Stormy Waters: Multi-Cast Glasgow
The Internet Connection

During Stormy Waters, Internet transmissions from artists around the world travelled by various diverse links to converge on SuperJANET, the UK Research Network. The digital signals travelled up the spine of Britain on fibre optic to reach the at the University of Glasgow. There the data was queued and organised on multimedia workstations. InterLynx Ltd had the responsibililty for world-wide liaison with the digital artists, orchestrating the multiple live Internet connections, and final delivery of the multimedia imagery. InterLynx's roles ranged from developing the artists' world wide web site, to coordinating the contributions of local companies like Sun Microsystems, Scottish Telecom and Datarange, all of whom pitched in with substantial equipment and manpower aid to enable worldwide communications.

The digitised pictures were transferred to a vantage point high up on a tower of the University of Glasgow , where the signals were routed onto a radio transmitter dish and beamed at 8Mb/s over the city of Glasgow to the event site 2km distant on the River Clyde. At the event site this data was channeled to an ethernet linking the on-site workstations wherein the digitised art was transduced to video feeds for display.


On The Mbone

The Clyde not only received incoming digital art, it also broadcast the whole Stormy Waters performance live around the world on the Internet Multicast Backbone (mbone). The mbone is a means for efficient transmission of video and audio data across the global Internet. Audio and video of the Stormy Waters event was digitised on-site and beamed back to the University tower. From there it was multicast on the global mbone and audiences around the world were able to witness Stormy Waters live on their own computer screens.

The Stormy Waters live broadcast was advertised in the LBL Session Directory and was broadcast on a Multicast Address, with the tools VIC, VAT and WB. For CU-SeeMe, there was a reflector on-site.
