Main Features

The DVCAM Format

The DSR-2000A employs the DVCAM format that is the
professional extension of the world-wide standard DV format.
Digital Component Recording
for Professional Performance
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 4:1:1 for excellent picture quality and superb
multi-generation performance. The DVCAM format has a wider
track pitch of 15 µm (compared with 10 µm for the DV format) that
gives higher reliability for professional editing.
The DVCAM format utilizes an intra-frame compression scheme and
is based on DCT (Discrete Cosine Transform) techniques with each
frame consisting of 10 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.
Track Pattern of the DVCAM Format
High-Quality Digital Audio
The DVCAM format also offers superior digital audio performance
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
and a four-channel mode with 32 kHz/12-bit recording.
Recording Capability of Up to Three Hours
DVCAM videocassette 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.
The long recording times of these very compact cassettes that have a tape
width of 1/4-inch
(6.35 mm) is made
possible through
Sony' s advanced
Metal Evaporated
tape technology.
Mini Standard
Playback Compatibility
with All DV (25 Mb/s)
Formats
The DSR-2000A boasts playback compatibility with all DV
(25 Mb/s) format recorded tapes. This is especially useful
because home-use DV products are now widely used in
professional video applications due to their compact portability
and superior picture quality. For maximum versatility in a
wide range of video editing environments, the DSR-2000A is
designed to play back DVCAM tapes, DV tapes recorded in
both SP/LP modes, and even DVCPRO tapes* without any
adaptor. Moreover, it is possible to use these tapes directly as
editing source material without the need for dubbing up to
other formats.
This unique compatibility saves time and improves productivity
as it eliminates the need to use different VTRs for each format.
*Not compatible with the SDTI (QSDI™) and i.LINK™ (DV In/Out) interfaces.
