Overview
The BKMW-E2000 is a network interface board for
installation in an MSW-2000 series digital
videocassette recorder. With this board installed, the
VTR can be added to a 10/100/1000Base-T network to
transfer video, audio, and metadata as MXF files. You
can use MFX data received over the network to change
VTR settings and to record video and audio to
cassettes. MFX (Material Exchange Format) is a file
format that stores video, audio, and metadata in a
single package. It enables communications between
network devices such as VTRs and servers.
E-VTR Functions
A VTR with this board installed (called an e-VTR
below) provides the following functions in addition to
functions provided by standard MSW-2000 series
VTR.
MXF file transfer and reception (file
management)
MXF files containing video, audio, and metadata can
be send and received over Ethernet networks (using
the FTP protocol).
Web server network services
Internet browsers such as Internet Explorer and
Netscape Navigator can be used for operations on files
in the e-VTR. Browsers can also be used to check and
change setup menu settings, start automatic
adjustments from the maintenance menu, and display
adjustment results.
Windows application network services
Installing e-VTR Manager, the supplied Windows
application, allows FTP file transfers and monitoring
of video and audio from the application.

E-monitor functions
Video and audio can be monitored on a computer
screen.
Video is sent from the e-VTR using JPEG
compression, and audio is sent using A-Law
compression.
Centralized network management by
SNMP (Simple Network Management
Protocol)
Thanks to MIB2 support, the network can be centrally
managed by an SNMP manager.
Mail notification of faults
Mail messages can be sent automatically to alert
system managers to errors and conditions such as drum
usage in excess of 1000 hours. Up to 5 recipients of
mail notification can be registered, and conditions for
mail notification can be set separately for each user.
Network transmission data rate limitations
Limitations can be placed on data transmission rates
for transmissions from the e-VTR to the network. This
can prevent congestion and severe degradation in
performance when the network is busy.
FTP transmissions by control panel
operations
You can start an FTP file transfer from any point on
the tape by operations on the VTR control panel, and
stop the FTP file transfer at any point.
File jump function
When the tape already contains data defined as MXF
files, you can jump between neighboring files and play
the files back.
