on content presentation and video conference. Thanks to Huddle Hub, these activities can be performed everywhere in your organization without the need of dedicated huddle rooms, large displays, webcams or other devices. In fact, Huddle Hub gives you access to a new and unprecedented collaboration mode. By using Huddle Hub, you can make your presentations and share your documents from the screen of your PC (desktop or laptop) directly to the screen of other devices (desktop PCs and laptops, tablets or smartphones), with no need for a specifically equipped place. Additionally, the camera streams of your devices can be collectively combined into a Multicam single feed to be used during videoconferences. The result is that every place in your company / organization can be used as a Virtual Huddle Room. The Huddle Hub solution is made of two components: • The Huddle Hub unit, currently available in two versions: Huddle Hub One (HHO) and Huddle Hub One+ (HHO+); • The Huddle Hub App (HHApp), a companion software available for Windows, MacOS, iOS and Android devices. Given that HHO+ includes all the functionalities of HHO, when this guide refers to HHO it means HHO or HHO+. HHO+ specific features will be highlighted with the HHO+ only marker. The following guide will show you how to get the best from your Huddle Hub App. Please see the Huddle Hub One Configuration Guide to understand how your HHO / HHO+ can be configured to better suit your needs.

To effectively run the Huddle Hub App and take part into a Huddle Hub session, your computer must have some minimum requirements. 2.1 MacOS App OS MacOS® 10.11 or higher CPU Intel Core i5 or faster processor Wi-Fi For Presentation: 802.11n 2.4 GHz wireless network adapter For Presentation + Multicam feed: 802.11ac 5 GHz wireless network adapter 2.2 Windows App OS MS Windows® 7 or higher CPU Intel Core i5 or faster processor Wi-Fi For Presentation: 802.11n 2.4 GHz wireless network adapter For Presentation + Multicam feed: 802.11ac 5 GHz wireless network adapter 2.3 Windows Portable App OS MS Windows® 7 or higher CPU Intel Core i5 or faster processor Wi-Fi For Presentation: 802.11n 2.4 GHz wireless network adapter 2.4 iOS App OS iOS® 10 or higher 2.5 Android App OS Android® 5 or higher

3.1 Desktop Apps To participate in a Huddle Hub session, you must have the Huddle Hub App or the Portable Huddle Hub App installed on your computer. They are available for download at the following address: https://www.hrt.website/app/ Alternatively, you can reach the download page by scanning the following QR code: Once you have downloaded the installer file double click to start the installation process. The installer will copy the Huddle Hub App in your default applications folder. Warning MacOS only: In order to complete the installation, you must be logged in to your computer with administrator rights. You will be prompted to perform Keyboard Shortcuts Enabling in the "Privacy" section of the "Security and Privacy" System Preferences. 3.1.1 Installing the Portable App on a USB dongle Warning: Available for MS Windows users. This limitation will be removed in future versions. If you are not logged in to your PC with administration rights, you will not be able to run the Huddle Hub App installer. In this case, you can use the Portable Huddle Hub App (available in the download area of the HRT website), that can be executed directly from an external storage device such as a USB dongle. The Portable Huddle Hub App has all the features of the standard Huddle Hub App, but it doesn’t support Multicam feed feature, because it requires the installation of a virtual driver, which is necessary to direct the Multicam feed to the videoconference software as if it was a webcam. 1. Download the Portable Huddle Hub App on your computer. 2. Insert in a USB port of your computer a USB dongle with a minimum free capacity of 50MB. 3. Copy the Portable Huddle Hub App file to the USB dongle. The Portable Huddle Hub App is now ready: select it on the USB dongle and launch it with a double click.

To participate in a Huddle Hub session, you must have the Huddle Hub App installed on your device. Check the HRT website in order to be directed to App Store Huddle Hub page: https://www.hrt.website/app/ Alternatively, you can reach the App Store page by scanning the following QR code: 3.3 Android App To participate in a Huddle Hub session, you must have the Huddle Hub App installed on your device. Check the HRT website in order to be directed to Google Play Huddle Hub page: https://www.hrt.website/app/ Alternatively, you can reach the Google Play page by scanning the following QR code: 4 Huddle Hub sessions For our purposes, a session is the sitting together of a group of people connected to HHO with their devices in order to make a presentation or a videoconference. The session starts when the first participant connects to HHO, and ends when the last participants closes his connection.

