The HDW-M2100/M2100P is a high-definition (HD)
digital videocassette player based on the HDCAM
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.
In addition to HDCAM format playback, the unit can
also play back tapes recorded in the Digital Betacam,
MPEG IMX, Betacam SX, and analog Betacam
formats.
HDCAM format
The HDCAM format uses the same 12.65-mm width
tape as the conventional Betacam series. It provides
high definition images, offering up to two hours of
recording. For video signal compression, prefiltration
and coefficient recording technologies are used.
High-performance heads and compatibility
playback functions
The newly developed high-performance heads and
dynamic tracking (DT) technology provide high-
density playback in narrow tracks with high reliability.
In addition to HDCAM playback heads, the unit is
equipped with Betacam SX playback heads and analog
Betacam DT heads, for playback compatibility with
existing recording formats. The VTR automatically
detects the recording format of tapes when they are
loaded, so that no menu settings need to be made when
changing formats.
High-precision digital signal processing
and range of interfaces
The digital signal processing uses HD 4:2:2
component video signals complying with SMPTE
292M, which are converted into parallel data and then
compressed into HDCAM format.
The audio signals are based on AES/EBU format, and
are subjected to digital signal processing without being
compressed.
The unit is equipped with a high definition to standard
definition (HD to SD) downward converter, and has
the following interfaces as standard equipment, for
ease of connection to different external devices.
• SD analog composite signal output
• SD analog component signal output
• Analog audio signal input/output (4 channels)
• HDSDI SMPTE 292M input/output (HD digital
video/audio, 4 channels)
• SDI SMPTE 259M output (component digital video/
audio, 4 channels)
• AES/EBU serial digital audio input/output (4
channels)
• SDTI SMPTE 305M input/output (HDCAM video/
audio data) (option)
• Time code input/output
• CUE audio output
High quality four-channel audio
High quality 20 bit/48 kHz AES/EBU digital audio is
supported. There are four digital audio input/output
channels, and four analog audio input/output channels.
Playback of SDTI compressed data
(optional)
This unit can be fitted with SDTI input/output
complying with SMPTE 305M, and can therefore be
used for transferring HDCAM data, audio data,
metadata, and so on to a VTR or nonlinear device via
an SDTI interface.
Multifunction control panel
While built in a compact 4U size, this unit has a front
panel which provides a wide range of functions while
maintaining existing operability.
