4-1. Sony Camera Command Network System
Several decades of TV operations have led to the
development of many alternative operational and
engineering philosophies relating to the deployment of
video and technical control and to the monitoring and
routine maintenance of multi-camera studio and OB
truck installations. Sony has re-examined the entire
studio camera architecture with the goal of structuring
a far higher degree of system flexibility. This new
architecture is based on:
• High-speed communication of digital control
commands
• A considerably augmented Master Set-up Unit, the
MSU-700A/750
• The introduction of a powerful technical 'nerve
center' concept - the camera Command Network
Units, CNU-700 and CNU-500
• Electronically assignable camera remote control
panels for use with these camera command network
units
4-2. Master Set-up Unit – MSU-700A/750
The Master Set-up Unit (MSU) is the centralized
technical control position for multi-camera systems.
The MSU-700A/750 has been designed to provide
comprehensive and wide ranging technical
supervision and alignment of a complex camera
system from a single centralized panel. If it is desirable
in a large program origination complex to extend this
supervision to more than one control location (for
example, separate operational and engineering/
maintenance control centers) then a number of MSU-
700A/750 units can access the entire camera system.
To exercise maximum flexibility in controlling a multi-
camera system, the MSU-700A/750 is designed to
work in conjunction with the CNU-700 and CNU-500
Command Network Units. However, if a simplified
system is desired, the MSU-700A/750 can also
operate as a stand-alone unit. It provides rapid, finger-
tip access to all controls relating to the smooth
functioning of an operational system, including:
• Technical alignment controls for the entire camera
chain
• Picture and waveform monitor switching
• System configuration
• Control data filing
Extended Technical Access to Camera Video
Processing
A traditional high-end studio/OB camera chain entails
a multiplicity of technical adjustments. In combination
they optimize of the technical alignment of the RGB
video processing channels and allow a broad degree
of control over certain critical video subsystems (such
as image enhancement, color reproduction, dynamic
range, etc.). Typically, these technical controls are
segregated into those requiring regular operational
access - and are provided as remote adjustments on
video operational panels or technical control panels -
and others, perhaps requiring less frequent access,
which are relegated to screwdriver adjustments on
various circuit boards within the camera head and
HDCU. This separation often entailed a degree of
protracted (and frustrating) re-alignment when subtle
creative readjustments are desired for a particular
picture composition.
In the HDC-900 Series camera system, Sony has
adopted the philosophy that all technical controls are
important and that remote access to virtually all
controls on a single control panel would bring higher
operational efficiency. This led to the introduction of
the MSU-700A/750 Master Set-up Unit. To avoid undue
complication of the ergonomics of the panel layout that
would result from such extensive access, a novel
Electro Luminescent (EL) sub-panel forms an integral
part of the overall MSU-700A/750 control panel - Photo
4-1. This menu-driven touch screen allows remote pre-
programmed and logical access to dozens of
technical adjustments. Perhaps no other system can
better illustrate the enhanced degree of centralized
control than that relating to access to the many
adjustments required for the image enhancement
system. Depending upon the creative desires of the
program director, the MSU-700A/750 allows highly
flexible, finger-tip access to all critical adjustments,
including skin detail control.
The main features of the MSU-700A/750 are given
below.
(1) Easy operation
• Frequently used functions are directly accessed from
the panel.
• The following modes can be easily accessed by
using the new EL touch panel display for
maintenance and daily operation.
• Paint mode: Various paint items such as White,
Black and Flare are adjustable
• File mode: Storing, retrieving and transferring
reference files, lens files and scene files between
camera heads on a PC memory card
• Maintenance mode: System phase control, HDCU
video level alignment, selection of character display
from a CNU-700 and CNU-500, etc.
• Configuration mode: Entire control system
configuration, RCP assignment, etc.
• Card mode: PC memory card initialize, store to PC
memory card/recall from PC memory card, etc.
• Multi-mode: Setting of multi-camera operation such
as 'All', 'Control Priority', 'Parallel Mode', etc.
(2) Multi-MSU operation
In a conventional system, a single MSU controls a
single studio or multiple studios. However, in this new
control system, multiple MSUs can be used to remotely
control/supervise a single studio from different
operational engineering and control rooms.
(3) Standard switch
Users standard setting data is easily recalled by
pressing the 'standard' switch.
