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. 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
formats. This signal must comply with the SMPTE 12M standard.
Connect destination equipment to the LTC output BNC connector (lower
one).

5 Monitoring Output
Connect analog destination equipment to the connectors at the rear of
the DV-Bridge+. Use the BNC labeled Composite or the mini-Din
labeled S-Video for video output; use the two RCA labeled R and L for
audio output.
6 AC In
Connect the supplied AC power cord into AC inlet. Both 120 VAC and
220 VAC standards are supported by the DV-Bridge+ built-in power
supply.
2.2 Application Examples
The following figures show typical set-ups for using the DV-Bridge+.
Editing video and audio where the editing workstation operates in either
DV or 4:2:2 while the video source/destination is in the other is
illustrated in figures 2.2 and 2.3. Transferring video and audio from one
format to the other is illustrated in figures 2.4 and 2.5. Dubbing from a
DV source to a consumer VTR is shown in figure 2.6, while figure 2.7
shows how to monitor a DV-to-DV dubbing session.

The RS-422 DIP switch is set to Controlling. IEEE-1394 device control
from the workstation is transferred to the VTR via RS-422 Sony
protocol.

The RS-422 DIP switch is set to Tributary. RS-422 device control from
the workstation is transferred to the VTR via the IEEE-1394
NOTE : With Tributary option selected you must only connect one DV
device to the DV-Bridge+; the second IEEE-1394 port must remain
empty.
