1 Introduction
1.1 Huddle Hub
Huddle Hub™ product family is the answer to the needs of modern teamwork, which is increasingly
based on content presentation and video-conference. Thanks to Huddle Hub, these activities can be
performed everywhere in your organization, in traditional meeting or huddle rooms, but also in offices,
open-space areas, or even lounges. Every place in your company / organization - whether AV equipped
or not - can be used as a huddle room:
· Taking advantage of existing large displays and webcams, but also using only individual devices. Or
combining the two.
· With no cables for the TV, and no cables for the webcam.
· Running up to 7 concurrent sessions on a single Huddle Hub unit (Smart Rooms feature available in
MRE models only).
· Experiencing a smooth integration between Huddle Hub and your favorite video-conference software.

2 Understanding Huddle Hub
2.1 Rooms, Sessions and Roles
Rooms and Sessions
For our purposes, a session is the sitting together of a group of people, with the intent of either making
or assisting to a presentation, or to perform a video-conference.
A session happens in a room, which usually corresponds to a physical place where the participants
meet. However, HHO extends the concept of room to the group of participants that j oin the same
session, wherever they are.
For our purpose, we distinguish two kind of rooms:
· The room where the HHO unit is plugged to peripherals (TV and webcam), which we simply call room ,
or alternatively main room / primary room when we have to distinguish it from the Smart Rooms .
· The Smart Rooms , (HHO MRE and HHO+ MRE only, up to 6 Smart Rooms per unit), each one able to
host one fully independent session, to host sessions everywhere in your organization you can reach
your HHO unit through the L AN.
Each room is identified by a name, that can be set to match a specific place (e.g. "Main meeting room",
" 1 st floor huddle room" etc.) or a group of users it ' s reserved for (e.g. "Marketing dept.", "IT Demo", etc.) or
any other criteria that meets your needs.
A session starts when the first participant connects to a room, and ends when the last participant closes
his connection.
The following example portraits the situation of a company that has two HHO MRE units, each one with
four enabled rooms:
· HHO Ground Floor
o L obby
o Huddle room 1
o Huddle room 2
o Admin & Finance
· HHO First Floor
o Board room
o CEO ' s smart room
o Sales department
o Production department

Page 6 Huddle Hub User Guide
Passcode
Sessions can be protected with a passcode , which ensures the privacy of your meeting. The passcode
is a 4 digits random number, generated when the session starts, that is visible on the TV screen or in the
toolbar of the participant that started the session or in the one of the participants that already j oined it.
Passcode protection can be disabled.
Roles
During a session, we identify the following roles :
· Participant : anyone who is connected to the session.
· Presenter : any participant who is currently sharing his/her screen with the other participants.
· Viewer : any participant who is receiving the presenters ' screen.
· Host : we call "host" the presenter that starts a video-conference using the Wireless Camera, thus
sharing the VC software screen with the other participants.
· Active Speaker : during a video-conference based on Multicam, and with Multicam layout set to Active
speaker , the participants whose camera stream is in the main frame of the layout (HHO MRE and
HHO+ MRE only).
2.2 TV, Wireless Camera and Multicam
TV Sets and P r o j ecto r s
In a typical scenario, your HHO unit will be installed in a meeting room, huddle room or another shared
space, and will be connected to a large TV set with an HDMI cable . Switch on your HHO and your TV
and you will see the Welcome Screen , which contains instructions about connecting to that room and
about accessing the session. This Welcome Screen can be customized.
TV Sets and Projectors in Smart Rooms (HHO MRE and HHO+ MRE only)
In the Smart Rooms the HHO unit is not physically present, and there ' s no way to plug it to a TV set.
How do the participants see the presentation ?
There are a few possible options:
· Individual devices: any participant can receive the presentation on his/her own device , either a PC,
a tablet or a smartphone.
· TV set: smart TVs can receive the presentation through a web browser . Android TVs can receive the
presentation like any other Android device can. They j ust need to have the Huddle Hub Android TV app
installed. Other TVs need and Android dongle or set-top box attached to one of their HDMI ports.
· Mixed mode: some participants look at the presentation on their individual device, and the others on
the TV. This is always possible in the hub room

