VIDEO SCALERS
DVS 204
Four Input Digital Video Scaler
of still and motion algorithms. This process results in a superior level of
image enhancement capability with no loss of image fidelity.
Accu-RATE Frame Lock (AFL) — 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.
Scaled output resolutions — The DVS 204 provides 36 user-selectable
computer-video output rates, up to 1400 x 1050 and including 480p, 720p,
1080p, and 1080i.
Aspect ratio conversion — Ability to horizontally and vertically size any
video input to meet a specific aspect ratio. Three memory presets for aspect
ratio are available for each input by pushing each input button repeatedly.
Quad-standard video decoding compatibility — The DVS 204 uses a
digital, four-line adaptive comb filter to decode NTSC 3.58, NTSC 4.43,
PAL, and SECAM for integration in systems worldwide.

DESCRIPTION
Extron DVS 204 scalers incorporate the latest in high performance and
proprietary scaling technology with the input flexibility essential for today’s top-
notch audio/video applications—including an optional Serial Digital Interface
(SDI) input. With 36 selectable output rates, including a variety of HDTV
rates, the DVS 204 is the perfect scaling solution for A/V environments such as
boardrooms, conference rooms, and home theaters, as well as rental and staging
applications. Models with 12V external power supplies are ideal for yachts,
planes, or other environments using a 12V power source.

SDI input card — An optional Serial Digital Interface (SDI) input is
available.
Picture controls — Brightness, contrast, color, tint, horizontal and vertical
sizing, and horizontal and vertical centering are provided.
Vertical blanking — Variable top and bottom vertical blanking eliminates
edge noise caused by tapehead switching and captioning.
Front panel security lockout — This feature locks out all front panel
functions except for input selection; all functions, however, remain active
through RS-232 control.
RS-232 control — A rear panel, RS-232 control port provides connection of
the DVS 204 to a third-party control system.
Display compatibility — The DVS 204 scalers are compatible with display
devices such as VGA/SVGA monitors, HDTV, LCD, DLP™, D-ILA®/LCoS,
or plasma.
Simple Instruction Set (SIS) — Extron SIS is a set of basic ASCII code
commands that provides simple control through a third-party control system.
Instead of programming in long, obscure strings of code, SIS makes it easy to
operate an Extron product using RS-232 control.
There are four models in the DVS 204 line—DVS 204, DVS 204D,
DVS 204 12V, and DVS 204D 12V. Each model supports the following video
formats on one of four inputs: RGB pass-through, component, S-video, and
composite video. Input 4 also accepts RGB computer-video as a pass-through
signal. The “D” (digital) versions also support SDI signals. For all models, RGB
or component video is output simultaneously on one female 15-pin HD
connector and six female BNCs.

To enable superior scaling performance, the DVS 204 features several Extron
proprietary technologies: Dynamic Motion Interpolation (DMI™), 3:2 and 2:2
pulldown detection (patent pending), True Rate, and patented Accu-RATE
Frame Lock (AFL™). Key features include aspect ratio control to accommodate
different movie formats, three aspect ratio presets per input, and vertical
blanking adjustments.
•
The DVS 204 can be controlled using the front panel or through the RS-232
serial port. Each model can also be controlled remotely through the optional
IR 901 remote. The front panel buttons control video input selection and
picture adjustments. All functions are available through RS-232 using Extron’s
user-friendly Simple Instruction Set (SIS™).

•
Rack-mountable — The DVS 204 is housed in a 1U, half rack width metal
enclosure.
Power supply — The DVS 204 is available in versions suitable for fixed or
mobile applications. The DVS 204 and DVS 204 D are equipped with an
internal, autoswitching power supply for worldwide compatibility. For marine
and other mobile applications, a 12 VDC, 3A power supply is supplied with
the DVS 204 12V and DVS 204 D 12V.
FEATURES
•
Input and Pass-through connectors — Input one accepts composite video
on one female BNC; input two accepts composite, S-video, or component on
three females BNCs; input three accepts S-video on a 4-pin mini DIN; input
four accepts an RGB computer-video pass-through or 15 kHz RGBS, or
RGBcvS signals on a female 15-pin HD connector. The optional SDI card
can be configured for any of the four inputs.
