The MSW-2000-series models are digital videocassette
recorders based on the MPEG IMX format.
Each 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 recording and 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 recording and playback in narrow tracks with
high reliability. In addition to the MPEG IMX
recording and playback heads, this unit is also
equipped with Betacam SX format playback heads,
digital Betacam playback heads, and analog Betacam
DT heads, to provide compatibility playback functions,
and allowing a wide variety of recorded resources to
be used effectively.
(Note that the compatibility playback functions differ
depending on the models covered by this manual.)