During a Huddle Hub session, we identify the following roles: • Participant (Desktop and Mobile Apps): anyone who is connected to the session. • Presenter (Desktop Apps Only): the participant who is currently sending his/her screen to the other participants. Presenter activates the Multicam feed feature – in order to start a videoconference – he becomes the host. During the videoconference, his computer is the one connected to remote room through the cloud videoconference software of his choice. • Viewer (Desktop and Mobile Apps): any participant who is receiving the presenter’s screen. When Multicam feed is active, the viewer continues to receive the presenter’s screen, at the same time his webcam stream is sent to the Huddle Hub unit to be combined to the other streams. Users of the current release of the mobile version of Huddle Hub App cannot assume the role of presenter. They can, however, receive the presentation (role of viewer) and send their camera stream to the Multicam feed. 4.2 Number of simultaneous sessions and participants Each Huddle Hub unit allows one teamwork session to take place at any time. Up to six devices (laptops, tablets and smartphones) can participate in a Huddle Hub session. If you want to allow multiple simultaneous sessions within your company, you can install more Huddle Hub units within the same network (clustered configuration). 4.3 Passcode protection The privacy of your session is protected by a Passcode. This is a 4 digits random number, generated when the session starts. The Passcode appears only in the black connection bar of the HHApp of the user that starts the session, or of the users that later have successfully joined the same session. People not invited to the session that, on purpose or by accident, try to connect to the same HHO unit, cannot join the session because they do not have the Passcode. In fact, whenever you want to connect to an in-progress session, you will be required to type the Passcode, which you will receive by one of the participants already joined that session. To join the session, just type the Passcode and click the Connect button.

Passcode protection is active by default, but can be disabled (see the Configuration Guide). Warning: If Passcode protection is disabled, users connected to your LAN could join your session by selecting the same hub in their Huddle Hub App and view the presented screen. 4.4 Reaching a Huddle Hub unit To start a Huddle Hub teamwork session, the participants’ devices need to be configured so that they can reach the HHO unit. This connection can be achieved through the company local network or through the HHO+ embedded access point (HHO+ only). 4.4.1 LAN connection The task of installing and configuring HHO to make it visible to all users on the LAN 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 the LAN, and you will see a list of all the active HHOs currently connected to the network. Warning: Although HHO and devices are properly configured to access the same LAN, you may still not be able to locate the hub in automatic mode. If this happens, contact your network administrator or consult the Configuration Guide. 4.4.2 Embedded Access Point connection (HHO+ only) You can directly connect to your HHO+, provided that it has been switched on and that you are in the range of its embedded Wi-Fi access point. To do so, on your device select the Wi-Fi name (SSID) of the HHO+ you want to connect to (default is “HuddleHubOne”). Under this configuration, you can reach only the HHO+ unit you are directly connected to. 4.4.3 Mixed connection (HHO+ only) If HHO+ is accessible both via the local area network and directly via its access point, it will be possible to participate in the same session with devices connected, either, through one or the other of the networks.

Automatic Discovery If HHO and your device have been properly configured, at its start HHApp will show the list of the available Huddle Hub units. This list is compiled and submitted to you through a network discovery service. When the service is enabled (and allowed by local network configurations), HHApp can automatically search for HHO units on the network. Warning: If your HHO has been properly configured, but does not appear on the list, please use the Discovery by IP function described below. Discovery by IP Although HHO and your device have been properly configured to access the same network, it may happen that your device is not able to automatically locate the hub. In that case, the black connection bar of your HHApp will show “No hub found” as in the following figure: In this case you will need to click on the magnifying glass icon, type the IP of your HHO in the Discovery by IP window and click the Discover button. If the address is correct, the name of the hub will appear in the center of the window, and then you can click the Connect button to create the connection. Warning: When connected directly to a HHO+ through Wi-Fi access point, you still may be able to reach other HHOs. This is made possible by a specific HHO configuration, when the Wi-Fi network interface Share mode is set to ”Routing + NAT” and the "Lan access to session only participants" flag is unchecked. Connecting to HHO via another HHO+ access point is not recommended. How to know the IP of your HHO When HHO is connected to the company LAN, its IP is either dynamically assigned by the DHCP server of the network or statically assigned during configuration. Please contact your Network Administrator to get the IP address of the HHO unit you want to connect to. HHO+ only: if the unit is connected to a TV or a monitor, you can read its IP address on the welcome screen.

