AV Bridge USB and IP Streaming Device Page 1
Overview
Vaddio’s AV Bridge is a room based HD Media
Streaming appliance for USB and IP streaming of
content originating from traditional audio and video
equipment. The AV Bridge is designed for pro AV
applications offering a flexible audio and video
interface that’s controllable from an embedded web
server or front panel menu. A/V Bridge accepts a
multitude of video input resolutions from standard definition (480i/NTSC and 576i/PAL) up to HD 1080p/60 in
HDMI and YPbPr, including wide-screen VESA type PC resolutions (RGBHV) and it also incorporates stereo
audio inputs facilitating connection to professional AV equipment.
The USB streaming functions using MJPEG (Motion JPEG) and standard UVC (USB Video Class) with UAC
(USB Audio Class) drivers eliminating the need for installation of custom software drivers on the Host PC. The IP
streaming uses RTSP and HLS (Apple’s variant on HTTP streaming) and encodes H.264 video with AAC Audio.
The Ethernet port also provides access to internal web pages for control, set-up and updating the AV Bridge.
Use the AV Bridge in lecture/capture recording applications to “bridge” video and audio signals into a PC for
recording, storage, editing, rebroadcasting meetings or worship services and retrofit existing meeting rooms by
simply plugging a USB cable into a Host PC or connecting to an IP network.
The AV Bridge supports high definition encoding of audio and video sources, producing superior quality results at
the fraction of the cost of other products. The AV Bridge seamlessly integrates with Vaddio’s HD cameras,
presentation systems, video mixing consoles and audio products. The AV Bridge is an unsurpassable value
because of its ease of use and plug and play functionality.
Intended Use
Before operating the device, please read the entire manual thoroughly. The system was designed, built and
tested for use indoors, with the provided power supply and cabling. The use of a power supply other than the one
provided or outdoor operation has not been tested and could damage the device and/or create a potentially
unsafe operating condition.
Important Safeguards
Read and understand all instructions before using. Do not operate any device if it has been dropped or damaged.
In this case, a Vaddio technician must examine the product before operating. To reduce the risk of electric shock,
do not immerse in water or other liquids and avoid extremely humid conditions.
Do not connect Power over Ethernet (PoE) cables directly to the RJ-45 ports on the device as damage
may result.
Product Updates
From time to time Vaddio issues firmware updates for our products, which may render some information in this
manual inaccurate. Please check the current product release notes on https://www.legrandav.com/ for the latest
information.
Use only the power supply provided with the system. Use of any unauthorized
power supply will void any and all warranties.
Do not use “pass-thru” type RJ-45 connectors. If they are crimped incorrectly, they can damage the
connectors on the product, cause intermittent connections, and degrade signal quality. Physical
damage to the connectors will void your warranty. For best results use standard RJ-45 connectors
and test all cables for proper pin-outs prior to use.

First-Time Set-up with the AV Bridge:
The AV Bridge is a USB or IP streaming appliance that
provides a Plug & Play type interface (or bridge) between
traditional A/V room equipment and a computer using
Unified Communications (UC), lecture/capture, or
recording software.
The audio and video can work together as inputs to the AV Bridge, or can be used separately depending on the
requirements of the installation.
Diagram: The simple way to look at AV Bridge
The AV Bridge “bridges” the A/V signals into the PC for applications like lecture capture, recording, storage for
later playback, editing, distribution and other programs that can manipulate the content that the AV Bridge
provides.
Diagram: A small Lecture Capture System
This system uses a RoboSHOT HDMI camera, microphones, and the AV Bridge to encode the A/V signals to
USB 2.0 for use with the User’s PC and Lecture Capture software.

Installation Instructions
Step 1: Plug in the 18VDC, 2.75 Amp power supply included with the AV Bridge package. The front panel LCD
display will illuminate blue when the power is applied. The menu is now active and ready for configuration.
Step 2: Connect the Video Content Source(s) to the AV Bridge for USB 2.0 Streaming. More than one source can
be attached and selected from the front panel or web page menu. In this case a ProductionVIEW HD with HD-22
Cameras is connected to the HD-YPbPr input.
Step 3: Connect the Audio Content Source(s) to the AV Bridge. In this case, a mixer and really good mics are
connected using the balanced audio inputs.
Step 4: Connect the Host PC to the AV Bridge with the provided USB 2.0 Type-A Male to Type-B Male cable.
-OR-
Step 5: For IP streaming and control, connect the AV Bridge to the LAN which will allow set-up, configuration and
control of the AV Bridge via the internal web pages in AV Bridge from any of the approved browsers.
Step 6: From the front panel Menu System (Large Knob, Select and Cancel button), in this example, select the
balanced audio input, and select HD-YPbPr video input that are to be streamed.
Note: The AV Bridge will use DHCP (by default) to obtain an IP address when connected to the LAN.
The IP address will be viewable on the front panel menu. In absence of a DHCP server, the AV Bridge
will default to a Static IP address which is 169.254.1.1

Compatibility
We have tested this product with these web browsers:
•Chrome®
•Firefox®
•Microsoft®Edge and Internet Explorer®
•Safari®
We test using the browser version available from the vendor at that time. Other
browsers (including older versions of the ones on this list) are likely to work also.
AV Bridge is compatible with most soft conferencing applications, lecture capture applications, and media players.
The table below lists resolutions and frame rates available internally; the host computer and the AV Bridge auto-
negotiate these within the application, which may optimize for high quality or low bandwidth. An option for setting
video color space as 4:2:0 or 4:2:2 is available in the web interface. The 4:2:0 color space reduces USB
bandwidth by up to 25% and may actually improve video quality with some UC soft clients.
