Extron electronic DVS 204 - Manual (Page 2)

■
Accu-RATE Frame Lock (AFL ™ ) – A 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 outputs – The DVS 204 offers 33 different output rates.
(see list in specifications).
■
Aspect ratio conversion with memory presets – Ability to
horizontally and vertically size any video input to meet a specific
aspect ratio. Three aspect ratio memories for each input can be
recalled by pushing the 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.
■
SDI input card – Optional SDI Serial Digital Interface input
available.
■
Picture controls – Brightness, contrast, color, tint, horizontal and
vertical sizing, and horizontal and vertical centering are available
per input for fine picture adjustments.
■
Vertical blanking – Variable top and bottom vertical blanking
eliminates edge noise caused by tapehead switching and
captioning.
■
Executive mode – The DVS 204 features a reduced function
mode that locks out all front panel functions except for input
selection. All functions, however, remain active through RS-232.
■
RS-232 control – A rear panel, RS-232 control port provides
integration of the DVS 204 into third-party control systems.
■
Display compatibility – Extron DVS 204 scalers are compatible
with display devices such as VGA/SXGA monitors, HDTV devices,
LCDs, DLPs, or plasma displays.
■
Simple Instruction Set (SIS ™ ) – Extron’s SIS is a set of basic
ASCII code commands that provide 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.
■
Power supply – 12V models ship with an external power supply;
the other two models include a 100-240VAC, 50/60 Hz,
autoswitchable internal international power supply for worldwide
power compatibility.
There are two models in the DVS 204 line: the DVS 204 and the
DVS 204 D. Each model supports the following video formats on one
of four inputs: an RGB pass-through, component, S-video, and
composite video. The “D” (digital) version also supports SDI input
signals. For all models, RGB or component video is output
simultaneously on one female 15-pin HD connector and three female
BNCs. Each model also has the option of an internal, international
power supply or a 12V, external power supplies.
To enable superior scaling performance, the DVS 204 features several
of Extron’s latest proprietary technologies: Dynamic Motion
Interpolation (DMI
™ ), 3:2 and 2:2 pulldown detection (patent
pending) True Rate ™ recovery, and patented Accu-RATE Frame Lock ™ .
Key features include aspect ratio control to accommodate different
movie formats, memory recall for up to three presets per input, and
vertical blanking adjustments. With 33 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,
and other environments using a 12V power source.
The DVS 204 digital video scaler is housed in a rack mountable,
1U high, half rack width metal enclosure. Control of this scaler is
provided via the front panel and RS-232 control. The DVS 204 scaler
can also be controlled remotely through an optional IR 901 remote.
The front panel buttons control video input selection and picture
adjustments. All functions are available through RS-232 utilizing
Extron’s user-friendly Simple Instruction Set (SIS
™ ).
■
Input and pass-through connectors – Input one accepts
composite video on one female BNC; input two accepts
composite, S-video, or component on three female BNCs; input
three accepts S-video on a 4-pin mini DIN; input four accepts an
RGB pass-through or RGBcvS signal on female 15-pin HD. The
optional SDI card can be configured for any of the four inputs.
■
3:2 and 2:2 pulldown with True Rate recovery ™ detection
(Patent Pending) –
3:2 pulldown detection for NTSC and 2:2 film detection for PAL
is an advanced film mode processing technique. It helps
maximize image detail and sharpness for NTSC or PAL sources
that originated from film. When such materials are detected, this
technology applies video processing algorithms that optimize the
conversion of film-based video, resulting in richly detailed images
with sharply defined lines.
■
True Rate ™ recovery– Recovers the natural motion dynamics of
material that originated from film.
■
Dynamic Motion Interpolation (DMI ™ ) – DMI technology is an
advanced motion detection and compensation method used to
deliver the best aspects of still and motion algorithms. This
process results in a superior level of image enhancement
capability with no loss of image fidelity.
