Features
The DSR-60/60P is a
1
/
4
-inch digital videocassette
player designed to play back videocassettes recorded
in the DVCAM™ format. This system achieves
stable, superb picture quality by digitally processing
video signals that are separated into color difference
signals and luminance signals (component method).
The DSR-60/60P unit is equipped with the variety of
functions that are needed for videocassette players
used in professional digital video editing systems. It
supports the ClipLink™ function developed by Sony
Corporation for highly efficient video editing. When
connected to a Sony EditStation™, the unit serves as
part of a powerful non-linear editing system

.
The unit is also equipped with a full-fledged analog
interface to support hybrid systems that combine
conventional analog equipment with digital equipment.
The DSR-60/60P’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, 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-bit quantization), which offers
sound quality equivalent to the DAT (Digital Audio
Tape) format, or 4-channel mode (32-kHz sampling
and 12-bit quantization). On the DSR-60/60P, tapes
recorded in either of these formats can be played back.
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 playback times are 184 minutes for
standard size cassettes and 40 minutes for mini-size
cassettes.

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.
