Introduction
About the ViewMAX
The ViewMAX series of Video Down Converters are designed for video and image processing professionals who
require the highest quality output images, high reliability, and control over all aspects of the scan conversion process.
ViewMAX receives high-resolution video in analog RGB format from sources such as computer workstations, medical
imaging equipment, or HDTV video systems. A push-button termination switch allows the input video to be terminated
by the ViewMAX converter or passed via loop-through connectors to other devices. ViewMAX automatically locks to
video sources with horizontal scan rates up to 105 KHz and supports conversion of both interlaced and non-
interlaced input videos. Proprietary digital signal processing techniques are used to process the video in real time to
derive broadcast-quality NTSC or PAL video output. Composite, S-Video (Y/C), Betacam (R-Y, Y, B-Y), and RGB
output formats are also supported. All outputs may be genlocked to support studio applications.
Folsom Research’s proprietary Adaptive Flicker Filter technology allows for seven combinations of output filtering
producing a crisp output picture.
An optional D1 output module is available (standard on the ViewMAX/Pro) to support output of digital video in serial
format.
A DVI digital interface input module is available (ViewMAX/DVI and ViewMAX/Pro) to allow digital video sources
processing. This module also includes a buffered DVI loop-through feature.
The Advanced Options module available on the ViewMAX/Pro provides for Genlock loop-through BNC connections
and Background Mixing to Y/C, YUV, RGB, RGBS, Composite video, and D1 sources. This module also includes the
D1 output feature described above.
ViewMAX allows the user to control all aspects of the video conversion process via user-friendly front panel menus or
remotely through the RS-232 and RS-485 interfaces. Examples of the type of control provided include:
•continuous horizontal and vertical pan
•zoom in and out
•adjustable for flicker reduction
•adjustable under scan
•edge adjustments
•brightness, contrast, hue, and saturation adjustments
•test patterns
•freeze frame
•set NTSC or PAL output video standard
•set RGB or YUV output color space formats
•set output sync on green
The unit can store at least 32 user-specified configurations of pan, zoom, underscan, and output aspect ratio in non-
volatile memory for subsequent recall. The first four configurations are available for recall using convenient front
panel hot keys.
Input and output settings are maintained in nonvolatile memory and are automatically restored on power up. The
video “footprints” for over 40 interlaced and non-interlaced formats are stored in the video configuration library. Edge
adjustments for each “footprint” are automatically recalled the next time that video source is identified.
The front panel includes ten hot keys, a control knob, and a bright vacuum fluorescent display that provides a wide
viewing angle. The front panel hot keys give the user direct access to picture adjustment settings, pan, zoom, and
test pattern menus. The graphical display also provides features including slide bars, scroll bars, and highlighting
menu display selections. The menu system also remembers the last selection to quickly access commonly used
menu functions. Fine adjustments are facilitated by the smart control knob, which allows for coarse to fine
adjustments by the rate of knob movement.
Attention to the Installation and Operation Sections of the manual is important to ensure trouble-free operation.
Should you have any questions regarding the operation of this unit, please consult the factory.

Technical Description
The ViewMAX Video Down Converter from Folsom Research, Inc. converts high-resolution video from computer
workstations to standard RS-170A RGB/NTSC or CCIR RGB/PAL formats in real time. S-video (Y/C) and Betacam
(YUV) output formats are provided. Digital video output (serial D1) is offered as an option. Digital Visual Interface
(DVI) with loop-through is also offered as an option. Background mixing allows the input computer video to be
displayed over a background video similar to picture-in-picture and also supports chroma keying to allow features
requiring two video sources (for example, a weather man superimposed on a satellite image). After conversion by
ViewMAX, images can be stored, recorded, and displayed on standard video devices, including video projectors,
video tape recorders, and monitors. ViewMAX video output can also be Genlocked to an external source to allow
connection to broadcast or video editing systems.
The analog RGB input signal can be interlaced or non-interlaced. After being filtered to prevent aliasing, the input
signal is digitized. ViewMAX has a triple 8-bit analog-to-digital converter, one for each (RGB) video input channel.
The sampling frequency of the converters is set to digitize the input at 140MHz, which produces a horizontally scaled
720-pixel image. The 8-bit color conversion process minimizes losses in color fidelity.
Vertical scaling is performed via a weighted interpolation algorithm, which has been designed to preserve the spatial
quality of the original image without line dropout. The horizontally scaled image is transferred internal memory stored
in YCbCr 4:2:2 format. The vertical scaling occurs after the image is retrieved back from internal memory. The
resultant digital image is converted to analog RGB format with three 8-bit digital-to-analog converters. A digital
encoder is used to provide broadcast-quality NTSC or PAL output.
Control is provided by a user-friendly front panel or remotely via an RS-232 serial interface or an RS-485
multidropped serial interface.
