That's how all the set-top-boxes in the hotels are "imaged". The data
image of the box rotates on a "channel". When the box is rebooted is
scoops up the image from the DVB stream to reappear with glittery new

As for "IPTV",  to me the term means the SD and HD broadcast TV
channels delivered in a DVB stream. The streams are sourced from the
sky, and Internet2. Multicast (the piping of these streams to the
class "D" IPv4 address range) is a request and routing protocol that
distributes a requested TV service (2-24 Mbps) in the most efficient
way across networks of any size.

Now, IPTV means anything from watching video on the internet to
YouTube playing on your TV. It's term used very awkwardly these days.

I reckon a national multicast network will spur some new uses, other
than delivery of live TV. As Stil says, live video from anywhere to
everywhere is valuable content for much smaller audiences. Especially
in a cyclone.
