1 DV-Bridge CAM – DV to SDI Decoder
1.1 Introduction
The DV-Bridge CAM is a lightweight and high-quality DV-to-SDI converter for low-cost newsgathering with
DV cameras. This compact interface can be mounted securely under a handheld DV camera, or sandwiched between a tripod and a camera, and enables operators to use DV cameras as if they were
SDI cameras.
The DV-Bridge CAM can be powered by the camera battery, and it outputs SDI with embedded audio and time code to enable the effective integration of DV cameras in an SDI facility. The interface is also ideal for creating very affordable auxiliary SDI cameras for mobile trucks. Alternatively it can be used with an editing workstation for DV to SDI playback.
1.2 Features
•
Decodes 25Mbps DV stream to digital video
•
Supports DV, DVCAM and DVCPRO formats
•
Support of 32, 44.1 and 48 kHz DV audio sample rates
•
SDI output features embedded Audio and Time Code (DVITC)
•
Switchable time code burn-in (OSD)
•
Digital Audio outputs locked at 48KHz. (Embedded)
•
4-pin and 6-pin IEEE-1394 ports
•
Convenient stand-alone package mounted between the camera and the tripod

GUIDE TO INSTALLATION AND OPERATION
2 Installation
2.1 Mounting the DV-Bridge CAM
The DV-Bridge CAM is configured to be mounted between the camera and the tripod in a production scenario. It may also be operated in a freestanding “tabletop” setup when used in a dubbing or postproduction situation.
2.2 Connections
Connectors for signal and power to the DV-Bridge CAM are located on the sides that are exposed when the device is mounted between the camera and its tripod. (see figure 2.1)
1
Figure 2.1
Edge views showing connectors and controls
The four connectors are as follows:
1. IEEE-1394a [4-pin]
2 3 4
2. IEEE-1394a [6-pin]
These two IEEE-1394a / iLink / Firewire connectors are multi-purpose. If DV Video is input to one, the other acts as an active loop-through. If the DV-Bridge CAM’s internal test generator is turned ON, both act as DV video outputs.
3. SDI video out [BNC]
4. Power IN [jack]
Power for the DV-Bridge CAM may be drawn from any convenient source. Its internal power supply can operate over a wide range of input voltages (from 6 to 17VDC).
•
A lockable jack connector is supplied with the DV-Bridge CAM so the user can construct an appropriate power cable.

GUIDE TO INSTALLATION AND OPERATION
3 Operation
3.1 User Interface
Operating controls for the DV-Bridge CAM are located on one of the sides exposed when the device is mounted between the camera and its tripod. (see figure 3.1).
Figure 3.1
Edge view showing controls
3.2 Operating Controls
The operating controls consist of a POWER ON/OFF pushbutton and associated status LED, and six DIP switches.
POWER BUTTON
The power button is located on the side panel adjacent to the DIP switches. The LED beside the button indicates the power status as follows:
•
OFF:
•
RED:
•
YELLOW:
•
GREEN:
The DV-Bridge CAM is turned OFF no DV video input signal, or errors detected in DV video input signal
DV video input is unstable; DV-Bridge CAM is unlocked
DV video input is stable; DV-Bridge CAM is locked.
•
Flash YELLOW: Internal test signal generator is ON
DIP SWITCHES
The 6 DIP switches are located on the side panel adjacent to the power button. The function of these switches is as follows:
1. Test [OFF / ON]
Turns ON and OFF the internal test signal generator.
The test signal generator sends a signal consisting of video color bars with embedded audio to the SDI output and also to both DV (IEEE-1394a) connectors. The audio on the left channel is pulsed on-and-off to assist in identifying channels for cable/connection purposes (on the SDI output only), and the color bars have a white central window superimposed that flashes in synchronism with the audio pulses. This test signal is designed to assist in system configuration and continuity checking. The DV-Bridge CAM’s Power Status LED will flash yellow when the Test switch is set to ON.
Note that the camera connected to the DV-Bridge CAM’s DV input should be set to “VTR” mode so that it will not be attempting to send a signal to its output, but instead will accept the signal originating in the DV-Bridge CAM.

2. Auto OFF [ENABLE / DISABLE]
Enables and disables the AUTO OFF mode.
Auto OFF is a power-saving mode. When enabled, the DV-Bridge CAM will shut down automatically if no signal is detected at its input for 30 seconds.
3. TC SOURCE [TITLE TC / REC. TC]
Selects the source of time code to be embedded in the SDI output and the OSD (see 6 below).
•
TITLE TC is the continuous time code that identifies position within a program,
•
REC TC is the source time code, usually time-of-day, that is recorded along with the program material.
4. FORMAT [DV / DVCPRO]
Selects the decoding to be performed on the input compressed video.
•
DV is appropriate for DV and DVCAM formats,
•
DVCPRO is appropriate for the DVCPRO format
5. STD [525 / 625]
Select the video format used in the production/editing environment.
6. OSD [OFF / ON]
Turn the On-Screen Display (OSD) of Time Code on and off.
When the OSD switch is set to ON, the Time Code (as selected by the TC SOURCE switch – see
3 above) is burned into the SDI output video. The TC is displayed in a semi-transparent window over the bottom center of the video frame.
