We support progressive media streaming. You can embed it into your site using hyperlinks.
We don't have a dedicated streaming server, nor do we offer other forms of live streaming. Progressive media streaming means the file would stream while the page is loading rather than wait to play after it has been fully loaded. We offer both progressive streaming and a full download prior to playing based on the code you use on your pages. We do not, however, offer a server just for streaming media.
