DDS 402
Two Input RGB Video Scaler
Features
DESCRIPTION
• High performance computer-video and component video scaler
The Extron DDS 402 Digital Display Scaler combines a high performance scaler with proprietary
technology to scale computer-video and component video signals to one of 41 output rates.
To optimize the output image quality, the DDS 402 is equipped with Extron's patented AFL™ Accu-RATE Frame Lock scaling technology.
• Inputs: RGBHV on female 15-pin HD with buffered local monitor output, RGBHV
or HDTV/component video on five female BNCs
• Outputs: RGBHV on female 15-pin HD, RGBHV or HDTV/component video on six
female BNCs
• 41 selectable output rates from 640x480 to 1400x1050, including HDTV 1080p —
To ensure maximum compatibility, the DDS 402 offers 41 user-selectable output rates,
including computer-video at up to 1400x1050 and HDTV at 720p, 1080i, and 1080p.
• Eight levels of horizontal filtering and eight levels of vertical filtering — Filtering
reduces jitter, improves image stability, and assures that minimal picture detail is
dropped during scan conversion.
• AFL™ - Patented Accu-RATE Frame Lock — A patented technology exclusive to Extron
that solves frame rate conversion issues experienced by video scalers. When video input
and output refresh rates differ, there are certain points in time when the two rates cross
over each other. The result is a glitch or image freeze on the display. AFL solves this
problem by locking the output frame rate to the input frame rate.
• Aspect ratio conversion — Ability to horizontally and vertically size any video input to
For upconverting inputs, the DDS 402 scales the RGB input to match the native resolution of
the projector or other display device, producing an undistorted, sharper looking picture. For
downconverting inputs, the DDS 402 accepts any computer resolution up to 1600x1200, with
horizontal scan rates up to 100 kHz and vertical scan rates up to 120 Hz, and converts it to
match the native resolution of a lower resolution display device.
The DDS 402 offers the following output rates: 640x480, 800x600, 832x624, 848x480,
852x480, 1024x768, 1280x768, 1280x1024, 1360x765, 1365x1024, 1400x1050, 576p,
720p, 1080i, and 1080p. This capability is crucial when the application demands that
computer-video from high resolution workstations be displayed on lower resolution displays
such as video walls, LCD, DLP™, D-ILA®/LCoS, and plasma. Using the DDS 402, video created
on SGI or Sun workstations can be viewed on plasma displays. The DDS 402 also features HDTV
720p, 1080i, and 1080p output resolutions for HDTV compatible displays.
meet a specific aspect ratio.
• Zoom capability up to 200% for video wall applications
• Brightness, contrast, horizontal and vertical shift, and horizontal and vertical
centering picture controls
• Input freeze control — Any input of the DDS 402 can be frozen using the freeze button
on the front panel. When the freeze button is pressed, it will light red. Once an input has
been frozen, the input to the unit can be removed, and the frozen output image will not
be lost until another source has been selected.
• 32 user memory presets for centering, sizing, filtering, contrast, and brightness
— Inputs one and two each support 32 auto-recall memory presets, based on the
incoming horizontal and vertical frequencies. These presets save sizing, centering,
detail, contrast, and brightness information for each source. Automatic recall of presets
can save an enormous amount of time and effort in fine-tuning displayed images.
• Front panel security lockout — This feature locks out all front panel functions except
The DDS 402 offers a zoom feature that makes the scaler ideal for use in video wall applications.
By pressing the zoom button and using the two rotary dials on the front panel, the image can
be zoomed in and out up to 200% while keeping the image in its original aspect ratio. This
feature lets users create a video wall effect using four displays and four DDS 402s. All four
of the DDS 402s can be zoomed to 200% and display one-fourth of the original image on
each display.
The rack-mountable DDS 402 has two video inputs for RGBHV, RGBS, RGsB, and component
video: one on a female 15-pin HD connector with a buffered local monitor output, and the other
on five female BNC connectors. Video output, as RGBHV, RGBS, and HD component video, is
available on five BNC connectors or a female 15-pin HD connector. The DDS 402 features eight
levels of horizontal and eight levels of vertical user-selectable filters. Horizontal filtering helps
prevent detail loss, while vertical filtering reduces flicker.
for input selection; all functions, however, remain active through RS-232 control.
• RS-232 serial control port — Using serial commands, the DDS 402 can be controlled
and configured via the Extron Windows®-based control program, or integrated into
third-party control systems. Extron products use the SIS™ - Simple Instruction Set
command protocol, a set of basic ASCII code commands that allow for quick and
easy programming.
• Rack-mountable 1U, full rack width metal enclosure
• Internal international power supply — The 100-240VAC, 50/60 Hz, autoswitchable
internal power supply provides worldwide power compatibility.
