Overview
Features
The DSR-2000/2000P is a
1
/4-inch digital videocassette
recorder using the DVCAM
TM
digital recording format.
It uses a component video system, with separate
luminance and chrominance signals and digital
processing to realize a stable, high image quality.
This unit is equipped with a variety of functions
needed for videocassette recorders and players used in
video editing. By combining two units, you can easily
assemble a cut editing system. It is also equipped with
a full-fledged analog and digital interfaces to support
hybrid systems that combine conventional analog
equipment with digital equipment. Furthermore, it
supports the Sony-developed ClipLink
TM
function,
improving operating efficiency when combined with a
Sony EditStation
TM
.
The following are the principal features of the unit.
DVCAM Format
DVCAM is a professional
1
/4-inch digital recording
format developed by Sony from the consumer DV
component digital format (4:1:1 for DSR-2000/4:2:0
for DSR-2000P).
High image quality and high stability
The luminance and chrominance signals are encoded
separately, with a
1
/5 compression, giving a stable high
quality video image.
Since this is a digital system, nth-generation copies
created by repeated dubbing show virtually no loss in
picture quality.
Wide track
The recording track width is 15 µm, 50% wider than
the 10 µm of the DV format. This ensures adequate
reliability for professional use.
PCM digital audio for high sound quality
The PCM encoding method yields a high audio
quality, with wide dynamic range and high signal-to-
noise ratio.
There are two recording modes: two-channel mode
(48-kHz sampling and 16-bit quantization), which
offers sound quality equivalent to the DAT (Digital
Audio Tape) format, or four-channel (32-kHz
sampling and 12-bit quantization).
Playback compatibility with DV and
DVCPRO formats
A DV cassette recorded on a DV format VCR as well
as a DVCPRO(25) format recorded cassette can be
played back on this unit.
Note
When playing back a tape recorded in DVCPRO
(25M) format, the SDTI and i.LINK outputs (see the
section “Digital interfaces” on the next page) of this
unit are muted. Furthermore, it is not possible to
playback the cue-audio track of the tape.
