VGA - to - DVI Video Scaler
1. Introduction
1.1 General
The SC-VD-2 is a high performance
PC/HDTV scaler that accepts analog RGB
inputs (VGA or Component) and converts it
to DVI-I (digital + analog) output.
The input to the SC-VD-2 is analog PC or
HDTV signal (RGBHV, YPbPr, or YCbCr).
The output of the SC-VD-2 is digital +
analog PC or HDTV DVI signal with a format of digital RGBHV bit-stream
plus analog RGBHV, known as DVI-I (Integrated digital and analog).
The input resolution is automatically detected while the output resolution
and refresh rate can be selected through OSD menu and front panel push
buttons.
DVI output enables an all digital rendering of video without the losses
associated with an analog interface and is ideal for use with digital displays
such as LCD, plasma or DLP projectors.
The SC-VD-2 Video Processor combines the functions of a video scaler,
scan-converter, and format transformer and is packed into a compact and
durable metal housing with easy-to-use touch buttons.
The controls include input/output setup picture adjustment, H/V phase
adjustment, System information and many other advanced options.
The SC-VD-2 allows you to specify a resolution and refresh rate for its
output. Then it will output a steady (uninterrupted) DVI 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 with DVI output option. 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.

Model SC-VD-2
1.2 Features
• Converts analog VGA from any PC (or component from any DVD
player) to Digital DVI output.
• Ideal for use with digital displays such as LCD, plasma, or DLP
projectors.
• Digital output reduces losses associated with analog signals.
• 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.
• 50 MB Video memory for real-time frame rate 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
• 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.
(VGA/SVGA/XGA/SXGA) + HDTV(480p/576p/720p/1080i)
2. Installation
2.1 Input connection
The SC-VD-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-VD-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-VD-2.
The SC-VD-2 can automatically detect the mode and resolution of the
PC/HDTV input (The mode can also be forced via OSD menu).

2.2 Output connection
The SC-VD-2 can output a variety of PC resolutions and HDTV
progressive resolutions, in both digital and analog format.
To use the SC-VD-2's digital output select DVI-D in the Output Setup of
the menu, and use a DVI cable to connect the DVI output of the SC-VD-2
to the DVI input of a display monitor, or HDTV device.
To use analog output of the SC-VD-2, select DVI-A in the Output Setup of
the menu, and use the DVI to VGA adaptor or cable to translate the analog
outputs in the DVI connector into VGA configuration to connect to a VGA
monitor or to connect to the YPbPr input of a HDTV device through a
VGA to YPbPr/3RCA adaptor cable.
2.3 Connection Block Diagrams
In the above diagrams the output of the SC-VD-2 is set to digital DVI. If
you set the output to Analog DVI, you can use an analog LCD monitor and
or HDTV; however you will need adapters or cables for connection to the
unit.

3.2 Menus and Adjustments
Pressing the Menu button will bring up the OSD menu controls on the
screen as follows:
¾ Input set up
¾ Output set up
¾ Picture Adjust
¾ HV Adjust
¾ OSD Adjust
¾ System Information
¾ Auto Adjust
¾ Exit
Use + or - to move the arrow cursor to your desired selection, then press
MENU to confirm your selection and enter into that sub menu.
When selected, a sub menu of clock, phase, and input

mode is shown.
YPBPR …
Use + or - to choose the parameter your want to adjust and then press Menu
(Enter) to highlight your selection. Once a parameter is high-lighted use +
or - to increase or decrease the setting value. Press Menu (Enter) again to
leave the setting. Move the arrow to exit then press Menu/Enter to Exit.
Clock: Used to adjust for optimal input clock frequency for a stable picture.
Pressing + narrows the width of the picture toward the left. Pressing extends the width of the picture toward the right.

Phase: Used to adjust for lowest noise of the picture (edge tearing).
YPbPr RGB: The SC-VD-2 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 selected, a sub-menu appears for the DVI
