Digitization is
opening up new avenues to success in many business areas. Nowhere is this
more
true than in
professional video production, where evolving digital technology is bringing
proven
advances in image
quality and equipment versatility as well as reducing operating costs.
DVCAM was born in
1996 as an extension of the consumer DV format, with which it is compatible.
With its superb
picture quality, excellent editing capabilities and multigeneration
performance,
DVCAM is the
perfect choice of format in the highly competitive world of professional
video.
The DSR-1P is a
dockable recorder for a camcorder, offering outstanding performance in the
acquisition
process. When the DSR-1P is combined with a Sony DXC-D35P or DXC-D35WSP
Digital
Camera, it
becomes a Digital Camcorder, providing a completely digital signal path and
perfect
ClipLink™
operation. For complete versatility, the DSR-1P incorporates both a Pro
50-pin analogue
and a Pro 76-pin
digital interface, enabling connection to both analogue and digital cameras.
The
DSR-1P features a
dual-size cassette mechanism that accepts both mini and standard size
cassette
tapes without any
special adaptors - a first in the history of dockable recorders. With its
superb
performance and
operating flexibility, the DSR-1P meets all the requirements of video
professionals.
Features
DVCAM Recording
Format for the Next Generation
The DSR-1P offers
superb picture quality, multi-generation capability and production
flexibility from its use of the
DVCAM digital
recording format - specifically developed by Sony for professionals in the
digital era.
Digital Component
Recording for Excellent Picture Quality
The DVCAM format
uses 8-bit digital component recording with a 5:1 compression ratio that is
identical to
the DV format. It
also offers a sampling rate of 4:2:0 for excellent picture quality and
superb multi-generation
performance. The
DVCAM format utilises an intra-frame compression scheme and is based on DCT
(Discrete
Cosine Transform)
techniques with each frame consisting of 12 tracks. Each track has video,
audio, ITI (Insert and
Track
Information) and sub-code sectors. It is the combination of ITI – a
reference signal used for precise
tracking – and
time code on the sub-code sector that helps to assure highly accurate
editing performance.
High-Quality Digital
Audio
The DVCAM format
also offers superior digital audio performance that is comparable to CD
quality, thanks to a
wide dynamic
range and excellent signal-to-noise ratio.
There are two
selectable audio channel modes: a two-channel mode with 48 kHz/16-bit
recording or
a four-channel
mode with 32 kHz/12-bit recording.
Playback
Compatibility with the DV Format
The DVCAM format
is the professional extension of the world-wide standard DV format, with
which it maintains
playback
compatibility. Thus all DVCAM equipment is capable of playing back DV
recorded tapes* without any
mechanical
adaptors. A wider track pitch of 15 µm (compared with 10 µm for the DV
format) gives the DVCAM
format higher
reliability for professional editing.

Excellent
Performance from Professional DVCAM Tapes
To gain maximum
performance from high-density digital recording, advanced Metal Evaporated
tape technology
has been
developed for the DVCAM format. The use of Sony’s pure cobalt advanced
evaporated coating gives
both high output
and high C/N (Carrier-to-Noise) ratio, resulting in superb quality pictures
and a low error rate.
A DLC (Diamond
Like Carbon) protective layer provides the enhanced protection of the tape
surface that is essential to avoid the possibility of damage during long
editing sessions. Finally, DVCAM tapes provide a low frequency of dropout
and superior thermal stability.
A variety of
cassette types is available to suit different applications. These include
types with or without an IC
Cassette Memory,
and a Master Tape. The built-in 16-kbit Cassette Memory stores ClipLink Log
Data, Index Pictures, Photo mode and other shooting data that enhance
editing efficiency. The tapes without IC Cassette Memory fit a wide range of
applications with affordable price. The Master Tape, which uses Sony Hyper
Evaticle II Magnetic Particle technology to provide higher output and lower
noise, is equally suitable for high-speed data transfer applications as well
as for making master recordings.
Recording Capability
of Up to Three Hours
DVCAM cassette
tapes are available in two sizes: standard and mini. The standard-size
cassette provides a
recording time of
up to 184 minutes while the mini-size cassette provides up to 40 minutes.
These long recording
times are
achieved in very compact cassettes with a tape width of only 1/4 of an inch
(6.35 mm).
