PC/HDTV input.
2.2 Output connection
The SC-VGA-2 can output a variety of PC resolutions as well as a
number of HDTV resolutions.
When one of the PC resolutions is selected as output, use the 15-pin DSub VGA cable to connect the PC/HDTV output of the SC-VGA-2 to
the VGA input of a display monitor.
When one of the HDTV resolutions is selected as the output, use a 15pin D-Sub to YPbPr/3 RCA adaptor cable to connect the PC/HDTV
output of the SC-VGA-2 to the YPbPr input of a HDTV device.
________ Note _______
If you need a 2nd un-altered version of the input Video, please
use a Model 200 Video Splitter at your video source. For
example when the SC-VGA-2 is set to mirror the video, you can
have a mirrored and a non-mirrored output.

3.1 Front and Rear Panels
3.2 Menus and Adjustments
Pressing the Menu button will bring up the OSD menu controls on the
screen as follows:
5
Model SC-VGA-2
Use +,or - to move the arrow cursor to your desired selection, then
press MENU to confirm your selection and enter into sub menu.
When it is selected, a sub menu of input signal
IInnppuutt sseett uupp -
capture adjustments will appear.
-
Use +,- to choose the parameter your want to adjust and then press the
Menu (Enter) to highlight your selection. Then use +,- to increase or
decrease the setting. Press Menu (Enter) again to leave the setting.
“CLOCK” changes the number of samples per display line. The unit
samples the video at the nominal pixel rate. For example a 1024x768
resolution signal is sampled 1024 times during the active video time.
Changing the clock has the effect of adjusting horizontal size of the
displayed output. When you change this setting; the right edge of the
video moves to the left (shrinking the width) or to the right (expanding
the width).
“PHASE” refers to nanosecond timing position of each sample taken.
This adjustment can be used to align the pixels grabbed by the SCVGA-2 to those created by the VGA card in the PC.
“H-ADV” refers to the point at which active video sampling starts. Its
effect is to start sampling earlier thereby showing more of the left edge
of the image. Use this adjustment if the left edge of the image seems to
be cut off and you don’t seem to be correct it by the H V ADJUST
menu selection. Some Video cables or video amplifiers may cause
different delay to the RGB color signals as compared to the H&V sync
signals, this could cause the left edge of the image to be shifted from
nominal; this adjustment is provided to give the user 10 pixel advanced

sampling adjustment range. Using 5-coax extension cables (rather than
3 coax+ 4 TP) maintains the timing differential in long cable runs.
Under normal condition the unit automatically detects and shows the
input format as YPbPr or RGB. However, you can manually select the
YPbPr or RGB to match the format of your input. Selecting a format
that doesn't coincide with your input will result in an abnormal picture.
When it is selected, a sub-menu appears, that

When it is selected the following sub-menu appears.
-
Use + - to adjust the best horizontal and vertical position.
If your unit has a “SIZE” menu choice, you have the options of OVER
and UNDER selected by the + and – buttons. Normal setting is OVER
which stands for “OVER SCAN”. It fits the output screen perfectly to
your display borders. When converting a PC input to HDTV output
(480p, 576p, 720p, or 1080i) you may crop some of the edges of the
PC signal. In this case select the UNDER choice which stands for
“UNDER SCAN” Note that the under scan feature only works for
certain input/output resolution combinations. For example; with an
input resolution of 800x600 and output resolution of 720p, the under
scan feature shrinks both the width and height of the output. Also if the
input resolution is 1280x1024, output settings of 480p and 576p will
have full under scan functionality. At other input/output combinations,
the under scan may only affect the height or width or neither!

Notes
The default output resolution of the SC-VGA-2 is XGA @
60Hz.
The unit has non-volatile memory and memorizes all your
settings before power off and recalls those settings on next
power on.
Quickly Jumping to XGA or 480p Output
At any time, pressing + and - buttons simultaneously for a few
seconds will reset the output resolution to XGA@60Hz, and other
settings back to factory default values. Pressing the Menu and –
together for a few seconds will choose 480P output mode
4. Troubleshooting
There are no field serviceable parts or circuits in the device. If you
think that the device is malfunctioning (or you have no picture output),
please first try to reset to factory default settings by pressing the “+”
and “-” buttons (or “menu” and “-” buttons) simultaneously for 2
seconds (See above).
