Why would the PON need to be restructured? DOCSIS 3.0 downstream is MPEG-2 TS.

You can't fool mother nature, Craig. The amount of spectrum dedicated to
one-way broadcast MPEG-2 TS, in a cable system, can instead be used for 2-way
IP broadband, every bit as much as this applies to OTA spectrum.

That's why the cable companies themselves have an incentive to change the way
they do business, and to retire the broadcast streams. Yes, they have this huge
installed base of obsolete STBs which depend on MPEG-2 TS broadcast streams,
but they also have cable and fiber installed in all these neighborhoods. The
more they retain the old broadcast MPEG-2 TS, the more PON physical
restructuring work they have to do, to offer increasing bit rates to their
customers.
