The DSR-45/45P is a digital videocassette recorder
using

-inch tape. Offering the DVCAM™ digital

recording format, the DSR-45/45P produces stable,
superior picture quality by digitally processing and
separating image signals into color difference signals
and a luminance signal (component video). Equipped
with five kinds of remote control connector (RS-422A/
RS-232C/LANC/CONTROL S/i.LINK), the DSR-45/
45P allows you to configure various connection. The
built-in color LCD monitor lets you check images
easily.

The main features of the DSR-45/45P are described
below.

DVCAM Format

DVCAM is based on the consumer DV format,
which uses the 4:1:1 component digital format
(DSR-45) or the 4:2:0 format (DSR-45P), and
provides a

-inch digital recording format for

professional use.

For details, see “Compatibility of DVCAM and DV Format”
on page 101 (GB).

High picture quality, high stability

Video signals are separated into color difference
signals and a 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
digital 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 fully 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), which provides four
channel simultaneous recording/playback.
