Overview
1-1 Features
The PDW-D1 is a compact and lightweight
disc drive which, connected to a nonlinear
editor, allows recording/playback of video/
audio data. Connected to a computer, it can
also be used to write and read video/audio
data files and general-purpose data files.
In conjunction with a laptop computer it is
ideal for field use, or for building a budget
video production system together with a
nonlinear editor.
The features of the PDW-D1 include the
following.
DVCAM format recording/
playback
By accessing this unit from a computer with
the AV/C (Audio/Video Control) protocol,
you can record or play back a DVCAM
1)
format data stream.
1) DVCAM is a trademark of Sony Corporation.
DVCAM output from MPEG
IMX recorded disc
By playing back a disc recorded in MPEG
IMX
1)
format from a computer with the
AV/C protocol, a signal converted to the
DVCAM format can be output.
1) MPEG IMX is a trademark of Sony
Corporation.
Recording video and audio
data as files
You can record video and audio data in
MPEG IMX format or DVCAM format as
files, through the 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 at
upto 30 times faster than real time.
IT-friendly system through
i.LINK interface
In the Professional Disc, clips are recorded
as video and audio data files. This file-
based recording system also allows material
to be viewed directly on a computer linked
to the PDW-D1 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.
