Re: How does DOCSIS 3.0 Fix this?
DOCSIS 3 would actually be a detriment to TV picture quality. DOCSIS 3 is for data usage, and its big feature is that it allows channels to be combined for internet access. So, use of DOCSIS 3 implies that more spectrum is going to be used. More spectrum allocated to internet = less spectrum remaining for TV.
DOCSIS 3 can, however, utilize the space above the current 900mhz range currently being used by the cable boxes. I beleive this is one of the reasons Time Warner is reaplacing our gear with 1ghz capable equipment in our area.
I also wouldn't rule out cable going with MPEG-4 for HD. They could just retask their old 641x DVRs for standard def customers. Its been several years since those boxes debuted, we're about due for a technology upgrade anyway. |

Valencia, CA | They need to use switched digital video to save up on capacity or go complete fiber (not likely to happen)

| I am actually curious about that idea. When ever techs came out to work on a problem, I would follow them around and talk with them. They said that fiber basically comes right up to the green box in our backyard and that coaxial cable just runs from that to our house. To me that looks like fiber is pretty darn close. |

Oh man but I thought the advertisements for comcast says the largest amd most advanced fiber network in the usa.
So does this mean they're lying? |
