Overview
High-precision digital signal processing
and range of interfaces
The MPEG IMX VTR digital video signal processing
uses 4:2:2 component video signals complying with
ITU-R Rec 601/SMPTE 259M, which are compressed
with ISO/IEC 13818-2000 MPEG-2 compression.
While supporting a wide range of input and output
signals, all of the VTR internal processing is digital,
providing high stability and reliability.
The audio signals, similarly, are based on AES/EBU
format, and are subjected to digital signal processing
while still uncompressed.
The following interfaces are standard equipment, for
ease of connection to different external devices.
• Analog composite signal input/output
• Analog component signal input/output
• Analog audio signal input/output (4 channels)
• Serial Digital Interface SMPTE 259M input/output
(component digital video/audio, 8 channels)
• AES/EBU serial digital audio input/output (8
channels)
• SDTI-CP SMPTE 326M input/output (MPEG video/
audio data)
• Time code input/output
Network interface function (MSW-M2000E/
M2000EP only)
The MSW-M2000E/M2000EP is equipped with an
Ethernet
a)
connector, enabling the VTR to be added to
a 10/100/1000Base-T network to transfer video, audio,
and metadata as MXF files. You can use MXF data
received over the network to record video, audio, and
metadata onto cassettes. MXF (Material Exchange
Format) is a file format that stores video, audio, and
metadata in a single package. It enables
communication between network devices such as
VTRs and servers.

High image quality MPEG-2 intraframe
encoding at 50 Mbps
The video signal compression uses MPEG-2
intraframe encoding conforming to 4:2:2 Profile @
Main Level, with a 1:3.3 compression ratio; the data is
then recorded with a bit rate of 50 Mbps. With the
highly efficient MPEG-2 compression, the image
quality is high enough to withstand a range of editing
and dubbing operations.
The recorded MPEG-2 data can be passed directly to
other nonlinear systems, allowing optimum editing
with no loss of image quality.
High quality eight-channel audio
High quality 16 bit/48 kHz digital audio is supported.
There are eight digital audio input/output channels, and
four analog audio input/output channels.
To support even higher quality recording and
playback, there is a four-channel mode using 24 bit/48
kHz encoding. Thus this unit is eminently suitable not
only for multichannel applications, but also for high
quality audio editing.
Recording and playback of SDTI
compressed data
This unit is fitted with SDTI-CP input/output
complying with SMPTE 326M, and can therefore be
used for transferring MPEG-2 data, audio data,
metadata, and so on to a VTR or nonlinear device.
Newly developed multifunction control
panel
While a compact 4U size, this unit has a front panel
which provides a wide range of functions while
maintaining existing operability.
