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
D emo", 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 5 Huddle Hub Installation 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
D uring 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 Webcam and Multicam
TV Sets and Projectors
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 H D MI ports.
· Mixed mode: some participants look at the presentation on their individual device, and the others on

Page 6 Huddle Hub Installation Guide
the TV. This is always possible in the hub room
Wireless Camera
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.
Multicam (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.

serious damage to it.
· Place HHO in a location where it can be connected to a power source, and to TV and webcam (if
required).
· Make sure the cables and power cord are safely placed out of the way, so they do not create a
tripping hazard.
· K eep the product away from devices with strong electromagnetic reference, such as cordless
phones and microwaves. To access your HHO through its Ethernet interface, the unit must be
connected to the company L AN using an Ethernet cable.
Power Cord and A C -D C A da p ter
The power cord is country specific, to be compatible with your country AC sockets.
The supplied AC- D C adapter input voltage range is 9 0 – 264 VAC and the output is 12 V – 5 A - 6 0W.
Warning : You are required to use the supplied AC-DC adapter only.
L- s h a p e and V E S A mountin g k it , screws k it
The L -shape mounting kit can be used to secure the unit on walls, tables, rack cabinets, etc.

To switch HHO on again, simply press the power button.
Warning : at the very first power-on, HHO starts the automatic firmware installation procedure. This
operation takes few minutes. After the first installation, and at every power-on or reboot, HHO
connects to the HRT software repository to check for firmware updates and automatically installs its
own latest release. For this reason, HHO may appear unresponsive for few minutes after power-on or
reboot. The effective time required for the update depends on the speed of the Internet connection.
Please see the Configuration Guide if you want to disable the auto-update feature.

4 Deployment
4.1 Usage Scenarios
As explained in the Introduction, the Huddle Hub product family gives you access to new and
unprecedented collaboration models.
You can make your presentations from the screen of your computer or mobile device to a TV, but
also to the screen of other devices, with no need for a specifically equipped place.
See chapter Rooms, Sessions and Roles to understand the difference between the room where
your HHO is actually located and plugged to a TV set and a webcam, and the Smart Rooms ,
additional rooms made available for presentations by HHO MRE and HHO+ MRE models. In the
following chapters we will show some typical usage scenarios.
The HHO MRE and HHO+ MRE units can be configured for different Operation modes . What should
drive you in selecting the best option for your needs is not the size of the room or the number of
seats, but rather the number of participants who will receive the presentation on their own PCs or
mobile devices.
Please see the Configuration Guide for more information about the Operation modes.

Page 13Huddle Hub Installation Guide
4.1.1 Huddle Room
Huddle Rooms are small meeting areas, typically seating
4 to 8 people.
In such a room, you can connect your large display - if
any - to the H D MI port of HHO. If your room does not
feature a large display nor a pro j ector, you can still use
HHO to make presentations, simply sending them
directly to the screen of the other participants ' PCs or
devices.
If a webcam is also available, you can plug it to the USB
port of HHO and enable the Wireless Webcam feature.
If no webcam is available, you can configure your HHO to
enable Multicam , a unique feature that allow capturing
the streams of the individual device cameras and
combining them into a single stream to be sent to your
favorite video-conference software.
The Operation mode of each HHO unit is configured by default to the option Huddle , which offers the
best performances in this situation (see the Configuration Guide for more information about the
Operation modes).
4.1.2 Meeting Room
Meetings Rooms are larger meeting areas, typically
seating 8 to 2 0 people.
In such a room, you can connect your large display - if
any - to the H D MI port of HHO. If your room does not
feature a large display nor a pro j ector, you can still use
HHO to make presentations, simply sending them
directly to the screen of the other participants ' PCs or
devices.
If a webcam is also available, you can plug it to the
USB port of HHO and enable the Wireless Webcam
feature.
If no webcam is available, you can configure your HHO
to enable Multicam , a unique feature that allow
capturing the streams of the individual device cameras
and combining them into a single stream to be sent to
your favorite video-conference software.
If your unit is a HHO MRE or HHO+ MRE model, its
Operation mode can be configured to the option Meeting , which allow sending the presentation up to
64 participants ' , at the price of disabling the Smart Rooms (see the Configuration Guide for more
information about the Operation modes).

