High Picture Quality of MPEG2 4:2:2P@ML
The DNW-A22 Digital Video Cassette Player delivers the
superb digital picture quality of the Betacam SX format,
recording 8-bit, 4:2:2 component digital signals using an
advanced compression algorithm.
The robust compression algorithm of the Betacam SX format
results in a reduced bit rate of 18Mbps for the video signal,
achieving greater efficiency in transmitting the signal from the
field to the station and in storage onto disk.
Betacam SX picture quality exceeds that of Betacam SP
format, maintaining broadcast-quality pictures with excellent
luminance detail and improved color resolution. The
Betacam SX recording format also preserves 507 active
lines per frame as well as vertical blanking signal
information and supports 4-channel,
16-bit/48kHz digital audio.
Analog Playback Capability
The DNW-A22 has the capability to play back analog
Betacam and Betacam SP recordings made on oxide or
metal particle tape. This analog playback capability
maintains the long-term value of existing analog tape
archives and enables existing Betacam SP camcorders to
be used for acquisition.
Long Playing Time
Both S-size cassettes and L-size cassettes can be used
with the DNW-A22. A single S-cassette provides up to 62
minutes of playback time while an L-cassette provides up to
194 minutes.
Simple, User-friendly Operation
The DNW-A22 provides simple operation from the control panel,
with a familiar Jog/Shuttle dial to give editors a "hands-on" feel.
The Sony Betacam SX
TM
System achieves superior picture quality, faster editing, increased system
flexibility, and greater productivity in every aspect of news gathering and production compared to
conventional analog systems.
The Betacam SX format is the next generation Betacam
®
format, drawing on the long experience of
Sony in serving the ever-changing, real-world needs of the broadcast community. Complying with a
compression algorithm of MPEG2 4:2:2 Profile at Main Level (MPEG2 4:2:2P@ML), the Betacam SX
system brings all the way benefits of digital technology to the broadcast industry.
The DNW-A22 Digital Video Cassette Player is especially designed for easy integration into current
analog Betacam systems, providing the superb picture quality and cost-efficiency of the
Betacam SX format. Furthermore, the DNW-A22 has the capability to play back tapes recorded in the
current analog Betacam and Betacam SP
®
formats, which yields a logical, cost-efficient migration path
towards a totally digital environment.
Features
DNW-A22 Front Panel

High-speed Picture Search
High-speed picture search is available in shuttle mode at up
to 50 times normal play speed in both forward and reverse
directions.
Audio Monitoring
A matrix of push buttons is provided on the front panel for
switching the channel of audio monitoring. Each of the four
playback channels can be switched to either the left or right
monitor outputs.
525/60 or 625/50 Versatility
Composite output of the DNW-A22 is switchable from
525/60 to 625/50. When playing back Betacam SX tape, the
DNW-A22 operates in 625/50 mode without an external
adaptor. This flexibility enables the DNW-A22 to perform in
international environments.
Adjustment Free Operation
The DNW-A22 incorporates an Automatic Alignment System
to maximize the accurate reproduction of digital data. An
Automatic RF Equalizer optimizes the gain and phase of off-
tape RF signals. These automatic systems minimize the
need for time-consuming manual equalization and servo
system adjustments, which can lower maintenance costs.
Easy Maintenance
A self-diagnostic system advises of malfunctions within the
player. The DNW-A22 also incorporates the Sony Interactive
Status Reporting (ISR) feature to provide precise reporting
on errors/warnings on the equipment, thereby enabling
engineers to take appropriate action to correct the situation.
In addition, the drum assembly has been designed to
achieve easy, low-cost maintenance and to simplify both
mechanical and electric alignment after drum replacement.
Analog Composite Output
The DNW-A22 is equipped with two analog composite
outputs including one monitor output with character
superimposition.
Audio Monitor Output
RF Adaptor Output
The DNW-A22 is equipped with video/audio/DC outputs for
the optional RFU-89KB RF Adaptor. By using this RF
adaptor, playback pictures can be easily monitored on an
ordinary TV receiver.
RS-232C Remote Control
Various parameters can be set up and monitored via this
port by using the Sony ISR system.
