What is a Webinar?

A webinar is a presentation, lecture, workshop or seminar that allows you to view the presentation, chat and speak in real-time over the internet. The online conferencing system, Blackboard Ultra, used for the Webinar Series provides the most accessible conferencing and collaboration experience possible. Individuals can participate in a fully-accessible, online conference from anywhere that they can access the internet.

Blackboard Ultra is a simple, convenient, and reliable web conferencing solution built for training. Engage with the material and your instructor. Thanks to robust collaboration and conference tools, everyone feels like they're in the same room together, regardless of their location or device. If you plan to log into the on-line webinar system to view the presentation, listen to audio, chat, access captioning and Video Sign Language Interpreter (if provided) and/or submit questions it is important that you use a hard-wired (Ethernet) connection, if available. If not available, use a Wi-Fi connection. To learn more about Blackboard Ultra experience visit https://help.blackboard.com/Collaborate/Ultra/Participant/Get_Started

Ultra Network Requirements

IT administrators may have limited how devices on their networks can make connections and detailed information is available for Ultra networking for IT Administrators.

UDP networking

Ultra works best when allowed UDP traffic on ports 49152 through 65535 for the domains: *.bbcollab.com, *.bbcollabcloud.com, *.bbcollab.cloud. If that is not available UDP traffic on port 50000 will also work.

Web Sockets

Whitelisted *.bbcollab.com, *.bbcollabcloud.com, and *.bbcollab.cloud domain to allow HTML5 Web Socket traffic to connect to session servers.

Error Messages

The J10 and J11 error messages indicates your system is blocking the special HTML 5 web socket connections that Blackboard Ultra uses. This type of error messages is usually the direct result of a network firewall configuration by your workplace IT and that means that the only solution is to have your IT operations make modifications to allow your device to join the session. To participate in our webinar using the Blackboard Ultra service your device needs permission for WebRTC over the User Datagram Protocol (UDP) and HTML5 Web Socket traffic to properly connect to the session servers.

What is Closed Captioning?
