1360 x 765. Also offered are HDTV 480p,
720p, and 1080p output rates.
RGB signals are passed through. For
switches between sources, Triple-Action
Switching™ (RGB delay) eliminates visible
switching transitions to enhance the
professional look of presentations. Triple-
Action Switching blanks the screen when the
System 7SC switches to a new source.
A/V INPUTS AND OUTPUTS
The System 7SC provides a total of seven
inputs. It offers quad-standard video
decoding compatibility (NTSC 3.58, NTSC
4.43, PAL, and SECAM) as well as the
advantage of accepting interlaced or
progressive YUV signals, including HDTV
480p, 720p, and other such signals for up-
scaling. Using BNCs, six of the inputs are
configurable for composite video, S-video,
component video, or RGB. Located on the
front panel, the seventh input accepts
composite video on a RCA connector, S-
video on a 4-pin mini-DIN connector, or
computer-video on a 15-pin HD connector.
This makes it convenient to connect a laptop,
camera, or DVD player directly, without
accessing the back of the switcher. Also, the
System 7SC is able to control and accept
signals from a slaved switcher on input #1.
The output signal is simultaneously available
on a 15-pin HD connector and five BNCs. All
Switcher & Video Scaler Combination Provides
Convenient System Control of Presentations
E
xtron’s new System 7SC is a
seven input, dual output,
multi-format switcher with a
built-in video scaler.
The Extron System 7SC features projector
and room control along with RGB & video
integration capabilities ideal for rental,
staging, and permanent installations using
plasma displays as well as CRT, LCD, and DLP
projectors. This system switcher provides
video scaling, which uses Extron’s latest up-
conversion technologies with DMI (Dynamic
Motion Interpolation) to match the rates and
resolutions of video inputs to the higher
native resolution of today’s fixed matrix
displays. Projector and room control,
universal compatibility with displays, and
audio switching capabilities are also offered.
VIDEO SCALING AND SWITCHING
To optimize image quality as well as
maintain maximum image brightness and
detail, video inputs need to be scaled to
progressive scanning RGB resolutions that
match the “sweet spot” or native resolution
of the digital display being used. Using
advanced digital video scaling technologies,
the System 7SC scales any video input,
including any interlaced or progressive
YUV signal, to one of thirteen common
computer-video, progressive HDTV, or
plasma resolutions.
The System 7SC includes Extron’s newly
developed Dynamic Motion Interpolation
(DMI) scaling technology. DMI is an advanced
motion prediction and compensation method
used to deliver the best aspects of still and
motion algorithms. The DMI process results in
a new level of image enhancement capability
with no loss of image fidelity.
The System 7SC offers industry standard
computer-video output rates: 640 x 480, 800
x 600, 832 x 624, 1024 x 768, 1280 x 1024,
and 1360 x 1024. For plasma displays, the
System 7SC provides plasma output rates:
848 x 480, 852 x 480, 1280 x 768, and
RGB inputs are passed through, while all
video and progressive HDTV signals are
scaled.
For balanced/unbalanced stereo audio, the
System 7SC offers 3.5 mm captive screw
input and output connectors as well as audio
attenuation/gain adjustments for each input
provided. Audio breakaway is available
through RS-232 only. Audio breakaway
allows a user to switch audio from one input
source and video from a different input
source to the same output destination. It is
used when the audio and video sources
comprising a presentation are not generated
by the same source.
PROJECTOR, ROOM, AND SWITCHER
CONTROL
The System 7SC can be programmed for
projector control. Universal projector control
is possible through programming via
downloadable RS-232 or IR drivers, IR
learning capabilities, or user-defined RS-232
commands. The System 7SC offers two
methods for configuring the switcher for
projector control. Using the first method, the
System 7SC uses RS-232 or IR drivers,
including the downloadable, pre-configured
drivers similar to those designed for the
System 5
cr Plus. Using the second method,
the user determines which IR or RS-232
commands to associate with the user-
