Overview

As part of Division of IT 's continuing commitment to serve the campus and its academic endeavors, we provide the capability to stream live events or lectures. Streaming media makes content easily accessible to several locations at once.

Streaming technology works by allowing viewers to watch video while it is still loading on the backend. The servers providing live streaming at Division of IT are Helix streaming server and Darwin streaming server. Users can broadcast live lecture or event using either method. Below are the highlighted differences between using the two options.
