Digital Scan Converter
DSC-1024G
The new Sony Digital Scan Converter, the DSC-1024G, makes possible the total integration of
different video and computer graphic signals.
With the innovative, high quality processing techniques used in the transcoding and scan conversion
functions of the DSC-1024G, up and down conversion between all major video signals and display
formats can now be achieved. This makes it possible to match the characteristics of a signal to a
particular application, for example an S-VGA signal can be converted to genlocked composite video
for compatibility with TV-standard systems.
The many features of the new DSC-1024G make it a truly versatile tool, a tool that is certain to have a
major impact on applications such as the large-screen display of computer generated images in
exhibition, conference and entertainment environments.

Universal System and Format Conversion
Line Doubling
The DSC-1024G combines the use of four line
interpolation to convert vertical scan lines with
variable offset sampling for horizontal scan lines,
and is designed to lock on to and display images in
various video formats. An input accepted in the
15.6 to 70kHz horizontal frequency range and the
50 to 120Hz vertical frequency range is output at
an industry standard 15.6kHz, 31.5kHz, 37kHz,
48kHz or 64kHz frequency.
Built-in Transcoder
The high-quality video decoder’s three line
digital comb filter serves to minimize the dot
interference visible on conventional television
displays. And the three-dimensional comb filter
reduces the random noise often visible when
playing NTSC standard video tapes and laser discs.
The transcoding function provides universal
conversions between video signal formats. The
DSC-1024G offers the user complete freedom in
changing to and from composite video,
Y/C, Y/R-Y/B-Y and RGB formats.
Line doubling significantly reduces the visible
line structure and horizontal line flicker in video
images. Doubling the number of scan lines, while
preserving the vertical data for each field, ensures
that even fast-moving images are naturally
reproduced. This assures higher quality
reproduction even when images are projected on
large video screens.

Automatic Input Signal Recognition
The DSC-1024G automatically recognizes the
input signal and converts it to
the selected output format, while
indicating the input signal
format. The OTHERS indicator
lights up when the input signal
has a non-standard line
frequency.
Genlock
Signal Format Indicator
When an NTSC or PAL signal is output, a
genlock function is available. This function
syschronizes the NTSC or PAL output signal to a
black/burst signal input to the DSC-1024G as a
reference signal.

Sony Stays True to the Original
Variable and Offset Sampling
80MHz quality sampling performance at a 40MHz
sampling rate, making video conversions that
remain faithful and true to the original signal.
Compared to NTSC and PAL signal
bandwidths of around 6 to 7MHz, computer video
bandwidths range from around 15MHz for VGA to
over 50MHz for SVGA. The DSC-1024G switches
the sampling rate and low-pass filtering in 6 steps
to provide the appropriate signal processing for
each signal bandwidth over this entire range of
source signals.
Variable offset sampling, which changes phase
for each line, is used on very high-frequency
bandwidths such as the SVGA. The result is
High-density Vertical Interpolation
Interpolation and compensation are used to
increase and decrease the number of scan lines
when converting between signals of different
resolutions.
When down converting, the DSC-1024G uses
four line interpolation to combine the original data
of four lines to a single line. Interpolation is

performed on the previous three lines and the next
line using a system of weighted averages. The
process is continued for the full screen. In contrast,
the conventional scan methods simply leave out
entire lines of information. This is why the
DSC-1024G can create images with highly accurate
details.
When up converting, two line interpolation
uses the data of adjoining lines to calculate the
transitional area. This contrasts with the simple
double scan technique of traditional methods. The
result is image reproduction featuring high
resolution.

increases image detail
by sharpening edge
detail when displaying
computer signals.
