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.
