1-3 DVS 204 • Introduction
Buffered video outputs — Six rear-panel BNC connectors and one VGA-type
15-pin HD connector provide connections for RGB output. Both outputs
(the BNCs or the 15-pin HD connector) are active at all times for
simultaneous output.
Three ways to control the scaler — The scaler’s front panel, a computer or other
RS-232 control device, or the optional IR 901 remote control can all be used
to control the scaler.
Scaled outputs — The DVS 204 offers 59 different output rates.
RS-232 configuration — The DVS 204 can be configured by using the Extron
control software for Windows, or by using a third party control system.
Accu-RATE Frame Lock ™ — The Extron Accu-RATE Frame Lock™ eliminates
artifacts from scaled motion video by eliminating frame rate conversion. It
locks the output frame rate to the input frame rate of the active input. The
result is a switching system that eliminates image tears and other artifacts
from motion video.
Dynamic Motion Interpolation ™ (DMI ™ ) — This video processing technique is
an advanced motion prediction and compensation method that treats
motion content and still content with different algorithms to yield high
fidelity images.
3:2 pulldown detection for NTSC and 2:2 film detection for PAL video sources
— These advanced film mode processing features help maximize image
detail and sharpness for video sources that originated from film. When
film is converted to NTSC video, the film frame rate has to be matched to
the video frame rate in a process called 3:2 pulldown. Jaggies and other
image artifacts can result if conventional deinterlacing techniques are used
on film-source video. The DVS 204’s advanced film mode processing
recognizes signals that originated from film. The DVS 204 then applies
video processing algorithms that optimize the conversion of video that was
made with the 3:2 pulldown process. This results in richly detailed images
with sharply defined lines. A similar process is used for PAL film-source
video.
Versatile mounting options — The DVS 204 is 1U high, and a half rack wide. It
is rack mountable, or it can be placed on a table or other furniture. Rubber
feet are included.
Options and accessories
The DVS 204’s optional equipment includes:
• IR 901 remote control — Extron’s IR 901 (part #70-152-01) is an infrared
remote control which replicates all of the front panel controls of the
DVS 204 except the Menu and Next buttons.
• SDI input card — Serial digital interface (SDI) input can be added to the
DVS 204 model by the installation of an SDI input card (part #70-168-01).
• Rack shelf mounting kit — The 1U high, half rack width DVS 204 can be rack
mounted using the rack shelf mounting kit (part #60-190-01).
