Chapter 1 Overview
Features
The DSR-20/20P is a 1 /
4
-inch digital video cassette
recorder that uses the DVCAM digital recording
format. This system achieves stable, superb picture
quality by digitally processing video signals that are
separated into color difference signals and luminance
signals (component video).
The unit is equipped with a full-fledged analog
interface to support hybrid systems that combine
conventional analog equipment with digital equipment.
The DSR-20/20P’s main features are described below.
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 DV format’s 10-µm track pitch. 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).
Playback compatibility with DV format
A DV cassette recorded on a DV-format VCR can be
played back on this unit. (Cassettes recorded in LP
mode cannot be played back.)
Choice of two cassette sizes
The unit can use both standard-size and mini-size
DVCAM cassettes.
• According to cassette size, it automatically changes
the position of the reel drive plate.
• The maximum recording/playback times are 184
minutes for standard size cassettes and 40 minutes for
mini-size cassettes.
Other Features
Compact size
The unit achieves compact size suitable for using on a
demonstration or a bridal. The unit is also equipped
with basic functions that are needed for videocassette
recorders and players used in professional digital video
editing systems.
DC IN connector
The unit is equipped with the DC IN connector to use
in the case that the AC power is not available.
Menu system for functionality and
operation settings
The unit provides a menu system to make its various
functions easier to use and set up its operation
conditions.
Superimposition function
Time code, operation mode indications, menus, error
messages, and other text data can be superimposed and
output in analog composite video signals.