Page 7 Huddle Hub User Guide
W i r eless C ame r a
HHO can also connect a USB Webcam . This is not possible in the Smart Rooms , because it has to be
plugged to the unit.The HHO unit will make this webcam available to the HHApp clients connected to the
room, through a virtual camera driver, with no need of any cable.
Mu lticam (HHO MRE and HHO+ MRE only)
When a room webcam is not available, or when you decide not to use it, you can enable the feature
called Multicam , which allows up to 4 participants of a video-conference to use the cameras of their
own devices: their streams get captured and combined into a single one, to send to the video-conference
software of your choice, thus realizing a true multi-camera video-conference system. Multicam is
available only in the primary room and is alternative to the Wireless Webcam.
2.3 Reaching a Room
Whether you want to present your screen to the other participants, or to receive their presentation on
your device, you have to connect to a room . To achieve this, you have to:
1 . Connect your device to the same network HHO is connected to.
2 . Select the room you want to use for your presentation.
N et w o rk connection
The network to use can be either the company L AN or HHO+ embedded access point ( HHO+ only ).
LAN connection
The task of installing and configuring HHO to make it visible to all users on the L AN is your Network
Administrator’s responsibility. Under this configuration, your device will be able to access HHO through
the standard network configurations you already use to access your company L AN, and when you start
your HHApp, you will see a list of all the available rooms associated with the connected HHO units.
Warning : Although HHO and devices are properly configured to access the same LAN, in complex
network configurations you may experience problem in reaching the active rooms. If this happens, contact
your network administrator or consult the Configuration Guide.
Embedded Access Point connection ( HHO+ SRE and HHO+ MRE only )
You can directly connect to your HHO+ unit, provided that you are in the range of its embedded Wi-Fi
access point and that it ' s been configured to allow such a connection. To do so, on your device select
the Wi-Fi name (SSID) of the HHO+ you want to connect to. By default, the SSID is "huddlehub" and the
password is "huddlehub", but they may have been changed (recommended ! ). Ask your Network
Administrator for the HHO+ Wi-Fi credentials .

Page 8 Huddle Hub User Guide
Using this approach, you can reach only the rooms that belong to the HHO+ unit you are directly
connected to.
Mixed connection ( HHO+ SRE and HHO+ MRE only )
Both the methods described above can be used at the same time, and any session may have
participants connected either ways.
D isco v e r in g t h e r oom to connect to
Automatic Discovery Service
If both HHO and your device have been properly configured, at its start HHApp will show the list of the
available rooms. This list is prepared and presented to you through a network discovery service . When
the service is enabled (and allowed by local network configurations), HHApp can automatically search
for HHO rooms on the network.
Manual Search
In some network configurations, the automatic discovery service may not be able to reach all the HHO
units and show all their available rooms. For these cases, HHApp offer a Find Rooms function, that you
can use to reach the rooms through the IP address of the HHO unit that hosts them (see next chapter
about finding the IP address of a HHO unit).
2.4 F inding the I P address of a HHO unit
There are cases when you need to know the IP address your HHO unit:
· to download HHApp from the unit ;
· to configure HHO unit with its Web Console ;
· to attend a session using your web browser ;
· to connect to a room that cannot be reached through the discovery service .
When HHO is connected to the company L AN, its IP address is either dynamically assigned by the DHCP
server of the network or statically assigned during its configuration.
· If the unit is connected to a TV or a monitor, and no presentation is in progress, you can read its IP
address on the welcome screen. HHO+ units may have two IP addresses: one for the wired connection
and one for their embedded Wi-Fi network adapter.
· If other participants already entered that room, you can ask them to read the IP address they are
connected to ( ⁝ > Settings > Room info ).
· If none of the previous methods is possible, you have to contact your Network Administrator to get the
IP address of the HHO unit you want to connect to.

2.5 P erformances
HHO is capable of amazing performances. However, what you are actually able to do with it depends on
the unit type, on its configuration, on the IT infrastructure it ' s inserted into, and on the performances of
the computer and devices used as clients.

3 Attending a session with a Web Browser
The Huddle Hub solution offers you the possibility to start or attend a presentation session using j ust
your Web Browser (Chrome, Firefox or Edge), without installing or launching any software.
3.1 Starting or J oining a Session
First of all you need to connect to the HHO unit through its IP address. It is usually displayed in the
welcome screen of the main display of the room, if present. See Finding the IP address of a HHO unit
for other options.
Type the IP address in the address bar of your browser, and press Enter. If you are connecting to this
HHO unit for the first time, your browser will show a security warning. This happens because the SS L
certificate provided by the HHO web server is self-signed, and this is a normal situation with secure
servers located on embedded systems. You have to confirm you want to proceed:
You are now required to type your name (it will be saved for future connections) and, if other participants
connected before you, the room passcode (it appears in the welcome screen if nobody is presenting, or
in the browser/client window of the presenter and of the connected participants). Finally, click the Join
button to enter the presentation session:

If some other participant is already presenting his/her screen, you can:
· become the presenter (replacing the current one)
· add your screen to the presentation
· receive the presentation on your device

Page 12Huddle Hub User Guide
When you start presenting your screen , your browser will show a screen similar to the following one,
where you can choose what to share:

Page 13Huddle Hub User Guide
When receiving a presentation , you can make the presentation full-screen by double-clicking it, and if
multiple screens are presented at the same time you can right click your screen to to choose which
presented screen you want to receive on your device.
3.3 L ea v ing a Session
To leave a session, you have to click on the three-dots menu on top right of your browser page, then
select the Disconnect item:

Page 14Huddle Hub User Guide
4 Attending a session with the Desktop App
(Windows and MacOS)
Though a browser is enough to share content or receive a presentation from your PC, Huddle Hub App
provides a finer control.
At present moment, Huddle Hub App is also the only way to access the Wireless Camera feature.

