4-5. Auto Set-up
The HDC-900 and HDC-950/930 cameras incorporate
a sophisticated Auto Setup system to adjust the video
processing circuitry parameters for optimum color
matching. In addition to auto white balance, auto black
balance and auto level set-up, the following
parameters can also be adjusted according to a
reference file.
Auto white shading (The shading compensation is
achieved with horizontal and vertical sawtooth and
parabolic waveform as well as with a digitally
synthesized waveform for almost 1000 individual
correction zones created by DSP.)
Skin detail auto hue (automatic hue detection for
specified color range, with full skin detail function.)
4-6. Control Priority and Parallel Mode
Control Priority
When a camera system is configured using the CNU-
700 or CNU-500, each camera can be connected in
parallel to both an RCP-700 Series Remote Control
Panel and the MSU-700A/750 Master Setup Unit, and
is controlled from whichever unit has control priority.
Priority for iris/master black adjustments only can be
obtained when the IRIS/MB ACTIVE button on the
panel on which the PANEL ACTIVE button is not lit.
When the MSU-700A/750 is in the panel active status,
only the iris and master black controls are inoperative
on the MSU-700A/750 and can be set by pressing the
lit IRIS/MB ACTIVE button.
Parallel Mode
The MSU-700A/750 and RCP-700 Series panels have
a PARA button to select Parallel Mode. When the PARA
button of the unit is pressed and lit, Parallel Mode is
activated and all the control functions, other than the
iris/master black controls, become operative from both
units. The Parallel Mode can be canceled by pressing
the PARA button of the MSU-700A/750 or RCP-700
Series control panel.
4-7. S-BUS Control
The S-Bus Concept
A further advantage of the Sony camera control system
is the 'S-Bus control' technique, which is based on an
original Sony concept. Studio installations and OB
units use digital routers as the nerve center for a
complete audio/video system. With Sony system
integration, all the equipment is connected to the Sony
digital router via a LAN, called the 'S-Bus'. With the S-
Bus system, control and tally signals are interlocked so
that they, along with video and audio signals, can be
simultaneously switched from a central terminal. Each
input/output source can be given a name, which can
then be displayed on the source name display panel of
a DVS-7000/8000 Series Video Switcher or on the BKS-
R3280/R3281 Status Character Display. One example
of the operational advantages of the S-Bus system is
that the routing of input signals to the primary inputs -
of a DVS-7000/8000 Series Video Switcher can be
changed at any time without having to re-connect
cables. Even the source name display, tally signal and
tally display are interlocked and changed
automatically.

Controlling the router from an MSU panel
The digital router's cross point can switched from the
MSU-700A/750 by pressing its camera select button.
SDI video monitoring is enabled.
