Overview
The DSR-11 is a '/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).
With a compact, lightweight and space-saving case,
the unit can be installed vertically and is equipped with
an analog interface as well as a digital interface
enabling connection to a digital device such as a
computer.
The DSR-11 '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 (NTSC) or the
4:2:0 format (PAL), and provides a '/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
digital dubbing can be performed with virtually no
deterioration of quality.
Wide track pitch
The recording track pitch is 15 urn, fully 50 percent
wider than the DV format's 10-um 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 linear code), which offers
sound quality equivalent to the DAT (Digital Audio
Tape) format, or 4-channel mode (32-kHz sampling
and 12-bit nonlinear code).
DV format compatibility
A DV cassette recorded on a DV-format VCR can be
played back on the unit (SP mode only). The unit can
also record in DV format (SP mode only). (Recording/
playing back an image in LP mode is not available.)
