1-1 Features

The DVW-250/250P is a portable videocassette

recorder in the Digital Betacam series. It allows

recording and playback of sound and picture in the

Digital Betacam format.

color playback signal is available at 24 times normal

speed, making tape cuing both fast and accurate.

Two LCD units for ease of operation

The front panel includes two LCDs: the smaller shows

the unit status and time indications, and the larger

displays the audio level meters, the video level meters,

or the setup menu.

1-1-1 Features of the DVW-250/

250P

By switching the display mode, it is possible to change

the audio level indications for fine adjustment in a

narrower range.

The following are some of the features of the DVW-

250/250P.

Backlighting is provided to make the displays easier to

read in gloomy conditions.

Flexible input/output interfaces

The unit is designed to accept either analog video

(component/composite) and audio signals, or D1

format serial digital video/audio signals. It is therefore

highly suitable for use not only in analog systems but

also in all-digital systems.

Analog input signals pass through the built-in A/D

converter, and are converted to 10-bit digital video

signals and 20-bit digital audio signals. Similarly,

both digital and analog output signals are provided, for

flexible support of mixed analog-digital systems.

1-1-2 Digital Betacam Format

Overview

The Digital Betacam format is based on the

conventional Betacam and Betacam SP formats, and

allows high-performance digital recording and

playback.

One of the features of the Digital Betacam format is

the introduction of a new technique known as

“coefficient recording,” which allows the data rate of

the video signal to be reduced to approximately half.

This makes 120 minutes or more of recording possible

with an “L” size cassette.

The compressed video signal includes error-correcting

codes (ECC), which correct the signal on playback.

This powerful error-correcting system provides the

improved signal reliability which is another feature of

the Digital Betacam format.

Simple system configuration using the serial

digital interface

The serial digital inputs to the SDI (Serial Digital

Interface) connector provide for one video signal and

four audio channels through a single BNC connector.

When connected to other digital equipment, this makes

setting up and transporting, for example on outside

assignments, extremely straightforward.

High quality digital recording

This unit records both sound and vision on the tape in

the Digital Betacam format (see the figure at the end of

this page). Since all internal processing is digital,

signal outputs are stable, and reproduction is very

accurate.

Recording format

The processing of the Digital Betacam video signal

conforms to the D1 4:2:2 component digital format,

with digitization according to ITU-R BT. 601.

The following figure shows schematically the Digital

Betacam recording format on the tape. A set of six

diagonal tracks contains one field of video and four

channels of audio information.

Designed for field operations

The unit is compact and lightweight (main unit

approximately 6.6 kg or 14 lb 8 oz), making it ideal for

carrying and operating in the field. The power

consumption while recording is about 26 W (with the

MODE switch in the SAVE position and the CONFI

switch in the OFF position), and the optional battery

pack provides about two hours of continuous

recording.

Notes on operation and storage

Cleaning the video heads

Protect the unit from violent shocks

It is possible to damage the internal circuitry and

mechanism or spoil the external finish.

Use the Sony BCT-5CLN or BCT-D12CL Cleaning

Cassette for cleaning the audio and video heads.

Follow the instructions with the cleaning cassette.

After use

Turn the power switch off.

Related manuals

In addition to this Operation Manual, the following

manuals are available.

When not using the unit for a long period

Remove the cassette and batteries.

These should be consulted as necessary.

• Maintenance Manual Part 1 (supplied)

Describes the maintenance of this unit.

• Maintenance Manual Part 2 (option)

Contains circuit diagrams and adjustment procedures

required for the maintenance of this unit.

Operating and storage locations

Store the unit in a level place which is well ventilated.

Avoid operation or storage in the following locations:

• In extremely hot or extremely cold conditions

• In extremely dusty conditions

• In very high humidity

• Where the unit will be subjected to severe vibration

• Close to strong magnetic fields

• Exposed to direct sunlight for long periods, or close

to heating equipment

Condensation

If you move the unit suddenly from a cold place to a

warm place, or use it in a very humid location,

condensation may form on the head drum. If the unit

is operated in this state, the tape may adhere to the

drum, and cause a failure or even permanent damage.

Take the following steps to prevent this from

happening:

• Remove the cassette before operating the unit in

conditions where condensation is likely to form.

• If the HUMID indication is showing, condensation is

present: wait until the HUMID indication disappears,

and then insert a cassette.

• Do not load a cassette on which condensation has

formed into the unit.

Selecting the monitoring mode for recording

Opening the lid covering the time code setting controls

Use the CONFI switch on the connector panel to select

the monitored signal.

• To monitor the simultaneous playback of the

recorded video and audio signals from the confidence

heads, using a video monitor or other equipment

connected to the VIDEO OUT connector, set the

CONFI switch to the ON position.

• To carry out error detection by means of ECC

without direct monitoring of the recorded signals, set

the CONFI switch to the ECC position. In this case

the monitor output during recording is an E-E signal.

