Webinar Technical Requirements

We’re often asked what the specific requirements are for a company or individual to attend a WorkCast Auditorium and view a live video stream. Here’s the low-down on all things technical.

What are the browser requirements?

The first point to note and one of the main features that put WorkCast ahead of our competitors is that there are NO WorkCast downloads or plugins. Our Auditoriums work across all major platforms, in all major browsers, using standard web-based technologies. The experience will be tailored based on the viewer's platform and features available within the viewer's browser including HTML5, flash, and numerous other attributes.

The WorkCast Platform can be configured to deliver content using secure (HTTPS) communication protocols. HTTPS requires TCP port 443 to be opened through your firewall for both inbound and outbound traffic.

As with most websites, there are certain browser options that must be enabled to allow full functionality and we’re no exception. In order to enable our full feature-rich viewing and interactive experience, javascript must be enabled.

Cookie support is an added bonus to help enrich the experience but is not essential.

Presenter Studio View - Requirement Summary:
