kudos:12 | Bandwidth Crunch is Real? I'm starting to believe that cable may be in a worse situation without DOCSIS 3.0 than I thought. Time Warner is having all kinds of SDV bandwidth issues in my area as they try to squeeze more HD channels in. I frequently change from a channel, change back only to have it tell me that channel is unavailable. 3 tech vists, 2 supervisor calls and I've been told they are simply out of bandwidth and are aware of the issue. I've also noticed my picture quality going downhill. TW has never had issues in this area and it's not especially densely populated.
I did find it comical when the tier-1 rep tried to blame it on the DTV delay however. |

kudos:12 | said by fifty nine:They'd better hurry up and switch to MPEG4. Does cable have plans to do that? I haven't heard anything along those lines, but I agree. That would what, drop their video bandwidth consumption to 25% of what it currently is? |

Programming providers are also doing lots of MPEG4 upgrades as well. |

kudos:12 | Well, okay. I know they have been talking about it (one of your links is 10 years old) but I meant do they have any firm plans? Time Warner doesn't even have hybrid boxes (much less full-blown MPEG4) available.
Can they get away with using a dongle like DTV does for some of their boxes? |

| There are MPEG4 STBs, some have been showcased at CES.
Customer owned devices like TiVo are already MPEG4 capable. |

Hanover, PA | x264 is an open source encoder.
MPEG4 Part 10 aka H.264 or AVC is the name of the codec. |

Yes it's real. It's mainly the fault of the suits, who raked in the cash for many years, but never thought people would literally use the internet. Verizon's analysts, for-seen the big internet boom, and people using their internet connections more and more.
Cable's biggest problem to date, is their last mile runs. They refuse, to upgrade their outdated, coax hybrid plants. They'd rather squeeze out as much as they can, because in their eyes. What really is the point of spending all this capital, when only 1% uses it! (remember 1% are the evil bandwidth hogs, claimed by many different ISPs)
TimeWarner Cable here in NYC - has the HD problem, they've squeezed so many channels in, but its too flaky. Channels say unavailable, channel changing is fun too, because sometimes you get 'stuck' in a very wonderful loop.
Docsis 3.0 means nothing, if they dont upgrade their plants. TimeWarner Cable is still on Docsis 1.1 - From reading various sites, and from the own horses mouth, they have no plan or intention to upgrade to 3.0 anytime soon.
this should be good times, good times.

Jewett City, CT | HFC isn't outdated. It's just a medium that isn't being used all that efficiently right now primarily due to analog channels.
Drop 30 analogs = 1Gbit/sec+ of DOCSIS data
Drop 30 analogs = At least 60 HDs. More with SDV & MPEG4
The lower end cable systems are typically, at least, 550MHZ of bandwidth. That's more than enough if you manage it correctly but it's going to require the death of analog cable, cheaper downstream prices for DOCSIS, and more interoperability between EDGE QAMs so a particular node group can utilize this massive amount of bandwidth for the specific services/channels they are demanding. |
