Overview
Features
The DSR-DR1000A/DR1000AP is a digital video disk
recorder using the DVCAM
recorder using the DVCAM
TM
digital recording format. It
is the first professional DVCAM studio recorder to feature
a hard disk as its recording media.
The DSR-DR1000A/DR1000AP supports the jog, shuttle,
and variable playback modes found on conventional
VTRs, together with jog sound. In addition, it supports
many convenient functions possible only on a hard disk
recorder, such as simultaneous recording and playback,
random access, and interval recording.
This unit is equipped with an i.LINK* interface supporting
the AV/C and SBP2 protocols, which allows it to transfer
data at high speeds. It is also equipped with an Ethernet
connector, allowing it to be connected to a LAN for
transferring recorded data as files.
This unit can be used as a recorder in combination with
video cameras and players, and incorporated in a
conventional editing system as a professional feeder.
Because it adds a variety of convenient hard disk functions
to the functionality of a conventional VTR, it can
significantly increase editing efficiency.

superb picture quality.
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).