In case your HHO+ is connected to a display through its TV port, in the welcome screen shown on the display itself you will find instructions about downloading the Huddle Hub App and about configuring the session. After starting the presentation, the welcome screen will be replaced by the copy of the presenter’s screen. 5 Attending a session with a Desktop App Start your HHApp from the icon you can find in your default applications folder. The app will position itself in your Status Menu (upper right area of your desktop) on MacOS and in tray bar on MS Windows: MacOS MS Window After that, it will remain idle until you click on its nine dots icon to open its menu, and select one of the available actions to send commands to one of the available Huddle Hub units or to the Huddle Hub App. MacOS MS Windows Hint: to be promptly available when you need it, Huddle Hub App will be automatically launched at computer boot. You can change this behavior by unticking the specific checkbox in the Settings menu. The icon on the right of the hub name informs you of the status of the unit. A white icon means that the hub is available, with no session in progress (no participants have connected to it yet): A black icon means that a session has already been started on that hub (there is at least one connected device), and the session is still open (the number of participants has not reached the maximum yet):

removed from the list. Warning: If your HHO has been properly configured, but does not appear on the list, please use the Discovery by IP function described below. 5.1 Starting or joining a session The session starts as soon as the first participant connects to the selected hub. The HHO unit will change color in the list of the available hubs, becoming black to represent the fact that it is busy. Other participants may join the same session (up to six). If the session is Passcode protected ask the participant that started it to tell you the Passcode. Your Huddle Hub App icon, in the Status Menu, will change color to remind you that you are connected to a Huddle Hub session (4 of the 9 points will become pale blue): 5.2 Leaving a session You can leave a session at any time, simply by clicking the white cross next to the name of the hub in the black connection bar of the HHApp: If you are the only remaining participant of the session, Huddle Hub automatically closes the session and returns available for new sessions. When you leave a session, the HHApp will not close itself, rather remaining available for new teamwork sessions. 5.3 Quitting Huddle Hub App If you want to stop Huddle Hub App, click on the three-dots icon of the app and select the Quit menu item. 5.4 Presenting Once the session has been started, content presentation can begin. Presentation consists of capturing the screen of the one participant and sending it to all the other participants in the session. The participant who send his/her screen is called Presenter, and the other participants are called Viewers. When one participant takes the role of Presenter, all the other participants become Viewers, and their devices automatically open a window showing the Presenter’s screen (presenter window).

HHO+ only: Huddle Hub One+ with connected TV if your session is hosted by a Huddle Hub One+ unit, which is also connected to a display through its TV port, the Presenter window will not open automatically, but if you want to follow the presentation on your device also you have to open it using the Open presenter window menu item. 5.4.1 Presenter window The presenter window contains the screen sent by the Presenter. It can be resized or closed using the buttons on the top bar. If closed, you can reopen the it by using the Open presenter window menu item. The Presenter window can be magnified and sent full screen. For this reason, the main presentation controls are available by right-clicking the mouse at any point in the Presenter window itself. 5.4.2 Becoming Presenter By default, at session start the presenter role is not assigned (you can change this behavior, see Settings) The participant who first selects the Present menu item becomes the Presenter. MacOS MS Windows When a participant becomes Presenter, the four colored dots of the HHApp icon in the Status Menu turn from pale blue to red:

their acceptance – one of the participants can at any time assume the role of Presenter. When this happens, the previous Presenter returns to the role of Viewer, and his computer opens the Presenter window that shows the new Presenter’s screen. 5.4.3 Pause, stop, lock The presentation can be paused or stopped using the corresponding items in the HHApp menu. The Pause command stops presentation and leaves the presenter window showing with the last frame sent, plus superimposed graphic and textual indications of the pause status. The Presenter can restart presentation at any time by using the Resume command The Stop command stops the presentation and cancels the participant's Presenter status, leaving the session with no Presenter. By using the Lock command during a presentation, you can prevent other participants from taking the role of Presenter, until you Unlock it again (or until you leave the session). 5.4.4 Overlay Pointer While you’re in the Presenter role, you can show your mouse cursor to the Viewers by selecting the Overlay submenu items Arrow pointer or Laser pointer. Presenter info From the Overlay menu, you can activate the Presenter info item to make HHO include your name in the display overlay on the screen. You can select the identifier you want to show by typing it in the My name field of the Settings window (the default is the name of your computer). Your name will be included in a black area located at the center bottom of the screen and in the caption of the Presenter window.

