All things related to multicast

[Alan Buxey <>]

hi,

yes, think multicast is technical and complicated - you havent seen broadcast
rights and legal ownership statements! ;-)   the broadcasters often have the 
right
to show a production within a territory via a technology... they dont own the
rights to show it anywhere else or via some other means.  the production 
itself is
protected and ownership of that can be multi-depth.   a few stations would
love to spray their stuff all over the place - as you say, Ad revenues could 
be huge!
(though how do you prove that someone was watching with standard multicast - 
thats
one of many issues).

as for worrying that someone from outside the geographical region could watch 
services..
i know of countless territory VPN services that exist (at very cheap monthly 
service rates)
solely to enable people from other territories to watch geographically locked 
content -
eg BBC iPlayer is viewed by people all over the world via VPN links back to 
UK.... and
you can do the same with multicast too.  the trouble with tech is it causes 
the people
who crawled through the industrial revolution and the 20th century 
developments to have
knee jerk reactions rather than embracing the zeitgeist
