Playback Compatibility with
DV (25 Mb/s) Family Formats
For maximum versatility, the DSR-1500P is
designed to playback DV (25 Mb/s) format
recorded tapes without a mechanical
adaptor – and without requiring menu
switching of playback modes before use.
This playback versatility includes consumer
DV recorded tapes (SP mode) and even
DVCPRO* recorded tapes.
Moreover, it is possible to use these tapes
directly as editing source material with
±0 frame accuracy.
* Playback signal of a DVCPRO recorded tape is
not available via the SDTI (QSDI™) or i.LINK™
(DV In/Out) interface.
Versatile Interface Options
A range of versatile optional interface boards
is available, allowing flexible analogue and
digital system configurations.
Users can choose from the range of
interfaces to configure the DSR-1500P
to their individual requirements.
Alternatively, all three types of interface
boards can be installed simultaneously.
Thanks to these options, the DSR-1500P
can function as a compact, high-performance
professional editing VTR.
Digital Interfaces (DSBK-1501 Digital
Input/Output Board)
The optional DSBK-1501 Digital Input/
Output Board provides the DSR-1500P
with SDI*, SDTI (QSDI™)* and AES/EBU
digital audio interfacing.
Using SDI provides a direct video/audio I/O
between the DSR-1500P and digital
equipment such as Digital Betacam ® and
Betacam SX ® VTRs, while the AES/EBU
capability provides an interface to digital
audio mixers and so on.
This interface flexibility ensures upward
compatibility throughout the broadcasting
system.
SDTI (QSDI) allows virtually degradation-
free transfer of both video and audio signals
between the DSR-1500P and other SDTI
(QSDI)-equipped video equipment and
nonlinear editing systems.
- The SDTI (Serial Data Transport Interface) is
defined as SMPTE 305M.
- The SDTI (QSDI) is the DV compressed signal
interface which is defined as SMPTE 322M.
* Either SDI or SDTI (QSDI) is selectable by menu.

The DVCAM Format
for Professional Performance
The DSR-1500P employs the DVCAM
format, the professional extension of
the worldwide standard DV format.
The DVCAM format uses 8-bit digital
component recording with a 5:1 compres-
sion ratio and a sampling rate of 4:2:0.
The unique compression algorithm provides
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) which gives higher reliability for
professional editing.
It also offers superior digital audio
performance, providing a wide dynamic
range and excellent signal-to-noise ratio,
comparable to CD quality.
Alternative audio channel modes can be
selected: a two-channel mode with
48 kHz/16-bit recording or a four-channel
mode with 32 kHz/12-bit recording.
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.