Sometimes teamwork sessions involve people located remotely, and each work group is used to the collaborative communication tool that prefers and that best suits its needs. During a presentation session conducted with Huddle Hub, the Presenter can participate in a videoconference (using the software that he prefers) and send to the Viewers the image of the remote participants that he receives on his screen. Additionally, the Presenter can activate the Multicam feed feature, that makes HHO capture videos from the all participants’ webcams, compose a single stream from them, and send it to the selected video conference software. Using this feature, videoconferencing will be more effective, natural, and comfortable, and will not force participants to shrink to one side of the table to get framed by a webcam or tamper with the remote control of a PTZ control camera. Below we will show how to activate and control the multicam feed. 5.5.1 Starting the Multicam feed Once the presentation has been started, the Presenter’s menu will populate with functions pertaining to the Multicam feed. It is therefore important to note that only the Presenter will have access to this feature. The command that starts the feature is Start multicam feed. The initial behavior of the app depends on the Huddle Hub model you are using and on its usage scenario: Huddle Hub One or Huddle Hub One+ without connected TV • All connected devices (including the Presenter) start capturing video streams from their respective cameras. • The captured streams are sent to HHO. • HHO mixes and composes them in a single stream, using the selected layout (see below) and the qualitative parameters set in the Settings window. • HHO sends the multicam feed to the Presenter's computer. • The preview of the Multicam feed is shown in the menu of the Presenter's HHApp. Huddle Hub One+ with connected TV • The Presenter’s video stream gets captured from his computer camera. • The captured stream is sent to HHO. • HHO sends the multicam feed to the Presenter's computer. • The preview of the Multicam feed is shown in the menu of the Presenter's HHApp. Huddle Hub One+ with connected TV and external Webcam • Only the External Webcam video stream is captured. • The captured stream is sent to HHO. • HHO sends the multicam feed to the Presenter's computer. • The preview of the Multicam feed is shown in the menu of the Presenter's HHApp.

command and determine the inclusion of his stream in the multicam feed. 5.5.2 Starting the videoconference Now the Presenter can start his favorite videoconference software, and select the video source corresponding to the Huddle Hub virtual driver. Warning: The Huddle Hub virtual driver is recognized by the videoconference software only when the multicam feed is active. Now you can start the videoconference session using the usual procedures that your chosen software requires. 5.5.3 Multicam feed quality settings The video resolution of the multicam feed produced by HHO and sent to the virtual driver can be changed in the Settings window. There are three possible options: • 640x360 (360p) • 960x540 (540p) • 1280x720 (720p) Warning: Your videoconference software might not compatible with a specific format: if this happens, try to change the Multicam feed quality settings to find a compatible one. 5.5.4 Device cameras To be included in a mixed stream, a device that participates a multicam feed session must send the image from its camera. In case your device has multiple cameras, you can select the one to capture with the My camera combo located in the Settings window. Stop my camera With the Stop my camera command, each participant can stop sending his device video stream, that will be excluded from the multicam feed. The video stream can be resumed using Start my camera.

In addition to the cameras of the connected devices, Huddle Hub One+ supports an additional USB camera directly connected to it. Thus, the resulting multicam feed can contain up to 7 streams, organized according to your layout preferences. 5.5.6 Multicam feed preview Starting the multicam feed causes the preview to open in the HHApp menu. The preview allows the Presenter to check if the participants are correctly framed and, consequently, to act on the layout before starting the videoconference. The multicam feed preview can be detached from the menu and displayed in an independent window: use the Undock multicam preview command available in the pop-up menu that appears when you hover with the mouse over the preview. Once separated, the preview window can be moved, but not resized. The preview window is a stay-on-top window that remains visible until you close it (it will go back in the HHApp menu). By right-clicking on the preview window, you open the pop-up menu that gives you access to the management of the multicam feed layout. 5.5.7 Multicam feed layout The multicam feed layout allows you to decide how the individual video streams get arranged in the multicam feed output stream. You can access the layout options by the pop-up menu that appears when you hover with the mouse over the preview (or right-click in the detached preview window). Undock multicam feed preview See above “Multicam feed preview” Speaker mode The mixed layout of the multicam feed contain a frame for every connected device. By default, these frames have the same size. The Speaker mode allows the participant that is currently speaking, the Speaker, to be more visible than the other participants, highlighted in a bigger frame. His video will occupy almost the entire surface of the multicam feed output, while the other frames will be organized in a row/column area called Video gallery. The Video gallery can be placed in any of the four outer edges of the multicam feed output surface (Top, Right, Left, Bottom), or totally excluded by the multicam feed (by removing the check from the Video gallery item). As for the Presenter role, the Speaker role is activated by the participants themselves, by using the command Set me as speaker. HHO+ only: if there is a USB webcam connected, its stream can be placed in the biggest frame as if it was a Speaker. The Host can achieve this result using the Set webcam as speaker command. The Host can also prevent other participants from taking the Speaker role away from the external webcam (thus