• To carry out no direct monitoring of the recorded

signals, and only RF envelope monitoring, set the

CONFI switch to the OFF position.

Setting a constant user bit value

The user bit values recorded on the time code track

provide for eight hexadecimal digits, which can be

used to hold the date, time, scene number or other

information.

• The OFF setting results in the lowest power

consumption, and the ON setting the highest. When

using the unit with a battery pack, set the CONFI

switch to the ECC or OFF position.

6 Set the F-RUN/R-RUN switch to F-RUN or R-

RUN.

1 Set the VITC switches in the time code setting

controls to select the lines in which the VITC is

inserted.

F-RUN (free-run): The time code advances

continuously, regardless of the operating state

of the unit. When you select this position, the

time code starts advancing immediately.

R-RUN (record-run): The time code advances

only during recording. When you select this

position, the time code starts advancing only

when you start recording.

Insert the tip of a fine screwdriver into the arrow-

shaped slot to turn the switch to the required

hexadecimal digit (see table on next page).

You can select the two lines where the time code is

to be inserted with the A and B switches.

With the R-RUN selection, the “REC RUN”

setting in the <SYSTEM 2> menu (see page 6-

4) determines whether the time code recorded

on the tape is taken from the time code

generator or continues from the value

previously recorded on the tape.

Time codes and battery pack replacement

This unit has an internal battery which provides a

battery lasts for about five years.

1) Drop frame mode

2) Non-drop frame mode

In the NTSC system, the actual frame rate is 29.97

frames per second. There is therefore a cumulative

discrepancy between the actual frame rate and the 30

frames per second rate on which time code is based.

Drop frame operation refers to the technique of skipping

frame numbers at appropriate intervals, to keep the time

code values in step with actual elapsed time.

Non-drop frame time code operation means that the

discrepancy between actual elapsed time and 30 frames

per second time code values is not corrected.

User Bits” (page 5-5).

Notes

• Switch positions 0 and 1 are not effective for the

DVW-250P (PAL).

• Switch positions B to F are not effective for the

DVW-250 (NTSC).

• Select lines for the VITC which are not occupied

by VITS (Vertical Interval Test Signal) or VIRS

(Vertical Interval Reference Signal).

• It is not possible to use line 11 (NTSC) or 8

(PAL) because these carry the reference

subcarrier signal.

2 Set the VITC REC switch to ON.

The VITC will be recorded on the tape with the

video signals. Note that LTC is always recorded.

• Once the unit is locked to an external time code, color

framing is disabled. To apply the color frame lock,

first switch the F-RUN/R-RUN switch to R-RUN,

then return it to the F-RUN position.

4-1-7 Locking the Time Code

Generator to an External Signal

It is possible to lock this unit to an external time code

generator, or alternatively to lock an external device to

the time code generator in this unit.

For an explanation of the color frame lock, see the

footnote on page 2-4.

Locking this unit to an external time code

Locking the user bit value to an external

signal

1 Turn the POWER switch off.

First lock the unit to an external time code source, then

set the EXT-LOCK/U-BIT switch to ON. This locks

the user bit values on this unit to the user bit values

included in the external time code.

2 Connect the time code output from the external

device to the TC IN connector of this unit, and the

video output to the VIDEO IN connector.

When the EXT-LOCK/U-BIT switch is set to OFF, the

user bit values are not affected by the external signal.

See the connections for the first DVW-250/250P in

the figure “Example connections for time code

locking” (page 4-12).

Settings for the output from the TC OUT

Connector

3 Set the F-RUN/R-RUN switch on this unit to F-

RUN.

The following setup menu items affect the output from

the TC OUT connector.

This locks the time code generator in this unit to

the external time code signal.

Once the time code generator has been locked, the

time code continues in sync even if the signal is

disconnected from the TC IN connector. In this

case the accuracy of time code synchronization is

determined by the accuracy of the generator of the

sync signal for the input video signal. If the signal

is then disconnected from the VIDEO IN

connector, the accuracy is that of the internal time

code generator.

For details of setup menu operations, see Section 6-3 “Setup

Menu Settings,” <SYSTEM 2> menu (page 6-4).

“TC OUT” item

This selects either of the following as the output from

the TC OUT connector:

GEN: the signal output by the time code generator

AUTO: the signal output by the time code generator

during recording or in E-E mode, and the LTC

signal from the tape during playback

Notes on external locking of the time code

generator

• The effect of carrying out steps 2 and 3 of the above

procedure with the POWER switch on and a cassette

loaded depends on the setting of the MODE switch,

as follows:

“TC DELAY” item

This selects the LTC phase correction for the output

from the TC OUT connector as follows:

OFF: the signal selected by the “TC OUT” item

without correction

AUTO: the LTC signal adjusted to correspond to the

video output

SAVE: The external lock applies when the tape

transport is stopped, recording is paused, and

during recording.

PB/EE or PB: The external lock applies only during

recording. To apply the external lock at other

times, either carry out step 1 above, or press the

REC button, putting the unit into E-E mode.
