I guess to put it more succinctly, I would not expect a new VOD source to 
require more network bandwidth? VOD is by its nature a one-to-one proposition. 
A subscriber is unlikely to be watching more simultaneous VOD streams, just 
because a new VOD option is added.

I would expect more VOD to involve more server capacity. Not sure what you mean 
by "The video asset it trucked from the VOD farm (where the assets are stored) 
to the pumps sites, ..." Are these "pumps sites" edge storage?

For a service like this hypothetical Netflix-to-in-home-TWC-STB, I would expect 
it would be entirely VOD regardless. The Netflix scheme doesn't include live 
streams, right? So they wouldn't be using the "live video" bandwidth, aka 
MPEG-2 TS broadcast streams, *unless* TWC only offers VOD by means of in-home 
PVRs. I doubt they do that.

So, whatever bandwidth TWC uses for their own existing VOD service is the same 
bandwidth a Netflix VOD service would use. I assume that even the legacy TWC 
VOD service is provided by servers at the edges of their walled garden network 
(don't know if it uses IP or other).

My colleague at work had Verizon FiOS installed some time ago. They have been 
using IP (unicast, obviously) for all of their VOD, from the start. It makes 
sense. Why reinvent the wheel?

Anyway, if TWC already uses IP for their VOD, as Verizon FiOS does, then it 
seems to me that the protocol and the "bandwidth" problems are already solved. 
VOD can't use MPEG-2 TS broadcast bandwidth unless the VOD is provided only by 
in-home PVRs.
