Managing Calls through the Web Interface

To access the call log and the parameters of an active video session, go to the Conference tab.

Depending on the parameters of the network that is used to connect the endpoint to your device, the video from your camera, as well as conference feed may be delayed.

If the PTZ camera image is freezing or if changing video layout takes longer than it should, it does not mean that the system is malfunctioning. Most likely, other meeting participants do not experience any issues.

Previews in the web interface are displayed at a rate of no more than 5 frames per second to reduce the load on network resources.

Changing devices

During a session, you can change the device used for streaming in the video layout with TrueConf Group on the fly. To do this, navigate to the tab, select the screen , and in the section. You can specify another webcam connected to the terminal or one of the capture card inputs. Additionally, you can change the device by switching angles.

To change the microphone or speakers used by the terminal, go to the section and select the desired devices in .

Camera Settings

There are two blocks for displaying feeds at the top of the page:

In each of them, you can select the type of content to be displayed:

• Primary source – view the image from the camera connected to TrueConf Group (self-view). You will have access to control it (for compatible PTZ cameras). You can select your camera as the prioritized window in the video layout by clicking .

• Presentation source – preview of the content prepared for sharing. You can make the presentation the priority window in the video layout by clicking .

• Main display: Display the layout on the screen connected to the endpoint and control the video feed from the endpoint camera

• Conference layout – select the current layout and manage mixing settings for a group conference (available only when the MCU function is activated; if MCU is not available, the conference layout will display video from the connected camera);

• Participant – displays video from the selected participant and allows PTZ camera control.

If necessary, you can disable the display of the video window in the web interface by clicking . However, this window will still be visible in the video layout.

Content Sharing

The terminal allows you to view presentation materials outside of a video session. During a video session, you have two options for behavior:

Behavior Option	Option Description
Transmit by Button	A new video window with a preview of the selected content will appear on the terminal screen for confirmation
Transmit on Connection	Content sharing in the conference starts immediately

TrueConf Group supports:

• transmission of content from devices connected via HDMI cable (available in certain configurations only);

• demonstration from an external USB drive and internal storage of images in PNG, JPG, TIFF formats, PDF documents, MKV, MP4, TS videos;

• displaying content from a second webcam connected to the terminal. For example, if a USB PTZ camera is used to transmit video from the meeting room, and you have also connected a laptop for content capture via an HDMI capture card;

• transmission of an NDI stream available on the local network (auto-detected);

• RTSP or VNC stream demonstration - the configured streams are displayed in the list.

To transmit RTSP or VNC streams, you must first add them to the address book as shown in the operator's guide. Then, create a device in the Presentation source section on the main screen.

To stream a PDF document, image, video file or HDMI content to the conference:

1. Choose Presentation source in the list above.

2. Specify the content source in the Presentation source list:

   • to select a file previously uploaded to the terminal, choose Downloaded Files from the list;

   • To upload a new file, click the Upload button;

   • To stream content from a source connected to the capture card, select one of the HDMI inputs.

   • To transmit an RTSP or VNC stream, select the appropriate option from the Presentation source dropdown list (it is generated from the list of allowed devices).

   • To stream an available NDI feed, select it from the list that will be automatically generated.

   • To display content from an additional camera, select it from the list.

If there are multiple connected cameras, you can specify which one should be used for sending video when configuring video capture devices. In this case any of the remaining cameras will be used for content sharing.

Now you can start sharing the selected content with your participants by clicking the Share button. If the call settings were configured to send the presentation upon connection of the source, the sharing will begin immediately after selecting the content.

To zoom in on the transmitted image or document and navigate through it, click the button in the preview window. In the control panel that opens, you can zoom and move the image using the respective buttons.

Switching Layouts

In the group conference mode, you can manage users' video layouts. To do it choose Conference layout or Main display in one of the feed displaying blocks in the drop-down list.

In the preview unit that appears, you will see a preview of the current video layout. To choose a new layout, click Change layout and choose one of the layouts in the list.

Mixing settings

You will see the following information about each video call participant:

• display name;

• Call direction (arrows are used to indicate incoming and outgoing calls)

• Address (may be SIP, H.323, RTSP, VNC, NDI)

• button to disconnect a participant from the conference.

• Icon if a participant is displayed in a spotlighted window
