6-5. File System

An innovative PC memory card allows users to store and recall
camera and system data including assignment control. Camera
parameters can be individually handled by storing a reference file
and scene file in a commercially available PC memory card.
Depending on the capacity of the memory card, a large number of
file groups (each containing up to five scene files and one reference
file) can be stored. Individual customization with this PC memory
card system enables special artistic camera settings to be stored and
recalled immediately.
Photo 6-2 PC Memory Card
The file system of BVP-900 Series cameras includes reference file,
scene file and lens file. The reference file stores the standard set-up
data in the auto set-up mode plus the standard setting of those switch
functions which are not executed with the auto set-up mode. The
scene file stores paint data for each scene, and up to five scene files
can be stored in the BVP-900 system. The lens file contains data to
compensate for various errors induced by the lens, and data on 15
types of standard lens is preset in the factory. (Up to 50 lens fits.)
The BVP-900 Series detects the type of lens and uses the appropriate
data automatically. If necessary, the lens data can be modified by
users.
The data to compensate for any errors induced by the CCD imager
and optical system, such as black shading, white shading, black set
and flare, is separately stored in the optical head block of the OHB-
750A/730 Series.
(a) File transfer capability
With the file transfer function, reference file and scene file data can
be transferred among multiple cameras, or between camera heads
and the MSU-700. In a multi-camera operation system, optimum
picture matching is simply and easily achieved by transferring the
appropriate camera setting data from the master camera to other
slave cameras via the CNU-700 or CNU-500. Thus, any camera can be
set to a uniform condition once a master camera is specifically
adjusted.
(b) PC memory card
The complete setting of a camera, including reference file and scene
files, can be stored in a small PCMCIA-standard PC memory card.
This unique memory card facility also stores information such as a
complex system configuration assigned from the MSU-700 via the
CNU-700/500. Memorized parameters can be accurately retrieved at
any time and from any camera.

6-6. Auto Set-up

BVP-900 and BVP-950 cameras incorporate a sophisticated Auto Set-
up 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.)

6-7. Control Priority and Parallel Mode

(a) 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-700 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-700 is in the panel active status, only the iris and
master black controls inoperative on the MSU-700 can be set by
pressing the lit IRIS/MB ACTIVE button.
(b) Parallel Mode
The MSU-700 and RCP-720/721/730/731/740/741 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-700 or RCP-700 Series control panel.

6-8. S-Bus Control

(a) 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 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 to a DVS-7000
