1 DV-Bridge+ DV To/From Digital Audio-Video Codec
1.1 Introduction
DV-Bridge+ is a compact, desktop unit designed to convert 4:2:2 (ITU-
601) video and AES-3id audio to and from DV compressed audio/
video. The DV-Bridge+ is ideal for interfacing consumer or professional
miniDV camcorders, VTRs, and editing or graphics systems equipped
with the IEEE-1394 (FireWire, i.LINK) interface to professional
uncompressed (4:2:2 and AES-3id) video and audio equipment. DV-
Bridge+ acts as either a DV encoder or decoder. When operating in
encode mode, DV-Bridge+ encodes material originating in 4:2:2 and
AES-3id to the DV format and outputs DV on the IEEE-1394 interface.
As a decoder, DV-Bridge+ decodes material arriving on the same IEEE-
1394 interface and converts it to 4:2:2 and AES-3id. Convenient
NTSC/PAL, S-Video and line-level analog audio outputs allow simple
monitoring or dubbing of the DV signal. DV-Bridge+ is ideal for a
number of recording, dubbing and monitoring applications in a mixed
DV/4:2:2 and AES-3id environment.
DV-Bridge+ also provides time code support (LTC, DVITC) and remote-
control capabilities through the IEEE-1394 ports and through a RS-422
serial port. The DV-Bridge+ features a simple user interface, using a
single button to control its functions and bi-color monitoring LEDs.
Some parameters are set using DIP switches on the bottom of the unit.
Input and output connectors are in the back, as is the power switch.

GUIDE TO INSTALLATION AND OPERATION

The DV-Bridge+ features a universal power supply, eliminating the
need for a separate power converter. A built-in anti-slip camera rest
allows a DV camera to sit conveniently in view to monitor its operation.

2 Installation
2.1 Connections
Refer to figure 2.1 and to the following description when connecting the
DV-Bridge+.
Figure 2.1 Rear view of the DV-Bridge+
1 DV In/Out
Connect a DV source to one of the DV connectors at the rear of the DV-
Bridge+ for input and output. Source must comply with IEEE-1394
(i.Link) standard. The 4-pin and 6-pin connectors effectively provide
active loop-through when the unit is turned on.
2 SDI In/Out
Connect an SDI signal to the SDI input BNC connector (left-hand side)
labeled SDI. The DV-Bridge+ accepts 4:2:2 serial digital video signals
in either 525 or 625 line formats. The input signal must conform to the
SMPTE 259M standard. For DVITC timecode support, insert a
timecode conforming to SMPTE 12M in the input signal. Connect
destination equipment to the SDI output BNC connector (right-hand
side). The DVITC timecode in the output signal respects the same
standard as the one in the input signal.
3 AES In/Out
Connect an unbalanced AES signal to the AES input BNC connector
labeled AES. The DV-Bridge+ supports 32, 44.1 and 48 kHz sample
rates. This signal must comply with the AES-3id-1995 (SMPTE 276M)
standard. Connect destination equipment to the AES output BNC
connector (right-hand side).
4 LTC In/Out
Connect an LTC signal to the LTC input BNC connector labeled LTC
(upper one). The DV-Bridge+ accepts LTC signals for 525 or 625 line
