If you guys can't see the prospects of this technology you've got rocks in your head. Everyone gets their own TV station. Unlimited discretionary broadcast of any content you wish. Now that's something.

Hello Roger, I am in agreement with much of your posts in the recent days ... > your assumption about how radio on the net works is also incorrect, > because each user is initiating a non-simultaneous transmission of > the same content, just to them. The key in this is "from where"? Are the users pulling streams all the way from the origin servers? I'll address this more below ... > Even in circumstances where sharing bandwidth is possible in > principle, you need multicast to make this happen. I won't repeat > my previous email here. Working in research in this industry I have to say that I am not a fan of multicast for the majority of applications. I believe that hierarchical caching is a better solution. And hierarchical caching of multimedia content will be a better solution, IMHO, than other technologies. > Multicast and MOD are different. MOD is the view of what the user > is doing. Multicast refers to how the network and different servers > handle this user request. Agreed. And as you stated before, with out caching there is no pause, rewind, or bandwidth benefit. Multicast in general offers streams to everyone at the same time. I can't start a stream 10 minutes after you without missing the first 10 minutes, or creating additional bandwidth demands. > The key point here is that bandwidth demands are exploding (around > 300% a year), and operators will be using every technology they > can to expand the effective bandwidth, and that includes > using efficient compression algorithms, even once multi-cast > technologies are in place. And I would argue that if you look at some of the recent annoucements (by companies like U.S. West) they are starting to invest in hierarchical caching technologies. These caching technologies will start to cache content at the CO levels and even in the home (to allow replaying content without leaving the house!) > No industry has ever seen this kind of > sustained growth in demand and performance, and managing it is not > a small undertaking. I agree completely! Scott C. Lemon
