1-1 Features

Chapter 1 Overview

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.

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

The following are some of the features of the DVW250/250P.

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.

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.

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.

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. By switching the display mode, it is possible to change the audio level indications for fine adjustment in a narrower range. Backlighting is provided to make the displays easier to read in gloomy conditions.

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.

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.

•Maintenance Manual Part 2 (option) Contains circuit diagrams and adjustment procedures required for the maintenance of this unit.

Chapter 1 Overview

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.

Time codes and battery pack replacement

This unit has an internal battery which provides a backup power supply to the time code generator. The time code generator can, therefore continuing running while you change the battery pack. The backup battery lasts for about five years.

1) 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.

2) Non-drop frame mode

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.

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.

•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.

For an explanation of the color frame lock, see the footnote on page 2-4.

Locking this unit to an external time code

1 Turn the POWER switch off. 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.

See the connections for the first DVW-250/250P in the figure “Example connections for time code locking” (page 4-12).

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

RUN.

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.

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: 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.

Locking the user bit value to an external signal

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. When the EXT-LOCK/U-BIT switch is set to OFF, the user bit values are not affected by the external signal.

Settings for the output from the TC OUT Connector

The following setup menu items affect the output from the TC OUT connector.

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

“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
