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:

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

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

Extended Technical Access to Camera Video
Processing
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

programmed and logical access to dozens of
technical adjustments. Perhaps no other system can

control system, multiple MSUs can be used to remotely
control/supervise a single studio from different
operational engineering and control rooms.
