Over twisted pair copper? Current speeds in Gainesville are between 4 and 12
Mbps, but most get only 4-6 Mbps. The only way I can see DSL reaching 1 Gbps
would be fiber to the neighborhood with very short runs over copper.
I think that the Telco's are going to move to wireless from fiber risers in
neighborhood.
It is the MVPDs who are going to get out of that one-way broadcast, and use
IP efficiently. This is to make better use of their deployed infrastructure.
Agree that they are moving to an all IP infrastructure. But they will continue
to deliver linear streaming channels for many years to come.
I doubt they would offer hundreds of streams, but something in
the range of "17" is quite possible.
Once again, Craig, "live" does **not** automatically require "broadcast."
"Live" is best multicast, if it has to go "live" to masses of people.
Otherwise, unicast live content. Explain in detail why you continue to think
that broadcast is needed. And before doing that, define broadcast and how
it's different from multicast.
Semantics. We are moving from channels that deliver bits via MPEG-TS to IP
multicasts and unicasts. The big change is that with IP multicast the operator
knows who is tuning into the multicasts, not just the unicasts.
Again, that number "17" most likely means that people want "17" sources of
content. Only these people, and the guy taking the poll, were probably using
archaic terminology to describe what they really meant. No reason to latch on
religiously to something so imprecise.
They were talking specifically about core channels and all carte add-ons. I
have no problems with calling them sources, as each source will likely offer
both a streaming channel and access to their program library. It appears that
the trend is moving toward smaller core bundles like Sling, with much more
flexibility in the choice of add on "sources."
DNA evolves Bert.
Evolution does not mean going backwards to the stone age, Craig.
The Stone Age would be families sitting down on Tuesday night to watch Happy
Days and the rest of the shows that followed. Getting people to sit down for
appointment TV is challenging, but not dead. Anywhere, anytime TV is now a
reality, but sometimes that reality will be tuning into a linear streaming
program. There is no reason that linear streams and VOD cannot co-exist.

Craig
