IP Multicast as a solution to video distribution is a non-starter. IP
Multicast for the wide area is a failure. It assumes large numbers of
people will watch the same content at the same time. The usage model
that could work for it most mimics the broadcast environment before
cable TV, when there were anywhere from three to ten channels to
choose from, and everyone watched one of those. That model has not
made sense in a long time. The proponents of IP Multicast seem to
have failed to notice this.

Because people want to watch what THEY want, when THEY want. Even if
you consider the possibility of live content, you should indeed look
at radio. You can listen to a live stream of huge numbers of radio
stations from around the world. If I want to listen to WBCR-LP (a low
power community station in Gt. Barrington, Massachusetts) I can tune
in easily. It makes no sense to feed it over multicast, as it's
doubtful there's more than a handful of others anywhere
topographically (network-wise) near me to make it make sense to have
routers handling multicast for this stream. The point is the more
possible live content there is, the less multicast makes sense.
Compounding this, fewer people care to watch live content, preferring
instead to record and watch later on their own schedule, or be served
on-demand. In this usage model, multicast is not helpful either.

There may be a dark horse, but I doubt it'll be IDMR. A more likely
one, IMO, is cache stuffing by statistical approximation... what I
mean by this is best explained by example... the satellite providers
could add broadband connectivity to their boxes (the Dish receiver we
have does indeed have an Ethernet port, so this isn't difficult to
imagine). Where the boxes could use the broadband connection to pull
demand content, the higher bandwidth of the satellite link could be
used to push the most likely requested content to the hard drives of
receivers. Hybrid demand and prediction is just a guess of where
we're headed, of course.

Dish has a button that advances 30 seconds per click. Only way to
watch anything these days is to have control to fast forward. Better
yet, just shoot your TV and read a book. The entertainment value is
greater, and it's a lot more energy efficient.
