ftth, Current encoding standards have 'VHS' quality with MPEG1 which is roughly 1.2mb. The 'DVD' quality level is usually delivered at MPEG2 at various speeds, but testing I have seen shows good signal quality at about 5.4mb. The reason may of us use ip multicast is to get these streams to an audience without forcing the server or the backbone to deliver them hundreds of times. They must be using their 'meta' process to further compress the signal, but in a revolutionary way if it works as advertised. Please note I have no knowledge of their process. One flaw in the ointment - many backbone providers including UUNet and Sprint already support IP Multicast. John
