AV Bridge CONFERENCE 1
Overview
The Vaddio AV Bridge CONFERENCE is a room based HD Media Streaming solution enabling IP or USB
streaming. Like the original AV Bridge, it’s an appliance that “bridges” the room’s analog audio and video into a
computer (PC or Mac) for UC applications, but with one important distintction. The AV Bridge CONFERENCE has
been designed as an HD Encoder with 2-way analog audio to send the near-end audio to the far-end and return
the far-end audio to the application or pro mixer with AEC..
The AV Bridge CONFERENCE offers a flexible A/V interface that is controllable with an embedded web server
and the current settings are viewable from the front panel menus. It accepts a multitude of video input resolutions
from standard definition composite video (480i/NTSC and 576i/PAL) all the way up to HD 1080p/60 in HDMI and
YPbPr, including the most relevant wide-screen and 4:3 VESA type PC resolutions (RGBHV or DVI).
The USB streaming functions using MJPEG (Motion JPEG) and standard UVC (USB Video Class) with UAC
(USB Audio Class) drivers eliminate the need for installation of custom software drivers on the Host PC. The IP
streaming uses RTSP or 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, setup, and updating the software.
Use the AV Bridge CONFERENCE in UC conferencing applications to “bridge” video and audio signals into a PC
or retrofit existing conference rooms by simply plugging a USB cable into a Host PC or connecting to an IP
network.
The AV Bridge CONFERENCE supports high definition encoding of audio and video sources, producing superior
quality results at the fraction of the cost of other similar products. It seamlessly integrates with Vaddio’s HD
cameras, presentation systems, video mixing consoles, and other pro audio products with AEC. The AV Bridge
CONFERENCE is an unsurpassable value due to its ease of use, flexibility, and plug & play functionality, really.
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. 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

AV Bridge CONFERENCE 4
First Time Set-up with the AV Bridge CONFERENCE
The AV Bridge CONFERENCE high-definition
Audio/Video encoder is a USB/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.
An important feature of the AV Bridge CONFERENCE is the 2-way analog audio I/O that sends the near-end
room audio to the far-end and returns the far-end audio to the local room’s pro mixer with AEC. The AV Bridge
CONFERENCE is the ideal choice for existing rooms as well as new designs.
Diagram: The simple way to look at AV Bridge CONFERENCE
The AV Bridge CONFERENCE “bridges” the A/V signals into the PC for applications like UC conferencing, lecture
capture, recording, storage for later playback, editing, distribution and other programs that can manipulate the A/V
content. With the 2-way analog audio, the AV Bridge CONFERENCE is perfect for most UC conferencing
applications.

Diagram: UC Conferencing Application Example
This system diagram depicts the AV Bridge CONFERENCE in a UC Conferencing application using an existing or
new room audio system (providing for 2-way audio), video source, a PC, network and room monitor. The AV
Bridge CONFERENCE will output USB 2.0 streams or IP streams, but not simultaneously.
Installation Instructions
To install the AV Bridge CONFERENCE, follow the steps below to attach various pieces of equipment.
Step 1: Plug in the 18VDC, 2.75 Amp power supply included with the AV Bridge CONFERENCE system
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 CONFERENCE for USB 2.0 Streaming. More
than one source can be attached and selected from the front panel or web page menu.
Step 3: Connect the Audio Content Source(s) to the AV Bridge CONFERENCE. A DSP mixer with AEC and
good mics are generally a good idea. Use either the balanced or unbalanced audio input or output.Audio ins
and outs are needed for a UC Conferencing application to get the near end audio to the far end, and receive far
end audio for connection to the room’s audio system.
Step 4: For USB streaming, connect the Host PC with the conferencing application to the AV Bridge
CONFERENCE with the provided USB 2.0 Type-A Male to Type-B Male cable.
Step 5: For IP configuration and control, connect the AV Bridge CONFERENCE to the LAN, which will allow set-
up, configuration and control of the AV Bridge CONFERENCE via the internal web pages in from any of the
approved browsers. The system configuration is an important step in the installation.
This manual contains a Web Page Screen Shot Tour of the embedded web pages in the AV Bridge
CONFERENCE. This tour is provided to help the Administrator and User navigate the system.
Important Note: The AV Bridge CONFERENCE will use DHCP by default to obtain an
IP address when connected to the LAN. If no DHCP server is available, the AV Bridge
CONFERENCE will default to 169.254.1.1.The IP address will be viewable on the front
panel menu.

Initial Device Set-Up and Access
When any Vaddio product is shipped from the factory, there is no admin password and the administrative controls
are not available. For units using version 2.2.0 or later firmware, this is also true if you restore factory defaults,
which returns the device to a "like new" state. You must set the admin password using the web interface.
Functions Enabled after Initial Device Set-Up
Until the admin password is set and any other initial tasks are completed, the control and administrative interfaces
are not available.
•You will not be able to open a Telnet session to this product until you set the password using the web
interface.
•You will not be able to open a session over the RS-232 connection until you set the admin password using
the web interface.
•You will need to set the admin password again if you restore factory defaults.
Initial device set-up includes setting the admin password, and may include additional tasks. After initial device set-
up is complete, you will also need to complete system administration tasks in the web interface to define how the
device behaves as an element of your network.
Initial Access to the Web Interface
Enter http:// followed by the device's IP address or hostname in your browser's address bar.
The first time the product’s web interface is accessed, it presents a dialog box to set the password. This page
warns that the connection is not secure because the device does not support HTTPS.
You will also encounter this page after restoring factory defaults. After you complete the initial set-up, you will be
able to work with the product.
Create and confirm the admin password, and complete any other required tasks such as accepting agreements.
Then select Submit. The main administrative web interface opens.

Screen Shot: Streaming
The Streaming Page allows an administrator to set up the type of streaming, audio delay, USB streaming settings
and USB terminal type, color space, IP streaming settings, video speed and quality, protocol and path.
1. STREAMING MODE: USB 2.0 streaming or IP streaming (H.264); but not both at the same time. The Audio
may need to be delayed so it arrives concurrently with the video. Audio delay is like the lip sync control on a
BD player.
2. STREAMING SETTINGS: Add a device name (friendly name) and enable HID audio controls for applications
that allow it. USB Terminal Type depends upon the application and the room audio system configuration: Use
Type 0x405 when connecting to professional audio conferencing mixers with echo cancellation. Use Type
0x403 when connecting to audio equipment that does not have internal echo cancellation.
3. COLOR SPACE: Allows you to reduce the color depth to 4:2:0, which is used with applications where image
quality is not as critical or the window sizes available are small. The 4:2:2 color is used by many applications
that take advantage of the video performance where the colors are more vivid and precise.
4. IP STREAMING SETTINGS: Adjust IP Streaming performance. AV Bridge is set up for a variable bit rate; you
can select the resolution and the quality, such as High Quality (Best), Standard Quality (Better) and Low
Bandwidth (Good). We’ve tried to eliminate bad combinations of streaming parameters, so you can’t pick
1080p at a bit rate of 128Kbps, which would look totally gnarly…if it worked at all.
5. IP STREAMING PROTOCOL: Allows you to choose the streaming protocol – RTSP or HLS (Apple’s HTTP
Live Streaming).– and the RTSP port number. (HLS is always on port 80.) RTSP is best for live applications,
where HLS serves the Apple iOS devices and is better for playback due to the amount of buffering the HLS
has built-in. The Streaming URL auto-populates; the path can be changed.
6. When finished setting up the streaming parameters, click on Save to put the changes into effect or Cancel
to…cancel it.
