Of course, this below is for inter-domain. There is no shortage of multicast walled garden deployments. Regards Marshall On Jan 12, 2007, at 7:44 PM, Marshall Eubanks wrote:

Not to end users.
I think multicast is used a fair amount for precaching; presumably that would increase in this scenario.

P.S. Of course, I do not agree we are moving to a pure VOD world. I agree with Michal Krsek in this regard.

Hi Marshall,
- the largest channel has 1.8% of the audience - 50% of the audience is in the largest 2700 channels - the least watched channel has ~ 10 simultaneous viewers - the multicast bandwidth usage would be 3% of the unicast.
I'm a bit skeptic for future of channels. For making money from the long tail, you have to have to adapt your distribution to user's needs. It is not
only format, codec ... but also time frame. You can organise your programs in channels, but they will not run simultaneously for all the users. I want to control my TV, I don't want to my TV jockey my life.
For the distribution, you as content owner have to help the ISP find the right way to distribute your content. In example: having distribution center
in Tier1 ISP network will make money from Tier2 ISP connected directly to Tier1. Probably, having CDN (your own or pay for service) will be the only one way for large scale non synchronous programing.
