Most cable companies don't give that kind of bandwidth to their customers (coughCoxcough, coughComcastcough, COUGHcharterCOUGH, coughAdelphiacough) and nor do DSL give as much either |

| My D-VHS D-Theater unit runs at up to 28Mb to deliver 1080i. Even crap DVD is 6-10Mb. And by the time telcos actually get off their ass and deploy even decent 1.5Mb service, HD will be old news in favor of something else.

Why would a Cable Co. Need to deliver HDTV over DOCSIS? They just do it in a 256 QAM carrier.

I said a few weeks ago that they would have to resort to sending video feed in mpeg-4 compression. zzt zzt divx is taking over. If they were able to get it down to where it was less then 5mbps they could fit it over existing cable (OOL for example) or adsl (verizon 7.1mbps for example) which could be feasible. now if only I could flick a switch turning that bandwidth normally for television signals into bandwidth my w4r3z downloadz0rz |

That bandwidth will be clogged with dozens of not 100's of regular HDTV feeds by 2006 if the FCC has their way and if I'm not mistaken HD feeds take about the same bandwidth as 6 regular NTSC feeds so no matter what happens, bandwidth will be a premium both for HSI streaming services as well as their regular DCATV/HDCATV services.

It's not as simple as that. You can have 2 HD and a SD or two in a 256QAM with Rate Shaping. If you look at 1 analog channel that takes up 6Mhz of spectrum and you replace it with 2 High Def's and 1 Standard Def in a 6Mhz wide QAM. your getting 3 channels for the price of 1. I fail to see your logic.
A 8VSB over the Air carrier has a HD and a SD |

All the FCC is requiring is that OTA stations (CBS, ABC, FOX, NBC, WB, UPN etc.) must broadcast HDTV. Cable companies will still be able to send analog signals over cable and the same goes for satellite. The only reason the FCC is making broadcast stations switch is that they want the spectrum that they are currently using.

| The FCC is only requiring that stations broadcast in digital. Not High Definition. There are several stations in the Chicagoland viewing area that broadcast nothing but standard material over the digital stations. Fox has the "enhanced definition", and one station that has 6 sub channels all with different programs going on (they must be loving it). |
