The Warp Expo West Live Video Feed


Saturday, September 18, 1999

Welcome to The Warp Expo West Live Video Feed,
courtesy of Demand Systems and Tim Katz.

The image you see will have a frames-per-second rate as high as your bandwidth and the overall system bandwidth will permit.

The video server is an Axis 2400 Video Server, supplied by Demand Systems. Engineering was done by Tim Katz of Demand Systems. The idea of having a live video feed at Warp Expo West was Tim's.

For the curious:

  • The Video Server captures the live video feeds from up to four different cameras and feeds the signals directly into the network. It has its own IP address and no intermediate computer or server is required.

  • The live video is supplied to HTML pages by a CGI request, and only requires a single IMG tag in the HTML code for Netscape or an OBJECT-/OBJECT pair of tags in the HTML code for Microsoft Internet Explorer (a small amount of JavaScript allows a single HTML page to work with either). Microsoft Internet Explorer requires the installation of a custom ActiveX control.

  • The images can be set to several different sizes and set at several different compression levels. Either a color or a black and white image may be selected, and the image may optionally have an overlay time stamp. The Video Server can also combine the four images into one tiled image, so all four images are seen simultaneously.

  • Full speed video at 30 frames per second is possible, although system bandwidth may restrict what an end user can actually receive.

  • The Video Server supports up to twenty simultaneous users, one or more of which may be relay points supplying many other users. If more than twenty users are connected to the camera, we don't know what happens.

  • At times one or more of the video feeds may be prerecorded.
