1. INTRODUCTION
The ESI VLS-2000 extends the capabilities of high definition projectors, monitors, and other highresolution display devices. It provides the ability to view a wide range of video sources at the full
capabilities of the display. The VLS-2000 contains sophisticated video processing electronics, which will
de-interlace, re-scale, sharpen, and reformat as necessary to provide the clearest, smoothest viewing
regardless of the video source.
The VLS-2000 has a sophisticated set of features, which together allow any display system to operate with
multiple video sources, originating from DVD, Film, Video, or Still Cameras. The VLS-2000
automatically selects the proper enhancements to perform, optimizing the video stream to provide the best
possible viewing experience within the capabilities of the display system. Some of the features provided
are:
• Video De-interlacing – Conversion of slow, 30 frames per second image (Interlaced), to a fast 60
frames per second image (Progressive). This eliminates flickering and doubles the amount of
detail the eyes see each frame.
• Film Reconstruction – Studio conversion of Film to Video requires movies to be re-timed from 24
frames per second to 30 frames per second. The VLS-2000 analyses the video and recognizes the
source as film, which allows it to perfectly reconstruct the original film frames.
• Line Doubling, Tripling, Quadrupling, and Scaling – Regardless of the format of the display
device, the VLS-2000 allows conversion of the video source to a format which is optimized for the
display device. A video source with less video lines than the display can be expanded, with new
lines added, calculated from surrounding lines with algorithms that minimize annoying artifacts.
• Image Sharpening – Special filters use information from surrounding lines and other frames to
reconstruct the original image, regardless of the limitations of TV transmission and recording. All
the information present in the signal is extracted, and used to help sharpen the displayed image.
• Format Conversion – Regardless of whether the original source was a video camera (4:3 format)
or motion picture (16:9 format) , the picture will be converted to appear correctly on the display
system. A TV movie will show up centered in the middle of a movie screen, while a Hollywood
movie will appear in the shape that the director intended it to be watched.
• Picture Adjustment – Besides the standard Brightness, Contrast, Color, and Tint, the VLS-2000
allows black level, noise filtering, and detail to be adjusted on an input-by-input basis. These are
automatically saved and restored when that input is selected. This allows switching from DVD to
cable TV to any other source, without having to adjust the projector.

2. INSTALLATION AND SETUP
2.1 Connections
Figure 2 shows the rear panel layout of the VLS-2000. Input connections are grouped on the left
side of the panel. The Output connector is to the right of the Inputs, and the Power connection is
at the far right.

2.1.1 SVideo Input
Connect an S-Video source to this input, using a standard S-Video cable. If the source
equipment has both S-Video and Video connectors, S-Video is preferable to maintain
the highest possible video quality.
2.1.2 Video Input
Connect a composite video source to this input, using a video quality Phono style
cable. If the source equipment has both S-Video and Video connectors, S-Video is
preferable to maintain the highest possible video quality.
2.1.3 YCrCb Input
Connect a Component Video source to this input, using three video quality Phono
style cables. The video source should be labeled to match these three connectors. Do
not connect RGB video sources to this input. YCrCb provides the highest possible
video quality and should be used whenever the source equipment provides it.
2.1.4 HDTV Input
ESI VLS-2000 Video Line Scaler Operating Manual Page 5
Connect a direct video source to this input. This signal is a pass-thru when selected,
allowing high definition sources to be switched to the projector input. No processing
is performed on this input, so the format, whether YprPb, or RGB, should match the
requirements of the Display System. This will allow the use of high definition sources
which need no video processing. It also allows multiple VLS-2000 units to be chained
together to expand the number of available sources.
