Features
The DSR-45A/45AP is a digital videocassette recorder
1
using / -inch tape. Offering the DVCAM™ digital
4
recording format, the DSR-45A/45AP 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-
45A/45AP allows you to configure various connection.
The built-in color LCD monitor lets you check images
easily.
The main features of the DSR-45A/45AP are described
below.
DVCAM Format
DVCAM is based on the consumer DV format,
which uses the 4:1:1 component digital format
(DSR-45A) or the 4:2:0 format (DSR-45AP),
and provides a 1 / -inch digital recording format
4
for professional use.
For details, see "Compatibility of DVCAM and DV Format"
on page 101 (GB).
Overview
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.
