All things related to multicast

["Michael Luby" <>]

Yes, we at Digital Fountain have a product that provides VOD using multicast (although it is not "cycling through", it is always creating unique encoding material about each section, but it is based on ideas that are related to the pyramid scheme).   See http://www.digitalfountain.com/products/streamingFountain.htm for details on this specific product (and http://www.digitalfountain.com/products/index.htm for the full family of products, all of which can deliver using multicast transport).  And yes, I believe that Greg is at least sometimes sourcing streaming VOD content using multicast using our Streaming box.

Dear Zhu;

   We have continual broadcasting of audio and video multicasts on the
Internet. Is that what you mean by
periodic ? Or do you mean a cyclic multicast of a loop to emulate video
on demand ? Digital Fountain has such a product, and Greg Shepard was
running a test of it from Oregon. I am not sure if it is up, but I am
sure he can tell you about it.

Test your network for multicast :

Our streams :
Audio - On-the-I.com
MPEG-4 video  - www.multicasttech.com/otv

Greg is cc'ed above.
