Overview
Features
The DSR-1600A/1600AP is a
1
/
4
-inch digital video
cassette player using the DVCAM digital recording
format. It achieves stable, superb picture quality by
digitally processing video signals separated into color
difference signals and luminance signals (component
method).
The unit is equipped with a variety of functions needed for
videocassette players used in professional digital video
editing systems.
The unit is also equipped with an i.LINK interface, thus
enabling simple connection with a nonlinear editing*
system supporting DV format.
Futhermore, the unit is equipped with a full-fledged analog
interface to support hybrid systems that combine
conventional analog equipment with digital equipment.
* Non-linear editing: This is an editing method that uses video and audio
signals digitally encoded and recorded on a hard disk as digital data. When
compared with conventional (linear) editing methods, non-linear editing
offers vastly improved efficiency in editing operations, for example, by
eliminating tape transport time.
The main features of the unit are described in the
following.
DVCAM Format
DVCAM is based on the consumer DV format, which uses
the 4:1:1 component digital format, and provides a
1
/
4
-inch
digital recording format for professional use.
High picture quality, high stability
Video signals are separated into color difference signals
and luminance signals, which are encoded and compressed
to one-fifth size before being recorded to ensure stable and
superb picture quality.
Because the recording is digital, multi-generation dubbing
can be performed with virtually no deterioration of quality.
Wide track pitch
The recording track pitch is 15 µm, fully 50 percent wider
than the 10-µm track pitch of the DV format. Thanks to this
feature, the DVCAM format sufficiently meets the
reliability and precision requirements of professional
editing.
High-quality PCM digital audio
PCM recording makes for a wide dynamic range and a
high signal-to-noise ratio, thereby enhancing sound
quality.
There are two recording modes: 2-channel mode (48-kHz
sampling and 16-bit quantization), which offers sound
quality equivalent to the DAT (Digital Audio Tape)
format, or 4-channel mode (32-kHz sampling and 12-bit
quantization). Cassettes recorded in either mode can be
played back on this unit.
Playback compatibility with DV and
DVCPRO formats
A DV cassette recorded on a DV format VCR (excluding
the tapes recorded in LP mode) as well as a DVCPRO
(25M) format recorded cassette can be played back on this
unit.
Note
When playing back a tape recorded in DVCPRO (25M)
format, the i.LINK output (see “Digital interfaces” on
page 7) of this unit is subjected to muting. Furthermore, it
is not possible to play back the cue-audio track of the tape.
