Mike, re vdsl, 6 Mb pipes and headends

"Just having the pipe(a 6 Megabit pipe is not easy in itself) and is just one single part of broadcast quality TV."

An uncompressed HDTV signal is worth 1.5 Gb/s. Compressed? Somebody fill in the blank: _________M/bs. 170 to 270 sounds like a range that might fit in there. And lower, but the lower you go, the less "H" you have in HDTV.

"What about the hundreds of millions required to duplicate the cableco's headends? I don't know if it's just me, but there happens to be a few close by. And they are HUGE. I can hardly imagine what it costs to build and equip them. I wonder if there is going to have to be a significant shift in the entire broadcast TV model in order for the telecos to be able to afford to do TV. "

Those are analog entities you're referring to. Digital distribution nodes consisting of collapsed 10Gb/s switch arrays supporting central office host digital terminals will be far less expensive and require far less space and housekeeping, IMO. Of course, the delivery mechanism would be some form of FTTx.

Problem is, very few are even contemplating stepping up to the plate to put in a design which is digital through and through, as far as I know. With the exception, of course, of VDSL <even at full throttle 52 Mb/s>, which doesn't quite cut the mustard for up to three-program session delivery when one of them is HDTV.
