No Bert. The issue is that ~80% of U.S. homes are getting content from the the MVPD video network not via broadband networks today. We can quibble about the percentage given that many MVPD homes may be watching something via OTT streaming today, but the number of homes streaming versus those using dedicated video networks is relatively small. When the cable companies upgrade to switched packet networks to the home this issue will change, but it may take hearts. And with DBS it does not matter, as they cannot easily support millions of IP streams for VOD. > I wouldn't conclude that they're talking about IP delivery.

Whether they are using a proprietary streaming protocol or standard IP networks does not matter. The important detail is that they can deliver a sustained bit rate to every customer on a demand basis. They MAY be using a t and branch infrastructure where all of the live TV streams are sent to nodes closer to the neighborhood - this is what the cable guys are doing. But it is relatively easy to provision broadband to these neighborhood nodes as well as dedicated video streams.
