Ragnor:raytaylor: sorry i should clarify what i ment
tv via fibreoptic cable, or cable. Telstra's network is HFC which is a blend of the two - hybrid fibreoptic coaxial
but a company could create an all-fibre cable tv network in NZ using the UFB and deliver tv services using radio over fibre transmission and renting dark fibre, or if they rented layer 2 fibre, they could use multicast tcp/ip
The question is why.
I think broadcast TV where you have a large number of people watching the same show at the same time is in slow decline. Live sport and maybe news are two exceptions, everything else is better on demand (see the popularity of tv episode and movie downloads/torrents).
Sky already has their satellite infrastructure, freeview has satellite and uhf, Telstraclear cable - it would only make sense to move to UFB for Telstraclear out of those three in the medium term. There's no really space for another broadcast network, what content would they possibly be able to run?
Personally I think the future in on demand for everything over the internet.
Exactly. A large ISP / Content provider can have large web caches and tv programming caches at each major exchange
Sky will want to be on board for any ufb tv system that could be created, as they are with telstra clear otherwise they may loose out on subscribers to another international company that decides they want a cheap way to expand into NZ.
