Are you saying that, when the NBN is being used as a broadcast network
by a multicast TV source, NBN Co will have to switch the signal to
each subscriber and block it to those that don't subscribe? That is
certainly not how the HFC network works. It would explain why you
believe that "cable" TV over the NBN will not require a set top box.
_Every_ network requires a circuit from the source to each desired
destination. I suppose that a ring topology might be regarded as a
"single circuit" but that is not the network model being implemented
by NBN Co.
On the contrary. There is a circuit from the transmitter to my TV
aerial and a circuit to every other aerial in range. If you happen to
be confined to a Faraday cage there will be no circuit and you will
not receive FTA TV.
Re: NBN continues to impress
*I* didn't say anything. That is from the Encyclopedia Brittania. If you
still don't know the difference between point-to-point and broadcast
networks, I suggest you Google for yourself at this point.
FM radio is "broadcast". Walkie Talkie's are "point-to-point".
Normal TV is "broadcast". Fibre is "point-to-point".
One, single circuit for every user. Unlike point-to-point media like fibre.