2. From your Huddle Hub One unit
Connect to the web page your HHO unit (see Attending a session with a Web Browser ), click on the
three-dots menu on the right and select the Apps item:
10

Page 1 5 Huddle Hub User Guide
You will reach a page where you can download the version of Huddle Hub App suitable your PC.
R u nnin g / I nstallin g
Once you have downloaded the app file, launch it with double click. Huddle Hub App will offer you the
possibility to installed it in your applications folder, or to run it directly without installing. It can also be
copied on a USB memory stick (with a minimum free capacity of 50 MB) and launched from it.
4.1.3 Updating the Desktop App
When opening, Huddle Hub App checks if a new version is available. In that case, it shows a link that you
can click to open the general settings (same as ⁝ > Settings > General ) and download the updated
version. When the download ends, a small window will prompt you asking if you want to updated the
installed app (if it was installed), install it (if not installed) or simply launch it.
4.2 Starting or J oining a Session
To start or j oin a session, you must have Huddle Hub App installed and running. Unless you changed
your default setup, Huddle Hub App is configured to be started at boot and should be ready for you to
use. If this is not the case, you can start it from the icon you can find on your desktop or from your
default applications folder, according to your installation preferences.
The actual appearance of Huddle Hub App icon depends on your OS and on your screen settings, but it
will be similar to the following:

Page 1 6 Huddle Hub User Guide
When running, you can find Huddle Hub App in the Tray Area (Windows systems) or in the Status Menu
(MacOS systems), identified by HRT ' s nine-dots icon. Here is how it appears on different backgrounds:
After clicking the Huddle Hub App icon, a Toolbar similar to the following appears:
It lists the available rooms, together with icons that inform you about the availability of a TV screen or of
a webcam. By clicking on the stars left of the room names, you can add or remove any room from your
favorite list (favorite rooms show on top of the list).
If you have a long list of rooms and you want to search one by its name, you can type next to the
magnifier to filter the rooms by name. In the same area, you can also enter the IP address of the HHO
unit you want to connect to: if the IP address is correct and the unit is reachable, you will get the list of
the corresponding rooms.
You can now start a new session by simply clicking on any available room in the list. Rooms whose
name appears in bold, have a session in progress, and if you click on them you join that session .
When j oining a passcode-protected session started by someone else, a small window will ask you to
enter the passcode.
After you started/ j oined a session, the nine-dots icon in the tray area will turn blue:

Page 1 7 Huddle Hub User Guide
4.3 Sending and Recei v ing a P resentation
When you start a session, the Toolbar changes like in the following image:
The passcode appears only if the room has been configured to be passcode-protected. In this case, you
have to tell the passcode to the other participants in order to allow them to j oin your same session.
If some other participant is already presenting his/her screen, you can:
· become the presenter (replacing the current one)
· add your screen to the presentation
· receive the presentation on your device
P r esentin g y o ur sc r een
While you ' re presenting your screen, the nine-dots icon in the tray area turns red:

Page 1 8 Huddle Hub User Guide
and the Toolbar changes again to offer you new options:
You can now:
· pause the presentation : participants will see the last snapshot of your screen before you paused it ;
· stop the presentation : you will not be sharing your screen anymore ;
· lock the presentation : no other participant will be able to present his/her screen, until you unlock the
presentation again.
During a presentation, you will likely wish to hide the Toolbar by clicking on the button in its upper left
corner. To get the Toolbar visible again, you have to click on the nine-dots icon in your tray area again.
When a presentation has been paused, you can resume it anytime with j ust another click:
Recei v in g t h e pr esentation on y o ur de v ice
When you click the button to receive the presentation on your device, the Presentation window opens.
Whether this window appears maximized or not depends on your settings ( ⁝ > Settings > Presentation ).
Inside the Presentation window you can:
· press Esc if you want to restore the maximized presentation window to its previous size ;
· close the window not to receive the presenter ' s screen anymore ;
· right-click to select which screen you want to receive , when a multi-presentation is in progress.
