I don't know which is worse in rural areas...the fact that the phone lines are and have always been for shit, or, the fact that you can't even use good ol' rabbit ears to pick up any TV signals anymore. |

Why can't you use rabbit ears? I can pick up digital stations using a wire coat hanger with no degradation in quality. It's digital, so you either get it or you don't. It's not like the analog signals that would vary in quality depending on the strength. Rabbit ears will work just fine. |

It's not like the analog signals that would vary in quality depending on the strength. Rabbit ears will work just fine. The issue is that the digital signal has a sharp cutoff where you either get the signal or not. The analog signal would degrade over distance but still provide a viewable channel, even if the quality sucked.
This map of the coverage in the Wilmington test shows how the analog transmission had a farther reach. The digital coverage was helped by overlapping digital signals from nearby affiliate stations on the same network. But the area in orange basically lost all NBC coverage in the switch.

And here I thought the FCC had conducted tests to ensure that the coverage would not be diminished when the switch to digital was made.
I wonder how this will impact satellite TV and local channel distribution. In areas where local networks were not included with DirectTV or Dish, you had to live outside the range of the local analog signal's reach to be eligible to get generic network broadcasts piped to your satellite receiver. I suppose the distance requirements will have to be adjusted accordingly. |

Hopefully there won't be any situations that might cause one signal to bleed over the top of another. If that is even possible with this type of signal. I know with my radio stations I can make a mix of Mexican Radio meets Contemporary Jazz. This occurs late in the evening and I call this music style, Contexican Jazzio. |

If I recall correctly, many stations whose frequency lies within the VHF range will actually be broadcasting with less power to prevent interference with FM stations. Plus they don't pass through physical objects (walls for example) as well as UHF frequencies.
Many of those stations are currently broadcasting in the UHF frequency range, but will switch to VHF after Feb 17, 2009.
For example Philadelphia's KWY-DT (CBS) is currently broadcasting on a UHF frequency (don't have it in front of me at the moment), but will switch to channel 3 after the switchover. That means people who can receive the channel now, might not be able to get it after the transition.

That's the same percentage of people who (supposedly) still have dialup, but no one caters to that class.
Why should this be any different just because it's TV? |

The last I read for this area the FCC had cut the allowable transmit power to prevent interference to stations in the Midwest.
Creating the problem of no receivable stations even with a large fringe antenna. |

Well, we could at least get a crummy, snowy reception of Jeopardy if Uncle Bill, with a metal plate in his head, sat on the love seat near the window. It was something, just like dial up. Better than nothing at all, perhaps, or maybe losing TV is the best thing that will ever happen. With no TV, one might expect to see increasing levels of reading comprehension in those areas. |

After looking at that thread I came across this link that will allow anyone to stay on top of the OTA digital plans and follow thru.
»www.rabbitears.info/dtr.php
And if you do a zip code search and keep the mileage option to 40, you should be able to see what is/will be available digitally on 2/17/2009 in your area.
»www.rabbitears.info/search.php
I have tested for my area and can get all the stations listed with rabbit ears and a converter box up to about 35 miles away.
Here is an example of what is available when using search and listing tools:

said by Oleg :everyone has digital cable or satellite anyway. As jmn1207 posted about 12% of us rely on over the air transmission.
Conversion to DTV is actually increasing number of people using over the air antennas. OTA typically has better picture quality then Cable or sat because it is not recompressed to reduce bandwidth usage. In addition in these poor economic times I'd be willing to bet some folk are going back to OTA to save money.

Actually, in Philly, it's WPVI-DT (the ABC station) that's moving their digital signal back to VHF-Lo, not KYW-DT. |

CBS isn't compressing and has only 1 digital channel to use their bandwidth.
But ABC cut up its bandwidth to squeeze in more sub channels.

What I meant was programs broadcast over the air are often recompressed by Cable and Sat providers to squeeze more channels into their channel capacity reducing quality compared to what one gets with OTA.

8.6mbps MPEG-2? Yuck!
Problem is, cable or sat is going to use WPVI's 8.6mbps ABC broadcast as their source. So no matter where you go, it's going to, at best, be that same 8.6mbps crappy quality, perhaps with even more artifacts introduced if it's transcoded to MPEG-4 or pushed through a cable company compressor to guarantee WPVI doesn't change their mind and up the data rate. It's unlikely that TV providers are going to go through the trouble to get their encoding equipment installed at a point prior to being compressed for OTA transmission.
You have, however, perfectly illustrated why I cringe when people say OTA is superior because it's "uncompressed". As you've shown it may be compressed quite severely! Many cable systems just remux the same quality data onto a QAM stream.
