1-1 Features

Chapter 1 Overview

The DNW-A25/A25P is a digital

portable editing recorder for the

Betacam SX format. It is equipped

with a color LCD monitor and speaker

to enable editing of news material in

the field.

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.

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

Combining two DNW-A25/A25P

units allows you to perform assemble

editing, insert editing, and audio split

editing. DMC (dynamic motion

control) is possible when both the

source and recording sides use the

Betacam SX format.

This unit can also be connected to a

BVE series or other editor for remote

editing.

Sequential recording

Combining two DNW-A25/A25P

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.

Features

1-2 Overview

Chapter 1 Overview

525 or 625 versatility

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.

Combination of two units

Using the BKNW-225 to combine two

DNW-A25/A25P units gives you a

portable editor.

Economical

• 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.

Compact and lightweight

Even though it is a standalone editing

recorder equipped with an LCD

monitor and a speaker, thanks to its

compact design and light weight, you

can carry it easily.

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

You can execute preread editing,

using video or audio signals recorded

on the tape as the edit source for insert

editing. Using this function, the

previously read signals ca be sent to

mixers for mixing and returned to the

original channels.

AC and DC power

This unit is equipped with V-shoe

attachment, on which BP-L60(A)/

L90(A) or BP-90(A) battery or an AC

adaptor can be mounted. The unit can

operate for about 80 minutes with BP-

L90 battery mounted. For AC

operation, you can connect an AC-

550/550CE or AC-DN2(A) adaptor.
