■ Vertical (flicker) filtering – The VSC 900 and 900D have four

vertical (flicker) filter settings selectable through the front panel

LCD navigation menus. Vertical (flicker) filtering provides line

averaging so that before the scan converter eliminates lines in the

down conversion process, it fills in missing information. By filling

in averaged information, the scan converter helps to maintain

vertical detail and eliminate picture flicker.

■ Freeze button – The input of the VSC 900 and VSC 900D can be

frozen using the freeze button on the front panel or RS-232. This

feature allows the scan converter to capture a frame of video to

display for an extended period of time, even after the source has

been removed.

■ Genlock – A necessary feature for broadcast or production

environments, genlocking is the process of synchronizing all video

devices for the purpose of pixel switching and chroma keying of

computer overlays. A specific type of genlocking, known as

chroma lock, refers to the synchronization of the sync signals and

chroma. This allows the signals to be edited and composed to

make a complete segment without any kind of distortion, glitch,

or signal irregularity.

■ Internal test pattern generator – The VSC 900 and VSC 900D

offer four test patterns for quick and easy monitor set-up:

Color Bars, 32x32 crosshatch, 4x4 crosshatch, and gray scale.

■ RS-232/RS-422 remote control – A rear panel RS-232/RS-422

control port provides easy operation of the VSC 900 scan

converters utilizing Extron’s Simple Instruction Set (SIS™) of basic

ASCII code.

■ Downloadable firmware – Updated firmware can be

conveniently downloaded from the Extron Web site. Changes to

features and capabilities can be easily upgraded through the

RS-232/RS-422 port.

■ Executive Mode – Ideal for unsecured environments, executive

mode enables the user to lock out all front panel functions except

for centering controls; all other functions remain active through

RS-232/RS-422.

■ Flexible mounting options – The VSC 900 models are housed in

1U high, half rack width metal enclosures that can be mounted

under or through a desk or in a rack.

■ International internal power supply – The 100-240VAC,

50/60 Hz, auto-switchable, internal power supply provides

worldwide power compatibility.

■ VSC Remote – The included Extron VSC Remote provides infrared

remote control for the VSC scan converters. It performs most

front panel functions such as image freeze, zoom in and out, size

and shift both horizontally and vertically, adjust the vertical filters,

and set presets.

The Extron

VSC 900 and VSC 900D two input high-resolution,

computer-to-video scan converters combine superior processing with

an advanced feature set, including both BNC RGB and 15-pin HD

inputs with loop-through outputs for easy integration. In addition, the

VSC 900D offers an SDI digital output.

The VSC 900 and VSC 900D accept computer images at resolutions up

to 1600 x 1200 and output a scan converted signal as composite

video, S-video, component video, and/or RGB video. Both models are

designed to be integrated into high-end broadcast facilities and other

demanding production, training and presentation environments as they

offer exceptional output quality, the ability to genlock to an external

blackburst signal and optional SDI output. Other applications include

videoconferencing, video recording, and viewing images on an NTSC

or PAL monitor or other display device.

■ Autoscanning – Automatically recognizes and converts the

incoming computer image, up to 1600 x 1200 resolution,

100 kHz horizontal, and 120 Hz vertical scan rates.

■ Integration-friendly inputs – Input one is on female BNC

connectors, eliminating the need for adapter cables and offering

the proven reliability of BNC connections. A second input is

offered on a 15-pin HD female VGA connector. Adapters are

available for MAC inputs.

■ Buffered loop-throughs – Provides for local monitor outputs on

both BNC connectors and a 15-pin HD female VGA connector,

enabling a signal to be easily monitored or distributed without

using a distribution amplifier.

■ Auto–Image

™

setup – A press of a button automatically adjusts

the sizing, centering, and filtering to optimize the output image.

This can save an enormous amount of time and effort in fine-

tuning displayed images.

■ Three simultaneous outputs – NTSC or PAL video is output as

RGBHV, RGBS, RGsB, or component video, S-video, and

composite video.

■ Optional SDI output (VSC 900D only) – A digital 4:2:2 output is

available for incorporating digital video devices into environments

such as video production studios, non-linear editing suites,

staging events, and video broadcast studios.

■ Chroma attenuation – Chroma attenuation is an ideal feature for

broadcast environments where colors in logos and images must

be set at 75% saturation for transmission. The VSC 900 and VSC

900D have the ability to attenuate an input signal down to the

correct output level, eliminating the need to recreate the image

and/or content.

■ Input memory presets – Allow the scan converter to

automatically recall up to 16 user presets, 60 factory presets, and

eight zoom presets, accessible via RS-232 or the included IR

remote. Each memory location stores filter, size, centering, and/or

zoom settings for a source that can be instantaneously recalled

during a presentation.

■ High quality zooming and panning – The VSC 900 models

feature variable zoom up to 200% and allow panning across the

screen. User-friendly positioning, including centering and sizing,

is accessible through the front panel for quick and efficient image

setup.

■ Horizontal filtering – There are eight horizontal filters selectable

through the front panel LCD navigation menus to enhance and

stabilize the final scan rate converted video image. Horizontal

filtering prevents anti-aliasing or pixel elimination so that less

detail is dropped when the television scans from left to right.
