1 edit | Re: Rural General Suckitude said by jmn1207  :said by SilverSurfer :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. 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.

2 edits | Re: Rural General Suckitude 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. | |

And I wouldn't be surprised if the FCC also allowed adjustments in transmitted power so that the digital stations get a further reach(similar to the analog coverage) in order to cover areas like those on the map in orange.

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.

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

That's actually worse since WPVI-DT doesn't come in very well currently. I shudder to think of what it will be like after the switchover. | |

Norwich, NY | 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. | |

| that would help increase bandwidth efficiency so you could get a better picture or sound, but not raw signal strength.
cell phones work because there are towers all over the place. If you paid $50/mo for tv service you could have similar land based radio coverage. | |

| said by jay_rm :In the little testing I've done, the analog quality would have extra-high suckage. I've seen perfect DTV picture quality with no drop-outs when the equivalent analog channel was so snowy it was no more then a ghosted black & white eye-hurting remnant of itself. Looks to me that the DTV signals need very low S/N to work just great. This could very well be caused by different Multi-Paths between the different frequencies the analog and digital are transmitting on.

|  It's not even just as simple as you either get it or you don't, all of the tv channels I get that are digital are choppy if I don't have the antenna adjusted just right for each channel I watch I have to constantly adjust my rabbit ears or the digital channels break up into little squares and then the screen freezes for minutes at a time, then picks up the signal again for a minute or two then cuts back out. atleast with analog you could still watch the show with out interuptions even though the picture might be a little fuzzy. | |
