On the Space Architecture Bibliography page, the Video buttons link to video streams of conference presentations. To view these video streams, you’ll need a browser that supports the RTSP protocol.
Older browsers that don’t recognize the RTSP protocol may not parse the “rtsp://...” URL correctly. They may try to interpret “rtsp:” as a server name or part of a document name. If your browser reports that a URL with “.../rtsp://...” was not found, or that it “is unable to locate the server rtsp:”, or that “rtsp is not a registered protocol”, then you’ll need to try a different browser. Note that “rtsp” is the “scheme” part of the URL and designates the protocol, not the server name or relative path name.
