CenturyLink is our local Teleco. They are pitching Prism. All these schemes like U-Verse, FiOS and Prism appear to have the same problem, significant limitations as to the number of simultaneous channels that can be viewed. Prism offers two HD Streams and two SD streams. That sucks if you want to have seven televisions in your home accessing different channels.
I understand that U-Verse and FiOS have similar restrictions as to the number channels that the subscriber can view through one drop at one time. The teleco's attitude seems to be that we are not Burger King so have it our way or blow it out your ass.
The teleco's should have beat CATV at there own game and used RF over Fiber like the cable companies do. A 1GHz system would have given teleco., the ability to carry a bazillion channels plus voice and data. Tell teleco not forget to reserve 1Mhz to 114Mhz for upstream channels over their cable system.
