Since I have that analog cable there is one key feature that I like. It just works. On every TV, every VCR, and my media center computers. Plus it does that in every room.
The moment they go to digital I lose all that convenience because cable companies (and others) insist on mucking up the signal so that I need a set top box. Now I'm tied to the set top box. One room per box, my media center quits working, my VCR can't record the occasional show, and so on.
They could fix that, but based on past experience. They won't.
This story must have came from sources that never consulted anyone that knows cable TV systems.
No need to buy any Cisco IPTV gear - yet. Just kill off those analog channels that have been taking up space. Let me explain:
If a cable system is last year's state of the art it could have that mentioned bandwidth - 750 MHz.
Same cable system has sayyyyy, 80 basic channels all sent in analog to keep the 1957 era Philco TV usable. At 6 mhz per channel they take up 480 MHz of the available bandwidth, leaving 270 MHz for all those digital channels, premium channels, their own VOIP service, HD channels, internet service, pay per view etc, etc.
Digitizing those 80 channels at 6 to 1 compression would fit them in the space of less than 14 analog channels.
So, we have 84 mhz for the now digitized analogs, 270 for all the rest of the present stuff, thats 354 mhz. Same content using half the capacity.
IPTV? Cable has been doing that for a while - Video On Demand is the same as IPTV, content stored on a server, requested by a customer and streamed in yet more open space.
Coax may not be as sexy as fiber to the curb, but it can do everything fiber can do. Without a big capital cost and without petering out when you live a few feet too far from a Ewe-Verse firebox.
Been listening to the podcast ever since seeing it at CES this year. I stopped for the free seats and kept coming back for the show . .
