Chapter 1 Overview
The DNW-A28/A28P is a digital portable
videocassette recorder for the Betacam SX format.
The features of this unit include the following.
Betacam SX format
This unit supports the Betacam SX format, developed
by Sony as the digital version of the Betacam SP
format. No format conversion is needed for use with
nonlinear editing systems and server systems.
Playback compatibility with Betacam SP
It can play tapes recorded in the Betacam and Betacam
SP formats, allowing you to make effective use of
Betacam and Betacam SP cassettes recorded in the
past. You can assemble news gathering systems that
combine this unit with conventional Betacam SP
camcorders.
Sequential recording
Connecting two DNW-A28/A28P units allows you to
perform sequential recording from one unit to another.
When you perform overwrite recording using only two
cassettes, the last two hours recording can be obtained
at any time. When you renew the cassette about every
1 hour, endless recording is possible.
Good Shot marks/Shot Data
During tape rewinds, this unit reads the REC Start
(RS) and Good Shot (GS) marks recorded by Betacam
SX camcorders, and builds an index. The index
facilitates quick cue-ups of desired marks (index
search function), for greater editing efficiency.
When shot marks are recorded on the tape, you can
display and sort lists of the shot marks.
Preread editing
Chapter 1Overview
Digital signal processing
This unit processes 4:2:2 component digital signals in
the D-1 format.
Inter-frame data compression
Inter-frame data compression by MPEG2 4:2:2 Profile
@ Main Level (1 GOP = 2 frames) reduces the volume
of data to about
1
/10.
Rich variety of input and output signals
The following input and output signals are supported.
• SDI (serial digital interface) video and audio
• Analog composite video
• Analog audio
• Timecode
Powerful editing functions
You can use video or audio signals recorded on the
tape as the edit source for insert editing because this
unit uses the preread heads to read the signals in
advance. This type of editing is called “preread
editing”.
Back space editing
To record multiple scenes as a single sequence, you
can use the PAUSE button to record the scenes
continuously with no noise or breakup between scenes.
AC and DC power
The BP-L60(A)/L90(A) or BP-90(A) battery or an AC
adaptor can be used on this unit. The unit can operate
for about 80 minutes with a BP-L90 battery mounted.
For AC operation, you can connect an AC-550/550CE
or AC-DN2A adaptor.
To mount a battery or the AC-DN2A on this unit,
attach the optional BKP-L551 Battery Adaptor.
By connecting two DNW-A28/A28P units to a BVEseries or other editor, you can perform assemble
editing, insert editing, and audio split editing. When
both the source and recording sides use the Betacam
SX format, you can perform DMC editing.
You can also perform editing by connecting this unit to
a VTR such as the DNW-A100/A75 series.
Chapter 1 Overview1-1
Features
525 or 625 versatility
Chapter 1 Overview
When using the Betacam SX format, 525 or 625 mode
recording and playback can be selected from a menu.
When using the Betacam and Betacam SP formats,
only simple viewing is possible for tapes recorded in
different mode.
Other
•Betacam SP cassettes and inexpensive UVW
cassettes can be used in addition to Betacam SX
cassettes.
•Special high-durability heads and components
contribute to reduced maintenance costs.
•You can stack up to three DNW-A28/A28P units for
use in recording and editing.

2-3 Handling Cassettes
To record with this unit, you can use half-inch width
Betacam SX S cassettes, Betacam SP S cassettes
(metal tape), or UVW S cassettes (metal tape).
The number in the model name of the cassette
indicates the cassette’s normal recording time in
minutes (for example, 12 minutes in the case of the
BCT-12SX). However, when you are using Betacam
SP S cassettes and S cassettes for UVW VTRs on this
unit, you can record up to twice the amount of time
indicated on the cassette (see the table below).
Usable Cassettes
Betacam SX
Betacam SP (metal tape)
UVW (metal tape)
Notes
•Digital Betacam cassettes cannot be used.
•Oxide tapes recorded in the Betacam format and
metal tapes recorded in the Betacam SP format can
be only played back.
2 Load a cassette in the direction shown in the figure
after checking the following points.
•That “ERROR-10” is not displayed in the FL
display panel.
•That there is no slack in the tape.
If “ERROR-10” appears in the FL display panel
This means that there is condensation inside the unit.
For the steps to take in this case, see “Moisture
Condensation”(page A-3).
If there is slack in the tape
Take up the slack by rotating the reels in the directions
shown by the arrows in the figure, keeping one reel
fixed by pressing it with your finger as you rotate the
other reel.
The reels stop rotating when there is no more slack.

2-4 Setting Reference Video Signals
This section explains how reference video signals for
synchronization of video output and servo lock are
selected according to settings made with this unit.
Reference video signal for video output
Output video signals are synchronized with the signal
generated by this unit’s internal reference video signal
generator. The internal reference video signal
generator can be synchronized with an external
reference video signal or with an input video signal
(SDI or composite video).

Servo lock can be synchronized with an external
reference video signal, with an input video signal (SDI
or composite video), or with the signal generated by
this unit’s internal reference video signal generator.
As shown in the table below, a signal for
synchronization of the internal reference video signal
generator and a reference video signal for
synchronization of servo lock are selected according to
the setting of setup menu item 309, the setting of the
OUT REF in the submenu, and the operating mode of
the unit.

Reference video signals in editing
When the OUT REF is set to REF, the signal shown in
the table below is selected, depending on whether
setup menu item 309 is set to AUTO1 or AUTO2.
Note
Normally select AUTO1 and synchronize the external
reference video signal with the input video signal.
Select AUTO2 when the external reference video
signal is not synchronized with the input video signal.

submenu (see page 2-17).
If you select AUTO1 under these conditions, noise
may enter the video and audio signals, making editing
difficult.

Setting Reference Video Signals
When the signal selected in the menu is not being input
The servo reference video signal and internal reference
signal generator synchronize as follows.
When “Input” is selected for the sync signal
Chapter 2 Preparations
(see note d) of the table on previous page)
When a video signal is not being input, synchronize
with an external reference video signal.
When “Ref” is selected for the sync signal
(see note c) of the table on previous page)
When an external reference video signal is not being
input, there is no external synchronization. The servo
reference video signal synchronizes with the output of
the internal reference video signal generator.
