What are Session Posters?

Session posters are placeholders that your users see in the content area when no content (livestream, video, conference, etc.) is being played at the current time. 

That is the case, when the session is not open yet or the session already passed.

Posters are often used to personally welcome participants in advance, to provide them with information about the session or to collect feedback afterwards.

Which posters are displayed when?

In STREAMBOXY there is the option to set an individual poster in three different statuses:

  • In the "scheduled" status, all users (speakers and attendees) will see the content you have posted. 
  • As soon as you open the room, your participants will see the content set for this status - speakers will see the session content (livestream, conference or content page) beforehand. This is the status "Open for speakers". 
  • A poster for the status "ended" is displayed equally to all users, but only if no recording is available.

What are the types of posters to define?

STREAMBOXY supports four types of posters.

Poster overview


By default, no specific session poster is defined. In this case the parent poster takes effect.

Individual: Website

Here you can integrate externally provided HTML pages and applications (if allowed by the owner) into STREAMBOXY as iframe.

In order to personalise the displayed content, STREAMBOXY allows the use of URL placeholders for the transfer of session title, user name, language, user identification etc. More information and help on this option can be found here.

Common use cases include embedded personal greetings, surveys, contact forms, etc.

Individual: Image

As an easier way to maintain session posters, you can export an image, for example from PowerPoint or Photoshop, and upload it to the Content Manager.

You can crop and adjust the posters to a 16:9 format during the upload. After uploading, the image is compressed for faster delivery and automatically adapts to different screen sizes.

Further information on the image editor can be found here.

Then click on the folder icon to select the appropriate item from all the content already contained in the Content Manager.

choose an Asset

Once you have selected a poster, you can click on the title of the asset next to the URL to edit it again and to see a preview of the poster.

When you select "Template", you can choose the type of template in a dropdown. STREAMBOXY offers you a poster with countdown or a session planner.

Poster with countdown

If you select "Poster with countdown", a countdown to the start time of your event will be generated automatically. The background can be adapted independently. Each participant is personally welcomed ("Welcome "Name of participant") and the title of the event is mentioned ("at "Name of event").

Example poster with countdown (the name of the participant here is "Admin"; the title of the event is "Test"). The event will start at this time in 15 hours, 18 minutes and 33 seconds.

Session Planner

Select "Session Planner" in the dropdown under "Template", then a Session Planner appears in the corresponding status on the screen interface. A Session Planner lets you add the corresponding agenda item as an entry in your calendar. 

For a Session Planner, you first need a STREAMBOXY event with various subsessions. These are displayed in the custom agenda. It is important that the visibility in the portal settings of each subsession is configured for "logged in users" or "anonymous users". Visibility must also be configured for "logged in users" or "anonymous users" in the portal settings of the event. 

If you enter the correct URL on the content page, the subsession will be displayed in your custom agenda. 

To include the custom agenda in STREAMBOXY, you must include the STREAMBOXY URL placeholders as query parameters in the custom agenda URL. 

You need the following URL parameters: 

  • userToken
  • tenantId
  • eventId

An example can be found here: https://samples.streamboxy.com/custom-agenda?token={{userToken}}&tenantId={tenantId}}&eventId={eventId}} 

This example URL could be inserted into a URL input field of a content page in STREAMBOXY.

Example Stage with Session Planner from the participant's point of view: 

Participants can now use the Session Planner to save the various subsessions as an entry in their personal calendar and/or add the corresponding subsession to their personal (customizable) agenda. In this way, participants can put together their own individual agenda.

Where are posters defined?

Poster Hierarchy

The posters are arranged in a hierarchy and inherit the settings to the respective subordinate position.

The more specific setting always overwrites the parent setting.

If no setting is defined, STREAMBOXY shows the logo you set with a short info text.



Tenant or client-wide setting

The configuration of the tenant posters can be found as menu item Posters in the Settings menu. 

These posters are valid for all events of the tenant or client, as long as no own definition has been created in individual events.

Poster overview

Event setting

The configuration of the event posters can be found in the settings of the event under Posters. 

These posters are valid for all sessions of the event, as long as no own definition has been created in individual sessions.

Session setting

The configuration of the session posters can be found in the session settings under Agenda and Sessions.

These posters only apply to the individual session.

Edit agenda items or sessions

Edit Session

How long does it take for my change to be visible?

Changes to posters are updated immediately for all events, sessions and attendees. 

Posters update for the attendee without the attendee having to reload the page to do so. 

This allows for last minute adjustments or during ongoing events.
