1-1 Features

Chapter 1 Overview

The DNW-A75/A75P is a digital videocassette recorder, based on the Betacam SX format. This unit not only offers digital recording and playback, but can also play back tapes recorded in the conventional analog Betacam format. The following are some of the features of the system.

Betacam SX format

The Betacam SX format was developed as a digital version of the Betacam SP format, and is a digital VTR format supporting nonlinear editing systems and server systems. Compared with analog Betacam, the Betacam SX format reduces the tape speed to approximately one-half. The drum rotates at 75 revolutions per second, recording two frames of video data and four channels of digital audio in ten diagonal tracks. The longitudinal control and time code tracks are the same as in the analog Betacam format.

Tape transport direction

Auxiliary track

High image quality, high audio quality, high reliability

Chapter 1 Overview

Even with a low data rate, recording and playback with high image quality and high audio quality is achieved. The unit also has a powerful error-correcting system.

Data compression by interframe encoding

This is the first VTR to perform data compression by MPEG-2 interframe encoding conforming to 4:2:2 Profile @ Main level. The data rate is reduced by a factor of 10.

Playback compatibility with Betacam/ Betacam SP

This unit can play tapes recorded in Betacam/Betacam SP format. This makes for efficient use of existing material in Betacam/Betacam SP format.

Chapter 1 Overview

Powerful editing functions

With two of these units together, you can carry out automatic or manual editing, using either assemble or insert editing. The system also provides a powerful range of functions for setting and amending edit points, preview, review, and other aspects of efficient editing.

DMC (dynamic motion control) editing

You can save a varying speed, in the range -1 to +2 times normal speed, for an editing segment, and automatically edit with this varying speed.

Split editing

In insert editing, this allows the audio IN and OUT points to be set independently.

Preread editing

The audio or video on the tape can be read out, processed, and rerecorded with no time shift, using the preread heads.

Cross-fade editing

For audio editing, you can select from cut-in editing, fade-in editing, and fade-in/fade-out editing.

Menu-based setup

Initial settings for the unit’s operating condition, the interfaces with connected equipment, and so forth can be made by menu operations on the front panel of the unit.

Wide range of indications

In addition to the LED display which shows the operating status and current settings of this unit and connected equipment, a fluorescent display displays numerical values including time code, user bits, editing IN and OUT points, editing durations, error messages and setup menu information.

Selection of external/internal time code

You can record using either an external time code or the output of the built-in time code generator. You can also synchronize the built-in time code generator to an external time code.

Connection to external control devices

It is possible to connect a BVE-900/910/2000/9000/ 9000P/9100/9100P or other BVE-series editor, a control and monitoring computer, a BVR-50/50P remote controller for the built-in digital video processor, and so forth.

Economy

•You can use a variety of tapes, including low-priced tapes for UVW-series VTRs and tapes for Betacam SP or Betacam SX format. Using large cassettes, recording of 180 minutes or more is possible.

•The design needs minimal maintenance, and requires no daily maintenance or checks. The drum and other components have reduced maintenance costs.

6 Audio signal selection buttons

The function of these buttons depends on the setting of the audio selection function selector switch as follows.

When the MIXING indicator is lit

To select which input channel is to be recorded on

Chapter 2 Location and Function of Parts

which channel, press one of the buttons (CH-1 to CH-

4) in the EXT row while holding down one of the buttons (CH-1 to CH-4) in the REC CH row. For example, if you press the CH-2 button in the EXT row while pressing the CH-1 button in the REC CH row, signals from input channel 2 are recorded on channel 1. If you press two buttons in the EXT row simultaneously, signals from the corresponding two channels are mixed and recorded on the same channel.

Note

Before selecting signals from two input channels for recording in one recorder channel, check to be sure that the emphasis settings (ON or OFF) of the two input channels are the same. Recording and playback of mixed signals cannot be carried out correctly if the emphasis settings are different. You can check the settings in the channel display section of the level meters. [EMPH] is displayed for channels with the emphasis setting on.

There is therefore a cumulative discrepancy between the actual frame rate and the 30 frames per second rate on which time code is based. In drop-frame mode, except once every 10 minutes, the first two frames are skipped at the beginning of each minute to keep the time code values in step with actual elapsed time.

In non-drop-frame mode, the correction is not carried out, and there is a discrepancy of about 86 seconds per day between actual elapsed time and time code values.
