Chapter 1 Overview
The DSR-50/50P is a digital videocassette recorder
using
1
/4-inch tape. Offering the DVCAM™ digital
recording format, the DSR-50/50P produces stable,
superior picture quality by digitally processing and
separating image signals into color difference signals
and luminance signal (component video). Featuring a
color LCD monitor, the compact and lightweight DSR-
50/50P is portable and gives you the freedom to check
images on the spot.
The main features of the DSR-50/50P are described
below.
DVCAM Format
DVCAM is based on the consumer DV format, which
uses the 4:1:1 component digital format (DSR-50) or
the 4:2:0 format (DSR-50P), 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 signal, 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 about 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 bits linear code), which offers
sound quality equivalent to the DAT (Digital Audio
Tape) format, or 4-channel mode (32 kHz sampling
and 12 bits nonlinear code), which provide four
channel simultaneous recording/playback.
DV format compatibility
A DV cassette recorded on a DV-format VCR can be
played back on this unit (SP mode only). You can also
record an image on a DV-format (SP mode only).
(Recording/playing an image in LP mode is not
available.)
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 (DVCAM format).
Remote control
The unit can be operated by remote control from a
CONTROL-S system remote control unit, the DSRM-
20 (not supplied).
