Overview
1-1 Features
The PDW-R1 is a convenient, compact, and lightweight
optical disc recorder. It allows you to record to optical
discs, play back optical discs, and record audio and video
data files transferred over the S400 (i.LINK
1)
) connector
and (network) connector. It is ideal for field
applications and for desktop viewing by journalists,
producers, and other production staff.

The features of the PDW-R1 include the following.
MPEG IMX/DVCAM recording
The PDW-R1 offers the capability to record and play back
both MPEG IMX
1)
and DVCAM
1)
streams. Users have
the flexibility to select from these formats according to
their picture-quality needs, or to match their editing-
format requirements.

Proxy AV data
Proxy AV data is a low-resolution, MPEG-4 based version
of a full-resolution MPEG IMX/DVCAM stream (a video
bandwidth of 1.5 Mbps and an audio bandwidth of 64 kbps
per channel). Whenever a recording is made, the unit
automatically generates proxy AV data from the full-
resolution data and records it on the Professional Disc.
Proxy AV data is much smaller in size than the full-
resolution IMX or DVCAM data. It can be transferred
quickly over computer networks, easily edited in the field
with laptop computers, and readily used in a wide variety
of applications, such as content management on small-
scale servers.
Thumbnail search operation
Simply press the THUMBNAIL button and the PDW-R1
instantly displays thumbnails on the video panel or a
connected monitor. You can easily cue up the desired
scene by guiding the cursor to the corresponding
thumbnail and confirming your selection with the SET
button.
Scene selection
You can create and play back clip lists of selected clips
from the disc, arranged in any order.
One disc can store up to 99 clip lists.
Clip lists make it simple to perform offline editing in the
field for later use with full-scale nonlinear editing systems
(XPRI
1)
, etc.).

Quick picture search by jog and shuttle
dials
The PDW-R1 has jog and shuttle dials as a conventional
VTR to search picture in a clip. The jog dial is for frame-
by-frame search at –1 to +1 times normal speed and the
shuttle dial is for high-speed search at ±20 times normal
speed.
IT-friendly system
In the PDW-R1, clips are recorded as video and audio data
files
1)
. This file-based recording system also allows
material to be viewed directly on a computer linked to the
unit via an i.LINK (file access mode, called FAM below)
connection—in the same way that a computer reads data
files on an external drive. The interfaces include the
S400 (i.LINK) connector, supporting AV/C (Audio/
Video Control) and i.LINK (FAM) protocols, and
(network) connector. The (network) connector
supports MXF (Material eXchange Format) file transfer
capability to exchange contents with other equipment
supporting MXF.