webcam command. Fill frame Abilitando l’opzione Fill frame, sia in modalità standard che in Speaker mode, gli stream provenienti dai dispositivi verranno adattati in modo da riempire completamente il multicam feed senza lasciare spazi neri sullo sfondo. Scegliendo questa opzione è importante accertarsi che i partecipanti vengano tutti correttamente inquadrati controllando la Multicam feed preview. 5.5.8 Co-presenter In order to allow Viewers to share their screen with the remote participants of a videoconference, the Presenter-Host can create a second presenter, called the Co-presenter. During a videoconference session, with the multicam feed active, the Presenter can use the Co-presenter command to invite a Viewer to share his screen: a list will appear, containing the names of the computers joined to the session (MacOS and Windows only). When the Presenter selects a Viewer from the list, the latter receives an invitation to share his screen, in form of a dialog box that requires confirmation. Upon his acceptance, Co-presenter window will open on the Presenter’s desktop. He can then share this window with the remote participants through the sharing tool of the video conferencing software itself. 5.6 Keyboard shortcuts Through the Keyboard Shortcuts window, available by the corresponding item in the three-dots menu, you can modify the keys assigned to some of the commands that control the session. 5.7 Settings Through the Settings window, available by the corresponding item in the three-dots menu, you can modify the configuration of the HHApp. The following list describes the parameters that you can configure: • My name (text): Identifies the Presenter in the Presenter info and in the Co-presenter selection menu. • My camera (selector): Allows choosing which camera of your device has to be sent to the multicam feed. • Automatic check for update (checkbox): if checked, at start-up HHApp will check for a more up-to- date version. If found, the Huddle Hub App download page will be opened in your default browser. • Launch at start up (checkbox): if checked, HHApp will be automatically launched at every boot of your computer. • Maximize presenter window on presentation start (checkbox): if checked, the Presenter window opens in full screen mode. • Disable power saving (checkbox): if checked, automatic power saving standby will be disabled during sessions, because it causes Wi-Fi disconnection (recommended).

presentation, to prevent them to be visible to the other participants. • When connecting to an empty hub... (selector): specify the action to perform at the starting of a new session. o Stand by: enters the session and waits for a command. o Present: starts presentation immediately while entering the session. o Present and start multicam feed: starts presentation and multicam feed immediately while entering the session. • Multicam output quality settings (selector): see Multicam feed quality settings above. 6 Attending a session with Mobile Apps When you attend a session with a mobile app, you’re allowed to take the role of the Viewer only. As a Viewer, you can receive the presenter’s screen. 6.1 Joining a session The session starts as soon as the first participant connects to the selected hub. When a session is started, the hub that runs it appears in the hub list. From that moment on, you can join the session by clicking on Connect button. 6.2 Leaving a session You can leave a session just by closing the App. 6.3 Presentation elements Presenter’s screen Presentation consists of capturing the Presenter’ screen and sending it to all the other participants in the session. When one participant (desktop apps only) takes the role of Presenter, you become a Viewer, and your device automatically opens a window showing the Presenter’s screen (Presenter window). Pointer Presenter can show his mouse cursor to the Viewers in the form of an Arrow pointer or Laser pointer. Presenter info Presenter can activate the Presenter info to make HHO include his name in the display overlay on the screen. Presenter’s name will be included in a black area located at the center bottom of the screen and in the caption of the Presenter window.

During a presentation session, the Presenter can participate in a videoconference (using the software that he prefers) and send to the Viewers the image of the remote participants that he receives on his screen. Additionally, the Presenter can activate the Multicam feed feature, that makes HHO capture videos from the all participants’ webcams, compose a single stream from them, and send it to the selected video conference software When the Presenter starts the Multicam feed, you can continue to receive the presenter’s screen, and, at the same time, you can send your camera stream to the Huddle Hub unit to be combined to the other streams. 6.4.1 Stop/Start my camera At any time, you can manually start/stop the capture of your camera by tapping on the camera preview, which determines the inclusion/exclusion of its stream in the multicam feed. When the Presenter starts the Multicam feed, the behavior of the app depends on the Huddle Hub model you are using and on its usage scenario: Huddle Hub One or Huddle Hub One+ without connected TV • Your app starts capturing video streams from your cameras: in this case, by tapping on your preview you can stop sending your video stream, and excluding it from the multicam feed. Huddle Hub One+ with connected TV (with or without external Webcam) • Your stream is not automatically captured and sent to the hub: if you want it and included in the multicam feed, you have to tap on the camera icon to start sending your video stream.
