The DSR-DU1 is a compact videodisk unit that is set to bring a new level of operational versatility to DVCAM
production. Introduced for use with Sony DVCAM and Sony DV camcorders*
1
, it provides up to three hours
of DVCAM/DV stream recording – equivalent to the maximum recording time of a DVCAM tape. Through an
i.LINK

(DV) connection, the output of the camcorder's camera is simultaneously recorded to both the hard
drive of the DSR-DU1 and the camcorder's tape cassette.
The DSR-DU1 is an extremely versatile unit. When a shoot has been completed, it can be detached from
the camcorder and used for field off-line logging or EDL creation, as a player for making dubs, or as a source
feeder machine for i.LINK interface equipped nonlinear editors. The DSR-DU1 also offers many other
convenient features that include loop recording to avoid missing an important scene, and interval recording
to capture scenes over a long period.
The i.LINK IEEE 1394 interface on the DSR-DU1 supports two types of protocols which are AV/C (Audio
Video/Control) and SBP2. The DSR-DU1 receives and stores the DVCAM/DV stream from compatible
DV/DVCAM camcorders using the AV/C protocol. The DSR-DU1 can then upload the DV files into
compatible i.LINK interface equipped nonlinear editors*
3
using either the SBP2 or AV/C protocol. In the case
of the SBP2 protocol, the DV files stored on the DSR-DU1 can be selected on a file basis from the GUI of
the compatible nonlinear editor, and then uploaded to the editor's hard drive at up to two times faster*
4
than
real time. The record start and stop time code values of each scene are also transferred to the editor,
eliminating the logging process common to nonlinear editing.
The DSR-DU1 presents an outstanding workflow innovation to DVCAM users in field acquisition and in
production.

DSR-DU1
*4 The time required to upload DV files from the DSR-DU1 may vary depending on the nonlinear editor used.In the case of downloading DV files from
a nonlinear editor to the DSR-DU1, only the DV AV/C protocol can be used and therefore only real-time speed is supported.
