Declass Review by NGA.
1. INTRODUCTION. This document presents requirements for the design,
assembly, installation and operation of equipment to produce high
quality photographs from various types of video tapes.
2. CONCEPT. Several techniques are used to convert television imagery
to photographic prints. These techniques vary widely in cost and
quality and many of the systems are not compatible. Video tape widths
which vary from ,1 inch to 2 inches and scan lines which range from
405 to 819 are two of the main problem areas. A system of integrated
commercial components must be devised to accept tapes from the most
common U. S. and European systems, display their contents at normal
speeds or in stop motion at the highest possible quality consistent
with the recording medium, and produce instant, high-quality, still
photographs of selected scenes.
3. ADMINISTRATION.
3.1. Evaluation of proposals will be based on cost, quality of
imagery, indications of commitment to fulfill these objectives,
and the experience and ability evidenced by inclusion of relevent
specifics.
3.2. Proposals should contain an indication of thorough comprehension
of the areas of prime concern, suggested solutions to problem areas,
and a schedule of major steps in the development process.
4. REQUIREMENTS.
4.1. General Configuration.
4.1.1. Playback. The basic component for this system will
be a standard, commercial, transverse scan, video tape
recorder. This equipment must utilize switching and/or plug-in
modules to accept tape with the following standards; 525 scan
line/50 field, 625/50, 405/50, and 819 scan line/50 field.
The system must be compatible with "Intervision" as well as
U. S. "high band" and "low band" broadcast systems. It also
must have the quality of a color system, but does not need to
have a full color capability. However, it must be designed to
accept available commercial equipment for modification so that
color capability can be achieved with minimum effort and
expense.

4.1.2. Stop-Motion. A disk-type video recorder will be
operated on line with the basic video recorder to provide
it with a capability for temporary storage and selected
stop motion or single frame display. Provisions must be
made to accept signals from either helical scan or trans-
verse scan recorders for a better quality stop motion
capability. The system must be able to advance the
recorded display frame-by-frame and to select and hold a
particular frame to recorded imagery. A small monitor
affixed to the disk recorder will display the imagery being
stepped or held. Off-the-shelf equipment may be modified
to suit this requirement.
4.1.3. Dis la . A Kinescope-type, flat-faced cathode ray
tube (CRT will be used to present imagery to be photographed.
This CRT will be large enough to present a 3x4-inch display
for reproduction. The display-recorder circuitry must
include contrast, brightness, etc., controls.
4.1.4. Photography. A 4x5-inch, high-speed, frame camera
will be used to photograph the quality CRT image. This
camera will be set and rigidly attached in such a manner
that full scale photographs (1:1) of the flat CRT can be
produced. A fine focus control will be included so that
the sharpest possible image can be obtained on the ground
glass. A between the lens shutter with a "Time" setting
and an adjustable exposure range from 1 second to 1/50th
of a second will be adequate. There will be no need
for an automatic exposure device, an exposure meter
attachment will be sufficient. The camera will have a
back that will accept cut film and "film packs" for use in
producing optimum photographic records. The back will
have provisions to accept a rapid, self-processing adapter
for use in producing urgently needed photos without the need
of a photographic laboratory.
4.1.5. Integration. All components must be interfaced
for optimum performance. Equipment must be positioned
and arranged for optimum man/machine operation and
maintenance. Controls must be adequately marked and
easily available, but must be positioned so as not to
interfere with the operator.
4.2. Additional Equipment Considerations.
4.2.1. Proposals should provide for and discuss capabilities
and limitations of the following types of electronic image
manipulation devices and techniques.

(a) "Spot Wobble" circuitry and controls for
decreasing scan line patterns of CRT's.
(b) "Vertical Aperture Equalizing" for apparent
increase in vertical resolution of imagery.
(c) "Gamma" or "Black Stretch" controls.
(d) "Exponential" or "White Stretch" controls.
(e) Edge enhancement or outlining techniques.
(f) Electronic magnification controls.
(g) Other circuitry or technqiues to help produce
and improved photographic still copy of video taped
material.
4.2.2. Considerations must be given for reducing Radio
Frequency Emissions in accordance with Federal Std. #222.
This specification is to be limited to information carrying
emissions.
5. PHYSICAL AND OPERATIONAL CONSIDERATIONS.
5.1. This equipment will be operated in a clean office type
environment. Special considerations must be given to reduce
heat output and noise emanating from the system.
5.2. The following facilities will be available as requested:
5.2.1. Electricity: 11OV, 1 phase and 208V, 3 phase,
4 wire.
5.2.2. Chilled water and tap water.
5.2.3. Compressed air at 80 psi.
5.2.4. Vacuum
6. DETAILED REQUIREMENTS.
6.1. The maximum size of any single component is not to exceed
32" wide x 65" long x 71" high, and will not exceed 1600 pounds
weight.
6.2. Environmental conditions within the room will be held to
temperatures of 72 degrees F.+5 degrees F. and humidities of
55% + 15% - 5%.
6.3. Provisions must be made for maximum personnel protection
from safety hazards that may be generated by the equipment.

6.4. The contractor is to assume responsibility for all facility
hook-up from the point where the facilities may enter the room.
6.5. If any component of this system is vibration sensitive so
as to adversely affect performance, adequate vibration isolation
must be incorporated in the design.
7. MAINTENANCE AND TRAINING.
7.1. A listing and price quotation of recommended spare parts
and test equipment will be provided as deliverable items
under the contract.
7.2. Written instructions for recommended testing procedures
must be included, as well as wiring diagrams and schematics.
7.3. It is highly desirable that initial utilization and operational
evaluation of this system not be hampered by less than optimum
operation of the equipment itself. However, the equipment embodies
several concepts whose technical details are not familiar to
most user personnel. Therefore, proposals must include a separate
price quotation for provision by the contractor for a technician
to help assure the proper and effective operation of the equipment
during its introductory phase. This technician must have been
acquainted with the development and assembly of the system and
must be proficient in the operation and repair of the system
components. During the crucial period of initial operation, he
must keep the equipment constantly tuned to optimum performance
and perform minor modifications, on the spot, as necessary. The
technician provided should be available for one year. During
that time, he will be expected to train customer maintenance
personnel to assume his duties.
7.4. Proposals must include installation specifications, including
estimates of necessary supporting services and equipment, such
as floor space, atmospheric environment and power.
7.5. The contractor must provide monthly progress report,
including currently updated schedules for delivery and installation
in accordance with specification No. DB-1001 (attached).
