Introduction

Chapter 1 Overview 1-7
Features of the DVS-7300/7350
I/O Expansion System
The DVS-7300/7350 I/O expansion system comprises a DVS-7300/7350
system centered on a DVS-7000A, in combination with a DVS-V6464M or
HDS-X3600 Digital Video Routing Switcher. The primary inputs, signal
matrix, and so on of the DVS-7000A are replaced by the DVS-V6464M or
HDS-X3600, thus increasing the number of inputs and outputs.
Features
Support for large-scale live systems
Wide range of inputs and outputs
This system supports a wide range of inputs and outputs, including 60
primary inputs, 28 auxiliary outputs, and five assignable outputs. It is ideal
for use in a large outside broadcast vans and large live productions using
substantial numbers of cameras, VTR materials, and monitor feeds.
Source assignment at the video and key levels
The source assignment to cross-point button selections introduces the concept
of video level and key level; by means of a virtual level of key source
assignment to buttons, more efficient source assignment is possible. The
AUTO SELECT function (linking the video source and key source) also
follows these settings.
Full range of preview functions (AUTO PVW2, SHOW KEY)
When an M/E PVW (mix/effect preview) or PST (preset) is selected on the
EDIT PVW (edit preview) bus, an automatic output switch to the M/E PGM
or M/E PVW signal can be made according to the on-air status of the M/E or
crosspoint selections on the PGM and PST buses (AUTO PVW2). Also, with
a simple button operation the key source selected on an M/E keyer can be
output to EDIT PVW (SHOW KEY function).
Full-featured video effects
M/E banks
There are three M/E banks, each with equivalent functionality. Each bank
includes two keyers which can be operated independently and
simultaneously.
The output from any M/E bank can be input as a background signal to any
other, for further keying and other operations.

1-8 Chapter 1 Overview
PGM/PST bank (operation coupled to a DMK-7000)
In a DVS-7350 I/O expansion system, the three M/E banks are supplemented
by a PGM/PST bank, for manipulating the final program output from the
switcher. Using the PGM/PST bank, you can insert a total of four
downstream keys into the final background output. These operations are
controlled from the switcher control panel, but the processing is carried out
by a DMK-7000 Digital Multi Keyer connected to the system.
In a DVS-7300 I/O expansion system, by connecting a DMK-7000, and
equipping the control panel with a BKDS-7032 DSK Control Panel Unit, you
can again control the insertion of a maximum of four downstream keys.
In this case, the four downstream keyers are equipped with the same
functions, including key source selection, video and key source linking, key
memory, as the M/E keyers. Even though a separate unit, there is integral
operation with the switcher.
DME wipes (operation coupled to a DME)
By connecting a DME-7000 or other Digital Multi Effects unit, you can use
the control panel to carry out DME wipes, using DME effects (the “DME
LINK™” function).
System configuration flexibility
Wide range of options
In addition to the two basic control panel types, that is, 3.5-M/E and 3-M/E
panels, there is a wide range of options, allowing just the features required to
be installed in a system.
Support for D1 and D2 formats
Except for some options, both D1 (component) and D2 (composite) signal
formats are supported. A simple control panel operation switches between
the D1 and D2 selections, and also in the case of D1 format between 525- and
625-line systems.
Convenient interfaces with external equipment
Using the DVS-7300/7350 I/O expansion system along with the DVS-
V6464M Routing Switcher via the BKDS-7700 Tally Interface Unit, you can
make up a large-scale switcher system.
Connecting the BVE-9100 Editing Control Unit to your system will allow
you to carry out such advanced editing operations as ISR (Intelligent Status
Reporting) system and EDL (Edit Decision List ) management.
Features of the DVS-7300/7350 I/O Expansion System

Chapter 1 Overview 1-9
The system is provided with VTR control for controlling external devices
such as VTRs, and a PERIPHERAL II timeline.
Powerful remote control functions
You can connect the BKDS-2010 Control Panel to the DVS-7000A and use it
as a separate panel exclusively for the M/E banks.
For key adjustment operations such as chroma key adjustment, the BKDS-
7060 Keyer Remote Control Panel is available.You can use the dedicated
panel connected to the DVS-7000A to remote-control the auxiliary bus and
Shot Box operations.
Operation adapted to live operation
The DVS-7300/7350 I/O expansion system control panel is designed to
provide the necessary rapid operability for the live broadcast environment.
Combined use of menu settings and button operation
All detailed settings for video processing are carried out in menus, but for
some more frequently used operations you can carry out the selections and
adjustments by direct button operations on the control panel. In particular,
clip, gain, density and other basic parameter settings can be controlled using
the three knobs provided on each M/E bank, quite independently of the
currently accessed menu.
Snapshot function
The DVS-7300/7350 I/O expansion system has a comprehensive snapshot
function, which allows a collection of settings for a particular effect to be
saved in memory, and recalled as required for an instant return to the settings.
Snapshots can be saved from memory to floppy disk, and reloaded into the
system when required.
Snapshots can reflect the overall system settings, or can apply only to key,
wipe, or DME wipe settings for a particular M/E bank. These latter can be
easily saved and recalled using the buttons of the FlexiPad™ provided on the
M/E bank.

1-10 Chapter 1 Overview
Role of the DVS-V6464M or HDS-X3600 as an I/O
Expansion Unit
In this system, the DVS-V6464M or HDS-X3600 is included as a part of the
switcher system, providing the primary inputs, cross-point switching, source
selecting when the DMK-7000 is connected, and auxiliary bus expansion
functions. Thus the DVS-V6464M or HDS-X3600 serves as a dedicated unit
for expanding the inputs and outputs. It cannot also be used for its standard
function as a routing switcher. In particular, the S-BUS interface is dedicated
as the interface to the DVS-7000A. If you attempt to use an S-BUS interface
to another routing switcher system, this system will no longer operate
correctly.
Input and Output Signals to the DVS-7300/7350 I/O
Expansion System
The principal input/output signal names and the devices and connector names
are shown in the following table.
The signal names and connector names correspond one-to-one. For example, the signal name
“Primary input 1” corresponds to the connector named “INPUT 1.”
For other inputs and outputs, refer to the Operation Manual for the relevant device.
Signal names Device Connector names
Primary inputs 1 to 60 DVS-V6464M or HDS-X3600 INPUT 1 to 60
Auxiliary outputs 1 to 8 DVS-7000A AUX BUS OUTPUT 1 to 8
Auxiliary outputs 9 to 28 DVS-V6464M or HDS-X3600 OUTPUT 45 to 64
Assignable outputs 1 to 5 DVS-7000A AUX BUS OUTPUT 9 to 13
