APPLICATIONS
FEATURES
Extron’s SVS 100 is a four input, one output, video switcher that
improves presentation quality by providing seamless vertical
interval switching without the need to genlock the sources.
Applications such as videoconferencing, distance learning, video
editing, and staging benefit from the cost-effective SVS 100, which
makes glitch-free switches without using expensive genlocking
equipment. By eliminating loss of sync during switching and by
color matching inputs, the SVS 100 enhances the professional
look of your presentations. Without color correction, the appearance
of specific colors can differ dramatically from source to source.
Individual settings required by each input source are also saved
for consistent color, tint, brightness, and contrast levels, ensuring
that colors match between multiple sources. Video images are
routed from sources such as VCRs, DVD players, scan converted
PCs, laserdisc players, videoconferencing CODECs, or document
cameras. For routing audio associated with any video input, the
SVS 100 features a four input, one output stereo audio switcher
with audio attenuation/gain.
■ Inputs – Accepts up to four NTSC or PAL video inputs. Two
inputs can be composite video or S-video, and two inputs are
composite video only. Each input also offers a loop-out for a
preview monitor.
The SVS 100 is compatible with NTSC or PAL signals and offers
composite and S-video inputs. Each input also offers a loop-out
for a local monitor. Three outputs are available simultaneously as
two composite video outputs and one S-video output. For switching
between inputs, the SVS 100 provides a seamless “cut” and a variety
of “wipe,” “dissolve,” and “fade” effects. The 24 digital transition
effects include left to right, right to left, top to bottom, and so forth.
Each effect has a user-adjustable duration ranging up to five seconds.
Color, tint, contrast, and brightness controls are provided per
input for color correction of each source signal. The SVS 100
provides up to 128 user preset memories, which saves color
adjustment settings for use with matrix switchers. Extron’s easyto-use Simple Instruction Set (SIS™) is provided to call up any
preset via RS-232 control. Unlike typical strings of lengthy,
tedious RS-232 programming code, SIS commands are
convenient and easy to enter. The use of the SVS 100’s presets
ensures consistent color, tint, brightness, and contrast levels
across all sources.
For system integration, the SVS 100 may be controlled through
RS- 232 control via Extron’s Windows®-based control program
or third-party control. Extron’s Simple Instruction Set™ is available
for calling up presets as well as all other functions of the SVS 100.
RS-422 control is also available.
■ Outputs – Three outputs provided simultaneously: two
composite video outputs on BNCs and one S-video output
on a 4-pin mini-DIN connector.
■ Seamless switching – A seamless “cut” reduces the amount of
noise caused by switching glitches. This noise reduction
reduces the load on a videoconference encoder, resulting in
better, transmitted video quality.
■ Digital effects – “Wipe,” “dissolve,” and “fade” effects are
provided to enhance the professional look of presentations.
“Wipe” effects may be hard “wipes” with clearly defined
edges or soft “wipes” with indistinct edges. 24 types of
transitions are available: left to right, right to left, top to
bottom, and so forth. Each effect provides a user-adjustable
duration ranging up to five seconds.
■ Picture controls – For color correction, the SVS 100 allows a
user to adjust the color, tint, brightness, and contrast of each
video input.
■ Blanking controls – Extron’s exclusive variable vertical
blanking adjustments allow a user to mask noise that
occasionally appears at the top and bottom of a processed
image or to crop unneeded portions of an image.
■ Audio switching – Features an internal, 4x1, balanced or
unbalanced stereo audio switcher on 3.5 mm conductor
terminals for selecting the desired audio of any video input.
Audio gain/attenuation is available.
■ User presets – Provides 128 user presets for saving color
adjustment settings per video input. Using presets, the SVS 100
ensures consistent color, tint, brightness, and contrast levels
across all sources.
■ Genlock – Features the ability to genlock to an external black
burst signal for use in broadcast or live environments that
require genlock.
■ RS-232/422 remote control – Extron’s Simple Instruction
Set™ is provided for RS-232 control via third-party control
or Extron’s Windows®-based control program. RS-422
control is also available.
■ Executive mode – Locks out picture controls, audio controls,
and genlock; all other functions remain active through
RS-232/422.
■ Power supply – Includes a worldwide, 100-240VAC,
50/60 Hz, auto-switchable internal power supply.
■ Rack-mountable – Housed in a 1U, one rack width, metal
enclosure.
Typical Genlock Application Without the SVS 100
This application diagram depicts a typical application with the necessary genlocking equipment to provide a seamless switch. Sources
include a video camera, document camera, scan converted PC, and VCR. Each source signal and the SW 6 AV MX switcher are genlocked
using multiple time base correctors (TBCs) and a black burst generator. The SW 6 AV MX then routes the selected signal to the output.

Videoconferencing Application Using Four Sources
For videoconferencing applications with up to four sources, the SVS 100 may be used to save color correction presets for all
inputs. The SVS 100’s seamless switching capability helps avoid dropped calls that can result from loss of sync with some
videoconferencing systems. In the application diagram below, the SVS 100 switches a video camera, scan converted PC,
document camera, or VCR to its composite video and S-video outputs for the projector, videoconferencing CODEC, and
recording VCR.

Videoconferencing Application Using a Matrix Switcher and Multiple Sources
For videoconferencing applications using multiple sources via a matrix switcher, the SVS 100 may be used to save color correction
presets for up to 128 matrix switcher inputs. When each matrix switcher input is switched to the SVS 100, its preset may be
recalled via RS-232 control prior to the SVS 100’s switch, ensuring consistent color, tint, brightness, and contrast levels across
all sources. In the application diagram below, Extron’s Matrix 50 matrix switcher routes a video camera, document camera, scan
converted PC, and DVD player to two composite video inputs on the SVS 100. The SVS 100 switches its inputs to the S-video
output for the videoconferencing CODEC.

Staging Application
For staging applications using multiple sources via a matrix switcher, the SVS 100 may be used to save color correction presets
for up to 128 matrix switcher inputs. When each matrix switcher input is switched to the SVS 100, its preset may be recalled
via RS-232 control prior to the SVS 100’s switch, ensuring consistent color, tint, brightness, and contrast levels across all
sources. The SVS 100’s switch can then be made using a seamless cut or one of 24 digital switching effects. In the application
diagram, Extron’s Matrix 50 matrix switcher routes multiple DVD players and Betacam cameras to two S-video video inputs
on the SVS 100. The SVS 100 switches its inputs to the S-video output for the DVS 150 scaler. The DVS 150 scales its input
up to 1024 x 768 and sends the RGBHV signal to the large-venue projector for display.
