Chapter 1 Overview
Features
The DSR-40/40P is a 1 /
4
-inch digital videocassette
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).
When connected to Sony Edit Station™, the unit
serves as part of powerful non-linear editing system
1) .
The unit is equipped with a full-fledged analog
interface to support hybrid systems that combine
conventional analog equipment with digital equipment.
The DSR-40/40P’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 (DSR-40) or
the 4:2:0 format (DSR-40P), 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 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
dubbing can be performed with virtually no
deterioration of quality.
Wide track pitch
The recording track pitch is 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).
Playback compatibility with DV format
A DV cassette recorded on a DV-format VCR can be
played back on this unit. (Cassettes recorded in LP
mode cannot be played back.)
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.
Facilities for High-efficiency
Editing
The unit provides an abundance of functions that
enhance editing efficiency and precision.
Remote control
The unit can be operated by remote control from an
editing controller that supports the RS-422A interface
or from a SIRCS
2) -system remote control unit such as
the optional DSRM-10, or DSRM-20.
1) Non-linear editing
This is an editing method that uses video and audio
signals that have been digitally encoded and recorded on
a hard disk as digital data. When compared with
conventional (linear) editing methods, non-linear editing
offers vastly improved efficiency in editing operations,
such as by eliminating tape transport time.

A command protocol to remote control Sony
professional videocassette recorders/players.
