Extron Digital Scaler

Description

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.
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.
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.
