The MSW-M2100/M2100P is a digital videocassette
player based on the MPEG IMX format.
This unit uses large scale integrated circuits for signal
processing, and has a simple internal construction,
allowing it to provide functionality at least equivalent
to a conventional VTR in a compact (4U size),
lightweight, and low power consumption design.
It not only offers playback in MPEG IMX format, but
can also play back tapes recorded in Betacam SX
format, analog Betacam format, or digital Betacam
format.
MPEG IMX format
The MPEG IMX format uses the same 12.65-mm
width tape as the conventional Betacam series. This
economical format uses 50 Mbps high image quality
MPEG-2 compression, and offers up to three hours of
recording.
The video signal compression, as in the Betacam SX
format, uses MPEG-2, and compressed data can be
passed directly without loss of quality, not only to
VTRs, but also to other devices with MPEG support,
such as nonlinear editors or servers. There is thus high
compatibility with the next generation of digital
television formats supporting MPEG-2.
The audio tracks allow up to eight channels to be
recorded, and this also provides future extensibility for
multichannel, multilingual broadcasting, data
broadcasting, and so on.
High-performance heads and compatibility
playback function
The newly developed high-performance heads and
dynamic tracking (DT) technology provide high-
density playback in narrow tracks with high reliability.
In addition to the MPEG IMX playback heads, this
unit is also equipped with Betacam SX format
playback heads, and analog Betacam DT heads, to
provide compatibility playback functions, and
allowing a wide variety of recorded resources to be
used effectively.
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 signals for output,
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 output
• Analog audio signal output (4 channels)
• Serial Digital Interface SMPTE 259M output
(component digital video/audio, 8 channels)
• AES/EBU serial digital audio output (8 channels)
• SDTI-CP SMPTE 326M output (MPEG video/audio
data)
• Time code output