Page 14Huddle Hub Installation Guide
4.1.3 A uditorium
The HHO MRE and HHO+ MRE
models support a third Operation
mode , called Auditorium , which allow
up to 15 0 participants receiving the
presentation on their devices and is
perfectly suitable for large
conference rooms.
L ike in the Meeting mode, Smart
Rooms get disabled, and in this
situation also the quality of the
presentation stream gets reduced
to H D instead of Full H D , and the
frame rate lowered from 30 to 5 fps.
Please see the Configuration
Guide for more information about
the Operation modes.
4.1.4 Smart Rooms ( HHO MR E and HHO + MR E only )
In our terminology, a Smart Room is any place in your organization where you connect to a HHO room
to make or receive a presentation: an office, an unequipped huddle room, even a lounge.

Page 1 5 Huddle Hub Installation Guide
When you want to make presentations using the TV screen of rooms other than the main room where
your HHO unit is placed, obviously you cannot plug them to the HHO unit, but you have to exploit HHO
ability to send presentation to the screen of other devices. In fact, those TV sets can receive the
presentation provided that they are:
· Smart TVs , with a compatible web browser can receive the presentation through the web viewer .
· Android TVs , which can receive the presentation through the Android TV client .
· Standard TVs , equipped with an Android dongle or set-top box.
In any other place in your company, which is not equipped with a large display, you can advantage of
HHO collaboration facilities for an impromptu or ad hoc meeting: the possibility to present and receive
directly on laptops and mobiles, without the need for a TV.
The only condition is that you are able to reach the HHO unit through the company L AN. Provided that
this connectivity condition is respected, the actual location of your HHO unit is not relevant, it can be
placed anywhere in the company: in a traditional huddle room, but also a data center, server room or
any other place under IT Manager’s control.
4.2 N et w or k Topology
In the following chapters we will discuss the possible network configuration options. In all cases we
will highlight the possibility to have participants with full access to the company L AN, and others
restricted to the role of guests, able to receive the presentation on their devices and also to present,
but with no access to other resources.
· HHO features a wired network adapter, and there is j ust one possible configuration: connecting it to
the company L AN.
· HHO+ has also a wireless network adapter, which can be configured in Station Mode (client of an
AP) or in Access Point Mode. The combination of these two wired/wireless interfaces leads to
some possible network topologies.
Please see the Configuration Guide for details about settings your HHO unit for a specific
configuration, and the Network Security Guide for recommendations on how to make a secure
deployment of a HHO unit in your network.

Page 1 6 Huddle Hub Installation Guide
4.2.1 Single N et w or k
Wired Connection
This is the only network configuration allowed by Huddle Hub One, which has a single, wired network
adapter.
In this configuration, HHO wired network interface is connected to the company L AN through an
Ethernet cable. The corporate users remain connected to their usual Wi-Fi network and their devices
reach HHO through a company access point.
Corporate network can be configured to show Huddle Hub also to guests and contractors - as usually
done for printers and scanners. The creation/configuration of a guest network with restricted access
is a Network Manager ' s responsibility.
To be used by the devices, HHO doesn’t need any Internet access. However, Internet access is
necessary to allow HHO to download its updates.

Page 1 7 Huddle Hub Installation Guide
Wireless Connection ( HHO + only )
In case you install your HHO+ unit in a place where you have no wired connection to the company
L AN, you can configure HHO+ wireless network adapter in Station Mode to make it as a client of a
corporate access point.
In this configuration, HHO+ is connected to the company L AN via its Wi-Fi module, through an access
point, as the other company devices do. The corporate users remain connected to their usual Wi-Fi
network and their devices reach HHO+ through a company access point.
Corporate network can be configured to show Huddle Hub also to guests and contractors - as usually
done for printers and scanners. The creation/configuration of a guest network with restricted access
is a Network Manager ' s responsibility.
To be used by the devices, HHO+ doesn’t need any Internet access. However, Internet access is
necessary to allow HHO+ to download its updates.

Page 1 8 Huddle Hub Installation Guide
4.2.2 Dual N et w or k
A ccess P oint Mode ( HHO + only )
In this dual network configuration you use the wired network adapter to connect to the company L AN,
and set HHO+ wireless adapter to Access Point Mode to provide an additional Hot Spot and grant
limited access to guests.
Corporate users reach HHO+ through the company L AN, while guests connect directly to the SSI D
provided by HHO+. The two network adapters can be configured to create mutually isolated networks,
or to some level of communication (for example to provide Internet access to guest, at the same
time preventing any access to the corporate L AN).
To provide Internet access to the connected guest devices, HHO+ must have Internet access itself.
Internet access is also necessary to allow HHO+ to download its updates.
