Silverlight is a 'plug-in' for delivering media and rich interactive applications for the Web. It's a way to ensure that video will play in your Browser
It is freely available for all major browsers including Mozilla Firefox, Apple's Safari and Windows Internet Explorer running on a Mac or Windows.
Microsoft's new ‘Edge’ browser (included in the recent Windows 10 update) does not support the Microsoft Silverlight plug-in and support for Silverlight has also been removed from Google Chrome. However, we have also used MPEG-DASH streaming support to make sure your experience in these browsers is not impacted.
