Overview

Features

The DSR-45/45P is a digital videocassette recorder
using 1 / -inch tape. Offering the DVCAM™ digital
4
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 1 / -inch digital recording format for
4
professional use.
For details, see "Compatibility of DVCAM and DV Format"
on page 101 (GB).
Other Features
Built-in color LCD monitor
The unit has a 2-type color LCD (liquid crystal
display) monitor that lets you verify images on the
spot. You can see the setup menus, audio levels, and
system statuses. Menus and data can be superimposed
over the picture being displayed.
Duplicate, including cassette memory data
Using an i.LINK cable, you can duplicate a tape that
includes time code and cassette memory data, etc. If
the original tape has blank portions, you can duplicate
the tape skipping those portions.
Audio dubbing function
The unit allows you to record just the sound onto the
recorded tape (audio dubbing). (The tape must be
recorded in DVCAM format and the audio mode must
be 32 kHz.)
Menu system for functionality and
operation settings
The unit provides a menu system to make its various
functions easier to use and set up.
Superimposition function
Time code, warnings, menus, and other text data can
be superimposed on the MONITOR VIDEO output
and the LCD monitor.

GENERAL

Chapter
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.

Easy maintenance functions
• Self-diagnostics/alarm functions: The system
automatically detects an invalid operation, an invalid
connection or a malfunction, and displays a
description, a cause and a recovery method on the
LCD monitor and outputs the data from the
MONITOR VIDEO connector.
• Digital hours meter: A digital hours meter counts
four types of time data—operating time, drum
rotation time, tape running time, and tape threading/
unthreading. The digital hours data are indicated on
the menu.

Features
DV format compatibility
The unit can perform recording and playback in the
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/DV cassettes.
• According to cassette size, the position of the reel
drive plates automatically changes.
• 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 the
CONTROL S system Remote Control Unit (DSRM-
20, not supplied), or an editing controller that has an
RS-422A, RS-232C, or LANC jack.
High-speed search function
If you use an editing controller or the Remote Control
Unit (DSRM-20, not supplied), the unit has a picture
search function that allows you to view color pictures
at playback speeds up to 14 times normal speed (DSR-
45) or up to 17 times normal speed (DSR-45P) in both
forward and reverse directions.
You can also search frame-by-frame in jog mode.
While searching for scenes, you can also hear playback
audio.
Internal time code generator/reader
The unit contains a time code generator/reader that can
generate and read longitudinal time code (LTC) in the
SMPTE format (DSR-45) or EBU format (DSR-45P).
This unit can output the time code read from tape as an
analog (LTC) signal, and receive externally generated
time code (LTC).
