1 ASI-Bridge CAM: HDV to ASI Converter
1.1 Introduction
The ASI-Bridge CAM is an HDV (MPEG2 on IEEE-1394) to ASI (MPEG2 on coaxial) converter.
The ASI-Bridge CAM provides a convenient way of overcoming the operational limitations caused by the four
meter maximum cable length of the IEEE-1394 interface. ASI signals can be carried for over 300 meters on
coaxial cable, and over several kilometers by fiber.
For example, the ASI-Bridge CAM in combination with Miranda’s HD-Bridge Dec+ is the ideal way to connect
an HDV camera to an HD mobile truck. In a ‘News Gathering’ situation, the HDV MPEG2 stream of an HDV
camera passing through an ASI-Bridge CAM is naturally pre-formatted for transmission purposes. This new
approach allows HD news production to be very economical.
In a broadcast environment, it is possible to record satellite HD feeds on D-VHS for later transfer to an
MPEG2 on-air server. ASI is the way to transport the MPEG2 signal without any quality loss, so if the D-VHS
recorder does not provide an ASI output, the ASI-Bridge CAM can do the job..
1.2 Features
•HDV/IEEE-1394 to MPEG2/ASI interface
•DVB-ASI compliant
◊Supports the HDV cameras from Sony, JVC and Canon
•Transforms the VBR stream from Sony HDV cameras into a CBR 27Mbps stream
•Supported Formats:
◊SD 525/625: HD1 @ 19.8Mbps
◊HD 720p: HD1 @ 19.8Mbps
◊HD 1080i: HD2 @ 25Mbps
◊ATSC: 19.4Mbps
◊DVHS, STB, PVR: Any MPEG2/4 CBR Transport Stream between 500Kbps and 85Mbps
•Compact and slick camera-attached design
•Flexible 6V to 17V input power range
•Very low 2 Watts power consumption

2 Installation
2.1 Physical Installation
The ASI-Bridge CAM is designed to fit directly to the base of the camera, between the camera and its tripod
or shoulder mount.
♦Remove the camera from it’s tripod or shoulder mount.
♦Install the ASI-Bridge CAM onto the base of the camera
♦Reinstall the tripod or shoulder mount onto the base of the ASI-Bridge CAM
2.2 Connections
Refer to figure 2.1 and to the descriptions below when connecting the ASI-Bridge CAM.

HDV IN (IEEE-1394 iLink or Firewire interface) – Connect an HDV source to one of the two HDV
connectors. There is one 1 on the left side panel (small connector) as well as the one 2 on the
right side panel (large connector). The source must comply with the IEEE-1394 standard.
NOTE: you can only use one of the HDV connectors at a time. Do not connect sources to
both connectors simultaneously
3 ASI OUT (BNC Connector)
4 Power IN – connect an appropriate DC power supply (see technical specifications)

3 Operation
Turn the ASI-Bridge CAM ON using the front-panel power button (see fig. 3.1)
3.1 User Interface
The ASI-Bridge CAM has a very simple user interface, consisting of an ON/OFF pushbutton, and two status
LEDs.

Figure 3.1 ASI-Bridge CAM – Power button and status LEDs
1 Status LED – shows the signal status as follows:
RED No Signal
GREEN MPEG2 Presence Locked
YELLOW MPEG2 Presence, Unlocked
Flashing RED Problem / Error
Flashing GREEN Indicates the default HDV standard (see 3.2 below for details)
2 Power Button – push AUTO OFF / push ON / push OFF
–press and hold for more than 4 seconds to change the default HDV video
standard (see 3.2 below for details)
3 AUTO OFF status – shows the status of the power supply’s AUTO OFF mode, as follows:
GREEN Power Auto Off enabled
The AUTO OFF mode will cause the ASI-Bridge CAM to switch OFF automatically when no HDV input is
detected for 30 seconds, preserving battery power in some operational environments.
•Use the ON mode instead of AUTO OFF if occasional no-signal time intervals are expected and you
want to force the unit to remain ON.
The Status LED will be lit when the ASI-Bridge CAM is in the ON or AUTO-OFF modes.
