Overview
1-1 Features
The PDW-V1 Professional Disc Recorder is a compact and 
lightweight unit, offered as an affordable solution for 
playing back optical discs as well as for audio and video 
data file recording through its 
 
(network) connector or 
S400 (i.LINK
 1)
) connector. It is ideal for field 
applications, and for desktop viewing by journalists, 
producers, and other production staff.
1) i.LINK is a trademark of Sony Corporation.
The features of the PDW-V1 include the following.
Playback of MPEG IMX/DVCAM
The PDW-V1 offers the capability to 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.
1) MPEG IMX and DVCAM are trademarks of Sony Corporation.
Recording video and audio data as files
Though the PDW-V1 does not have video and audio input 
connectors, it is possible to record AV data as files through 
its 
 
(network) connector or  S400 (i.LINK) connector. 
Proxy AV data
The proxy AV data is a low-resolution, MPEG-4 based 
version of the full-resolution MPEG IMX/DVCAM 
stream. When a full-resolution MPEG IMX/DVCAM file 
is transferred, a proxy AV stream file that is time code 
synchronized with the full-resolution stream, is also 
created automatically on the disc. This proxy AV data, 
which is smaller in size, is easier to work with and can be 
transferred over common networks at much greater 
speeds. The proxy AV data can be transferred at upto 30 
times faster than real time.
Thumbnail search operation
Simply press the THUMBNAIL button and the PDW-V1 
instantly displays these thumbnails on either its LCD 
display 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.).
1) XPRI is a trademark of Sony Corporation.
Quick picture search by jog and shuttle 
dials
The PDW-V1 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 times normal speed and the shuttle 
dial is for high-speed search at up to ±20 times normal 
speed.
IT-friendly system
In the Professional Disc, 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 PDW-V1 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.
