Chapter 1 Overview
Advanced Recording and Playback
Functions
High-quality digital recording
The DVW-A500/1 series and DVW-500/1 series adopt
component digital video and a four-channel, 20-bit
digital audio recording system using an AES/EBU
format with a wide dynamic range. A digital signal
processing system that includes an advanced error
correction and concealment system that are unique to
digital Betacam provides superb video and audio
quality, while the adjusting and setting of a built-in
digital video processor ensures the output of precise
and stable video signals.
Playback compatibility with analog Betacam
and Betacam SP (DVW-A500/1 series only)
The DVW-A500/1 series provide playback capability
with tapes recorded on the Betacam SP VTRs, so that
Betacam users can upgrade to a digital environment
while enjoying continued access to the enormous
analog Betacam archives.
Noiseless playback with DT heads
Using the playback DT heads, you can perform
noiseless playback at 54 speeds ranging from –1 to +3
times normal speed, including still-picture playback.
Noiseless playback is also supported in the case of
both digital and analog Betacam playback.
Video and audio confidence heads
Video and audio confidence heads enable you to play
back video and audio signals on channels 1 to 4 while
recording, to check the quality of the recording.
Internal time code generator and reader
The internal time code generator allows you to record
LTC/VITC time codes and user bits together with
video and audio signals. Time codes and user bits are
read by the internal time code reader during playback.
Computer servo system
Computer-controlled servo motors provide direct drive
for the drum, capstan, and two reels, enabling quick
and accurate tape access.
Capstan override function
You can adjust the playback speed by ±15% to ensure
synchronization between, for example, two VTRs
playing back the same program.
Independent level controls
The recording and playback levels of each of the four
audio channels can be set indepenently during
monitoring of audio level meters.
Features for Ease of Operation
Compact, lightweight, low power consumption
The VTR is small and light enough to be used in
outside broadcast vans or in EFP (Electronic Field
Production) assignments.
Remote control operation
The VTR has a serial RS-422A 9-pin connector to
allow control of the VTR by an external control unit
through RS-422A communications.
The VTR also comes with 9-pin REMOTE1-IN(9P)
and OUT(9P) connectors to support bridge connection
of multiple DVW-A500/1 or DVW-500/1 series units
or other VTRs equipped with 9-pin remote connectors
for simultaneous operations.
Furthermore, by using the optional BKDW-509
Parallel (50-pin) Interface Kit, you can control the
VTR from an external control unit with a parallel
interface.
Digital hours meter
Three different hour displays and one cycle count
display are supported, showing total elapsed time since
the VTR was turned on, total drum revolution time,
total tape running time and total number of threadings
and unthreadings.
Self-diagnosis
When enabled through the maintenance menu, any
malfunction causes the VTR to perform self-diagnosis,
after which it displays the relevant error code in the
display.
Easy-to-maintain plug-in boards
The VTR uses plug-in circuit boards to simplify
servicing and inspection.
Mountable in standard 19-inch rack
The unit can be mounted in an EIA-standard 19-inch
rack.
For rack mounting, refer to the Installation Manual.
